- Understanding Statins, Cholesterol and Heart Disease
According to the NHS Choices website, “statins are a group of medicines that can help lower the level of LDL (low-density lipoprotein) cholesterol in the blood. “ It goes on to explain that LDL cholesterol is often referred to as “bad cholesterol” and that statins reduce the production of it inside the liver. Explanations such as this, however, can give rise to confusion. There is no such thing as ‘good’ or ‘bad’ cholesterol. There is only one type of cholesterol, made up of 27 carbon atoms, 45 hydrogen atoms and an oxygen-hydrogen pair. You can search as hard as you like but you will never find any other type of cholesterol! Good vs. Bad Cholesterol Confusion Cholesterol consists of three parts. Two of the three cannot be dissolved in water. This means cholesterol is incapable of dissolving in blood. In order to get to the cells where it is needed, it has to be transported throughout the bloodstream. This is where lipoproteins come in. Lipoproteins are vehicles that transport cholesterol around the blood. Lipoproteins are a combination of various fats (lipo) and protein. Unlike cholesterol, of which there is only one type, there are different types of lipoprotein. Lipoproteins are classified according to their density. Two of the most important, in terms of cardiovascular disease, are high-density lipoproteins (HDLs) and low-density lipoproteins (LDLs). Lipoproteins are the taxis that carry cholesterol around our bodies. HDLs and LDLs HDLs transport cholesterol from the cells and tissue back to the liver. HDLs are considered ‘good’ as they take cholesterol out of cells and the blood thus helping to prevent excess cholesterol. HDLs also remove cholesterol deposited in the walls of blood vessels. The production of cholesterol takes place in every single cell in your body. Cholesterol is VITAL for cellular survival. Your liver is a manufacturing plant and one of the many ‘commodities’ it manufactures is cholesterol. If your cells need extra cholesterol, your liver is where the extra cholesterol is made. This cholesterol then has to get to the cells that require it. This is where LDLs come into the picture. LDLs are the 'taxis' that collect cholesterol from the liver and take it around the body, depositing it where it is needed. It is LDLs that are often referred to as ‘bad’ cholesterol. WHY DO LDL'S GET SUCH BAD PRESS? The transportive functionality of LDLs is absolutely vital to the health and survival of every cell in your body. If LDLs have such a vital role, why are they called ‘bad?’ The fact is, LDLs are not bad, per se. They only become a problem when they become entrenched in arterial walls, thereby clogging up your arteries. This is where the size and number of LDL particles matter. LDL particles exist in different sizes – large, fluffy, cotton-ball like molecules and small dense molecules. Studies are showing that people whose LDL particles are predominantly small and dense have a greater risk of coronary heart disease. Today we are learning to differentiate between LDL-C and LDL-P. LDL-C represents total cholesterol count (i.e. the cholesterol mass within the LDL particles), whereas LDL-P represents the number of LDL particles transporting the cholesterol in your body. Cholesterol shares its LDL 'taxi' with other fats, such as triglycerides and apolipoprotein Bs (ApoBs) (high levels of which represent a higher risk for cardiovascular disease than cholesterol). The more space these other fats take up, the less space is available for cholesterol, and so more LDL taxis will be required to transport the cholesterol from the liver where it is produced, to the cells where it is needed. This appears to be where the true problem lies. The higher your LDL-P levels (the number of LDL particles in your blood), the higher your triglyceride levels. Put more simply, scientists used to believe that the number of passengers in the 'taxi' (i.e the concentration of cholesterol in the LDL particle) is the driving factor in the development of heart disease. More recent studies suggest that it’s the number of 'taxis' on the road (LDL-P) that matters most. In other words, the more 'taxis' there are on the road, the more likely some will 'crash' into the fragile lining of the artery. If a person only has their cholesterol measured, and not their LDL particle number, they will be led to believe they are at a low risk of heart disease. HOW THIS IMPACTS THE RISK OF HEART DISEASE The importance of this in terms of heart disease risk is profound. When you go to a doctor to get your cholesterol levels tested, chances are it’s your total LDL and HDL cholesterol levels that are being tested. This tells you the concentration of cholesterol (passengers) inside the lipoproteins (taxis), which is not the driving factor behind plaque formation and heart disease. Instead, what should be measured is the number of LDL particles in your blood. Often, LDL cholesterol levels and LDL particle numbers are concordant (i.e when one is high, the other is high and vice versa). This is the most likely explanation for the association between LDL cholesterol and heart disease. But it is very possible to have a high number of LDL particles and normal/low cholesterol (e.g. 4 taxis each carrying 1 passenger will give you a low cholesterol of 4mmol/L, or 4 passengers, but a high LDL-P 4, or 4 taxis). If a person only has their cholesterol measured, and not their LDL particle number, they will be led to believe they are at a low risk of heart disease. Worse still, it is often the patients with high LDL particle number who present with some or more of the components of metabolic syndrome – such as abdominal obesity, hypertension, insulin resistance, high triglycerides and low HDL – and who are at higher risk of heart disease. Compare this to two taxis carrying 3 passengers each. This will mean a LDL- P of 2 (2 “taxis” on the road) but a high cholesterol level of 6mmol/L. More and more research is showing that patients with high LDL cholesterol (LDL-C) and low LDL particle number (LDL-P) are not at high risk of heart disease and in fact have a lower risk than patients with low LDL-C and low LDL-P. [1] LDL particles, as mentioned, are not a problem per se, but rather become a problem when they oxidise. All lipids (fats) can be damaged by exposure to heat and oxygen. Some LDLs are of very small size and can pass through artery walls. Free radicals can then cause oxidation and rancidity, triggering the inflammatory response. The important question to ask is “what is causing these LDLs to oxidise?” Consuming artificial, partially hydrogenated oils (trans fats), a diet high in refined sugars and refined carbohydrates, alcohol and smoking cigarettes will cause LDL particles to oxidise. When there is oxidation in the body, there tends to be free radical activity in the tissues, Consuming a diet high in antioxidants such as vitamins C and E helps to prevent oxidative free radical damage. The higher the number of LDL particles in your body, the higher your triglyceride levels will tend to be. If you have elevated triglycerides it is important to avoid a high carbohydrate diet, alcohol, sugary and refined carbohydrates, including sugar, honey, sugary drinks, and anything made with white refined flour. A diet low in carbohydrates and high in healthy fats, high fibre, non-starchy vegetables, seeds, nuts and with good-quality grass fed animal protein will help to reduce LDL particle number and optimise lipid levels. THE ISSUE WITH STATINS Many in the conventional medical establishment have hailed statins as a wonder drug. Statins are a class of medicines that are frequently used to lower blood cholesterol levels. They do this by blocking the action of a specific chemical in the liver that is necessary for making cholesterol. The main problem with this is the failure of the medical world to treat each person as unique and to instead adopt a ‘one size fits all approach.’ We know that cholesterol has many important functions in the body. Without cholesterol, for example, pregnenolone cannot be made. Pregnenolone is often referred to as the ‘master hormone’ as, without it, numerous other hormones cannot be synthesized. Cortisol is an important stress hormone, which is also a powerful anti-inflammatory hormone. If a person is going through a particularly stressful period, the liver may very well be called upon to make additional cholesterol. Statins interfere with this cholesterol-making process in the liver. All cholesterol-lowering drugs, such as statins, diminish hormone function. The most common side effects of statin drugs are loss of physical strength, sexual dysfunction, changes in mood and myopathy. Statins deplete the body of CoQ10 This is an enzyme necessary for the production of energy by every cell in the body. It is vital for good health, high energy levels, longevity and a good quality of life. The reduced form of CoQ10, ubiquinol, is a critical component of the production of your adenosine triphosphate molecules (ATP). Muscle cells need ATP like a car needs petrol. And guess what? Your heart is the most energy-demanding organ in the body. You can therefore understand how potentially devastating it can be to deplete your body of its main source of cellular energy. Thus when you read that statins can actually increase your risk of acute heart failure, this can be due to the depletion of CoQ10. If you are on a statin, make sure you discuss with a health care practitioner the need to take coenzyme Q10 as a supplement (in the form of ubiquinol if you are over 40, as in this form it will be far more effectively absorbed by your body). Ubiquinol actually helps keep your LDL levels reduced, as it’s an exceptionally potent antioxidant. LDL cholesterol only becomes a problem when it is oxidised. By reducing CoQ10 production in your body you are also removing the mechanism that keeps LDL cholesterol from doing harm in your body. Are statins ever beneficial? Yes. To summarise the scientific research on statins: The only section of the population that statins extend life in are men under the age of 80 who already have pre-existing heart disease. Statins have not been shown to extend lifespan in men under 80 without pre-existing heart disease, men over 80 with or without heart disease, and women of any age with or without disease. Statins do reduce the risk of cardiovascular events in all populations but these reductions are more modest than most assume and statins have been shown to cause a number of side effects. In fact, today the anti-inflammatory effects of statins on the vascular wall are more widely accepted. Randomised clinical trials have demonstrated that, further to their lipid-lowering properties, statins also reduce cardiovascular risk by exerting anti-inflammatory effects. [2] Since other cholesterol-lowering drugs have had little or no effect on heart disease, it is possibly the anti-inflammatory effects of statin drugs that are reducing this risk, particularly in light of the fact that chronic, low-grade inflammation is now accepted as being closely linked to all stages of atherosclerosis. However, due to the many side effects of statins and with our better understanding that it is not necessarily cholesterol by itself that leads to heart disease, but a process that begins with inflammation resulting in oxidation of cholesterol particles, it is important to incorporate a diet rich in anti-inflammatory foods. Other (often overlooked) factors implicated in heart disease Magnesium deficiency. This is a commonly overlooked risk factor for cardiovascular disease. Even a moderate magnesium deficiency can cause profound changes in how the heart functions. Because magnesium is essential for the healthy control of blood vessel function, blood pressure regulation and normal heart contractions, a magnesium deficiency increases the risk of conditions such as endothelial dysfunction, hypertension and cardiac arrhythmias. [3] Vitamin K2 deficiency. Vitamin K2 is as important as vitamin D for protecting your health. It is essential for activating enzymes involved in transporting calcium from your arterial walls to your bone. Calcium, vitamin K2, magnesium and vitamin D work together synergistically, and should ideally be taken in combination. According to top cardiologist, Dr Dennis Goodman, the importance of vitamin K2 in cardiovascular health is its ability to remove calcium from the lining of blood vessels. Calcium in the arteries is a key indicator of heart attack or stroke risk. In fact, measuring calcium build-up in the arteries is believed to be a better indicator of the likelihood of heart disease than measuring blood cholesterol levels. Vitamin D helps the body absorb calcium. Vitamin K2 (in the form of mk7) directs calcium out of the blood and to the bones. Taking too much calcium to prevent osteoporosis may increase your risk of myocardial infarction or heart attack, particularly if accompanied by a vitamin D and/or vitamin K deficiency. Elevated homocysteine. Studies of the general population have suggested that high homocysteine levels are associated with cardiovascular morbidity and mortality. [4] What traditional diet tells us Cultural studies provide the most relevant research for cholesterol and fat in the diet. Some of the fattiest diets in the world (such as in Austria, France, Greece and Switzerland) are low in processed, refined and hydrogenated fats and high in saturated fats such as butter, eggs, cream, cheeses and organic meats, yet these countries have lower rates of heart disease than the USA. In fact the diets of the countries that line the Mediterranean Sea have received a lot of attention lately. Saturated fats make up 70% of the caloric intake in these diets and yet traditionally they have some of the lowest rates of heart disease in the world.
- The Mediterranean Diet: Made Simple
One of the best studied diets in terms of cardiovascular health is the 'Mediterranean Diet'. This consists largely of fish, monounsaturated fats from olive oil, fruits, vegetables, whole grains, legumes, nuts, and moderate alcohol consumption. In fact, the Mediterranean diet crops up in magazines, health blogs and newspapers, almost on a daily basis. But what does the term actually mean and how can it help you maintain a healthier lifestyle? When we use the term 'diet', we are not referring to a crash weight-loss fad, as in, 'I lost 20 pounds on the Mediterranean Diet' Rather, we mean the nutritional choices that you make on a day-to-day basis. The Mediterranean diet involves a broad range of foods that have been traditionally eaten in such countries as Greece, Cyprus, Italy and Spain, during a time when little imported food existed and people lived off what was grown locally. This article will look at some of the staples of the Mediterranean diet and attempt to identify certain aspects that are particularly beneficial for cardio-protection as more and more research continues to highlight the potential for the Mediterranean diet to act as a key player in cardiovascular disease prevention. Historically, the people of the Mediterranean have been observed to live longer and suffer from less heart-related problems than populations in the rest of Europe. In the last century, this statistic has all but disappeared as diets across the continent as a whole have become much more homogenised and fast-food orientated, while lifestyles have become more sedentary. In fact, Greece now has one of the highest rates of childhood obesity anywhere in the world.1 Nevertheless, as the old way of life is slowly replaced by vacuum-packed ready meals and Big Macs, there is a constant build up of evidence that supports the Mediterranean diet's healthy claims. As a nutritional therapist, I should point out that any diet is only as good as the lifestyle that it is a part of. The people who traditionally benefited from this type of diet generally had physically active lifestyles, involving a lot of manual labour. The Mediterranean culture of long meals, shared with many family members is also a benefit as this relaxed pace of consumption is much better for our digestive systems. When we eat in silence, in front of the television, there is a tendency not to chew properly and to eat too quickly, giving our digestive systems a difficult job. The elements of the Mediterranean diet vary greatly, depending on geography and what is available at the time of year, but here are some of the essential elements to start incorporating into your nutrition planning: Olive oil Olives and olive oil are probably the first things that we all think of when the Mediterranean diet is mentioned. Olive oil is an excellent source of monounsaturated fats and polyphenols. I wrote in more detail about the benefits and risks of olive oil in a previous article, but as a general rule, try to use olive oil as a dressing, rather than a cooking oil, due to its low smoke point (instead cook with coconut oil) and make sure that it is stored in an airtight bottle to prevent oxidisation. Wholewheat pasta Wholewheat pasta is a source of complex starchy carbohydrates, which should make up around a third of our diet2. Starchy carbohydrates are an important source of energy and also contain fibre, iron and B vitamins. However, it is important to have an active lifestyle if consuming these foods in large amounts. If you find that your days are more sedentary than you would like, consider leaving the pasta out. Pulses Pulses include any edible seed that grows in a pod, so beans (baked, broad, runner, butter, kidney etc.), lentils, chickpeas, and garden peas are all part of this family. Pulses in general are a great source of protein and iron, especially important if you are a vegetarian. Like wholewheat pasta, they are a starchy food and so have plenty of fibre, which is often associated with reducing the risk of type-2 diabetes and heart disease. Around 80g of pulses count as one of your five-a-day. If consuming dried pulses, make sure you soak them as per the instructions on the packaging, in order to get rid of toxins that are often present. Tinned pulses will usually be safe to eat straight away, but always try to get hold of brands that have no added sugar or salt. Fish Fish, specifically oily fish, are a good source of lean protein, as well as supplying omega-3 fatty acids. There is a lot of concern today about the levels of mercury and other heavy metals in our fish stocks. Our seas are becoming more and more polluted, so use caution and check where your fish come from. Additionally, certain fish stocks are on the brink of collapse due to intensive fishing techniques and you may want to consider this when choosing what to buy in the supermarket. Try to consume as many of your vegetables in raw form as possible, as cooking allows many of the nutrients to escape. Fresh organic fruit and vegetables With new guidelines suggesting that we should be eating ten portions of fruit and vegetables every day, the Mediterranean diet, with its abundance of tomatoes, artichokes, beets, apples, figs, nuts, lemons etc, seems more and more like a fantastic healthy option. Don't worry so much about which fruit and veg are native to the Mediterranean, it is more beneficial to try and source organic foods, free of pesticides and chemicals. Try to consume as many of your vegetables in raw form as possible, as cooking allows many of the nutrients to escape. Fresh herbs Not only are fresh herbs full of nutrition, but they are also incredibly flavorsome and, as such, are a replacement for salt and sugar. If you can gradually wean yourself off the need for salt and sugar in your cooking, your taste buds will come to much prefer the more complex and delicate tastes of basil, bay leaf, thyme and the numerous other herbs used in the Mediterranean. Cheese and yoghurt Small amounts of cheese and yoghurt are common to the Mediterranean diet. They are a good source of calcium, which helps keep your bones strong and supports cardiovascular health. Some of the most common cheeses found in the Mediterranean are feta, halloumi, manchego, Parmesan, and ricotta. Over the next few weeks, I will be posting some of my favourite healthy Mediterranean recipes, so please check back soon, or sign up to my newsletter to make sure you don't miss out!
- How to Protect Your Heart
Since altering your lifestyle, diet and nutrition are the most important ways to achieve a good quality of life, here are some tips for how you can be proactive in boosting your heart health without the use of medication. Reduce grains and sugars in your diet. Look out for upcoming articles on how to reduce your dependence on sugar without sacrificing the taste. Consume as much of your food in raw form as possible, especially fruit and vegetables. Make sure that you are getting plenty of high-quality omega-3 fatty acids in your diet. Research shows that as little as 500mg of omega 3 per day can help improve total cholesterol and triglyceride levels and will likely increase your 'good' HDL levels. Replace harmful vegetable oils and trans fats with healthy saturated fats, like olive oil, coconut oil, butter, avocado and eggs. Remember to only use olive oil cold and favour coconut oil for cooking and baking. Include fermented foods in your daily diet, such as yoghurt, sauerkraut or pickles. This will help to optimise your intestinal flora as well as boost your overall immunity. Optimise vitamin D levels. Vitamin D helps prevent the formation of arterial plaque. The best way to get your body's daily quota of vitamin D is from 15 minutes of direct sunlight a day, but you can also include foods such as oily fish, eggs and cheese, which are all rich in this vital nutrient. Exercise regularly. Current research shows that High-Intensity Interval Training (HIIT) is the most effective form of cardiovascular exercise as a mere fifteen minutes will cause the heart to keep working at an elevated level for the rest of the day. Avoid smoking and excessive alcohol consumption. Get plenty of high-quality restorative sleep. Practice regular stress-management techniques.
- Statins: Analysing The Media Hype
Statins are the most widely prescribed drugs in the world today, which means the next time you visit your doctor, depending on your symptoms, he may very well discuss them with you. However, if you read the tsunami of scientific research on statins, these drugs are surrounded by controversy, with some studies hailing them as life-savers and others warning against their use. There have been several articles in the mainstream media throughout the UK, warning that “thousands of Britons are dying from heart attacks and strokes after being scared off statins by warnings of non-existent side effects." If you are one of many, now considering rushing to your GP to get a prescription for a statin drug, fearing that, having been 'scared off' statins yourself, you are going to join the thousands of Britons who are dying, I am going to attempt to clarify the media hype for you. One thing is certain about statins: for every drop of scientific evidence that statins are safe and effective, there is a deluge of evidence that warns of their side effects. The Misrepresentation of Statins London cardiologist Dr Aseem Malhotra goes as far as saying “I fear the misrepresentation of research on statins – both in terms of benefits and harms – will be one of the biggest cons and scandals in the history of medicine.” Let’s consider one news headline: “False scare on statins causes thousands to die.” Statements like this imply that thousands of Britons are dying because they are not on a statin. Yet we know from numerous recent scientific studies that over 50% of heart attacks are not related to cholesterol levels. We also know that there are numerous other independent risk factors implicated in heart disease, such as diabetes and pre-diabetes, [1] metabolic syndrome, [2] low levels of serum cholesterol in the elderly, [3] elevated homocysteine [4] and obesity. [5] So, is there any proof that these deaths are caused by a failure to take a statin drug? The SIDE EFFECTS of Statins A major study conducted over three years, which looked at lowering cholesterol in more than ten thousand patients in the UK, Ireland and the Nordic regions, found that patients reported more side effects when taking the drug. In light of the evidence of the side effects of statins that has accumulated over the past decades, it is difficult to understand how the finding of this study has led to the assertion that there are “non-existent side effects,” to taking statins. This reference to “non-existent side effects” is an example, I believe, of what Dr Malhotra is referring to about the misrepresentation of research on statins. There is a huge amount of scientific evidence on the side-effects of statin use and it is ever-increasing. Click here to access 514 abstracts of research on statin induced pathologies. More important still, is the evidence from patients who, having experienced one or more side effects whilst taking statins, report feeling better as soon as they stop. The main author of the study, quoted at the top of this article, which was published in The Lancet, attributes these side effects to ‘the nocebo effect,’ i.e “the symptoms of muscle pain and weakness are not caused by the drugs themselves … but are a psychosomatic response,” he explains. Many patients who suffer, or have suffered, the debilitating side effects of statin drugs will beg to differ. In fact, in an article in theWorld Journal of Cardiology, entitled “Cholesterol Confusion and Statin Controversy,” the point is made that in “the largest statin survey ever conducted, the National Lipid Association observed that roughly 30% of statin patients reported experiencing muscle pain and weakness and 57% of surveyed patients reported stopping the drug due to side effects. [6] This article goes on to point out that the “incidence of muscular aches and weakness in statin trials is highly variable, and real world experiences may differ from clinical trial reports.” This may very well explain the nocebo effect reported by the author of this study. The 2015 article in the World Journal of Cardiology evaluated numerous studies on cholesterol and statins, stating that the role of blood cholesterol levels in coronary heart disease (CHD) and the true effect of cholesterol-lowering statin drugs are debatable. In particular, whether statins actually decrease cardiac mortality and increase life expectancy is controversial. Currently the Mediterranean diet model has been shown to prolong life and reduce the risk of diabetes, cancer and CHD. This article states that early statin trials have been flawed, mortality benefits of statins are inconsistent, statin drugs have unintended consequences, and concludes that “the global prevalence of CHD, despite worldwide statin usage and cholesterol lowering campaigns, has reached pandemic proportions.” What I find most concerning is that, despite the growing evidence that cholesterol is not the primary cause of heart disease, the pharmaceutical industry is still aggressively marketing statins. Coronary heart disease is an extremely complex malady and the expectation that it could be prevented or eliminated by simply reducing cholesterol, appears unfounded. It is time to concede the anomalies of the cholesterol hypothesis and refocus our efforts on the proven benefits of a healthy lifestyle, incorporating a Mediterranean style diet, to prevent CHD. This study has been published in The Lancet and was funded by the drug firm, Pfizer, which manufactures statins. Previous related studies in The Lancet have elicited headlines such as “Lancet study on statins was fundamentally flawed,” “ Statins: Flawed Studies, False Advertising and Lack of Transparency” and “Statin side effects are more troubling than a new paper admits.” What is concerning is that, despite the growing evidence that cholesterol is not the primary cause of heart disease, the pharmaceutical industry is still aggressively marketing statins.
- Healthy Fats: Choosing Your Oils
There are several important health and nutrition factors to take into consideration when choosing oils for cooking and dressing: Make-Up: Oils primarily fall into one of these categories: saturated, monounsaturated, or polyunsaturated. Some oils with more polyunsaturated fatty acid components (PUFAs) are less stable than saturated or monounsaturated oils and more susceptible to oxidative damage, which makes them more harmful to our bodies and more inflammatory when used in cooking. Smoke Point: The smoke point of an oil is the temperature at which it starts to burn and smoke. Know the smoke point of the oils you use when cooking. When oils cook beyond their smoke point, they not only mar the taste of your food, but also release free radicals and a substance called acrolein, the chemical that gives burnt foods their acrid flavour and aroma. Non-Refined vs. Refined Oils: Non-refined oils tend to have higher antioxidant properties, compared to refined oils, and do not go through the same processing and chemical alteration. Guidelines for choosing the correct cooking oil When cooking on high heat, saturated fats are the most stable and will not oxidise. These include: Animal based, preferably grass-fed organic Ghee (clarified butter) Goose and duck fat Butter Lard Chicken fat Plant-based: Coconut Oil Palm oil (sustainably sourced) When cooking on high heat, saturated fats are the most stable and will not oxidise. If using low heat or if unheated, use moderately stable monounsaturated fats Avocado oil Macadamia nut oil Olive oil Sesame oil Do not heat these polyunsaturated fats as they are the least stable of the fats and are easily damaged by heat: Flaxseed oil Nut oils "Back in the MI (myocardial infarction) free days before 1920, the fats were butter and lard and I think that we would all benefit from the kind of diet that we had at a time when no one had ever heard the word corn oil.” - Dr. Dudley White speaking at an American Heart Association fundraiser in 1956. Oils to avoid entirely Vegetable Oils - are highly processed polyunsaturated fats. They are pro-inflammatory, impairing proper cell function. Vegetable oils may sound healthy but they require industrial processes using toxic chemicals like hexane and bleaching agents to help extraction. Even organic vegetable oils undergo tremendous processing. Exposed to heat, vegetable oils oxidise easily, resulting in a toxic food. Oils, like soy, corn, canola, sunflower, rice bran, safflower and grape seed, increase inflammation in the body. These polyunsaturated vegetable oils, especially when heated, damage your metabolic function, gene expression, hormone functions and your cells (evening primrose and hemp oils are exceptions as they function as anti-inflammatories). Canola oil Corn oil Cottonseed oil Grape-seed oil Safflower oil Soybean oil Sunflower oil Vegetable oil Artificial Trans Fats - promote systemic inflammation. They increase the risk of obesity, heart disease and cancer. Hydrogenated or partially hydrogenated oils Margarine Vegetable shortening Other Oils - These are highly processed fats, which are pro-inflammatory and impair proper cell function: Peanut oil Rice bran oil “Trans-fat free” buttery spreads Vegetable oils may sound healthy but they require industrial processes using toxic chemicals like hexane and bleaching agents to help extraction. Omega 3 and Omega 6 Fatty Acids A crucial thing to be aware of is the ratio of omega-3 to omega-6 fatty acids in our diet. These are referred to as essential fatty acids as they are essential to our health and nutritional well being. Unfortunately, our bodies do not produce essential fatty acids and so we must consume them as part of a healthy diet. The rise in the consumption of vegetable oils (found in all processed foods) and the grain-feeding of cattle and poultry has altered the typical omega-3 to omega-6 ratios. Humans have evolved to eat a diet with an omega-6 to omega-3 ratio of about 1:1. Modern Western diets contain a ratio of 15:1 to 17:1. Oily fish, flax seeds and chia seeds, walnuts and walnut oil and cod liver oil are all good sources of omega-3s. Elevated omega-6 intakes are associated with an increase in inflammatory diseases such as cardiovascular disease, type-2 diabetes, obesity, metabolic syndrome, irritable bowel syndrome, inflammatory bowel disease, muscular degeneration, rheumatoid arthritis, asthma, cancer, autoimmune and psychiatric disorders. In particular, there is a high association between a rising intake of omega-6 and increased mortality from heart disease. Saturated fats The Diet-Heart Hypothesis, first proposed by Ancel Keys, has little evidence to support it, yet it has managed to have a huge influence on dietary and nutrition guidelines around the world. Heart disease was rare in the 1900’s when our diets were much higher in animal fats. The elevated triglycerides in the blood linked to heart disease do not come from dietary fats, but are produced in the liver from excess sugars that come from carbohydrates, such as refined sugars and white flour and from fructose. What is contributing to heart disease is the excess consumption of vegetable oils, hydrogenated fats and refined sugars in our modern diet. “The greatest scientific deception of this century, perhaps of any century.” - George Mann, American scientist, criticising the Diet-Heart Hypothesis: the idea that high-cholesterol foods cause heart disease. Coconut oil Coconut oil is one of the best fats to cook with, as it does not denature at high heats. Current research has exposed the once highly regarded 'high carbohydrate, low fat, low cholesterol' diets as harmful to our health and saturated fats as beneficial. Coconut oil is a safe, nutritious, anti-inflammatory food. It is also a great source of fuel for the body. The medium chain triglycerides (MCTs) found in coconut oil do not need bile acids to break down. They are easily absorbed and in the liver they convert to ketones. The brain uses glucose as it’s main energy source, but ketones provide another great source. Even better, unlike glucose, which requires insulin to get into the cells, ketones do not rely on insulin and are an alternative source of fuel for brain (and other) cells that have become insulin resistant. Coconut oil is rich in lauric acid, a fatty acid that is anti-fungal, anti-bacterial and ant-viral. Other health benefits of coconut oil include: promoting heart health, supporting the immune system, supporting a healthy metabolism, keeping skin healthy and youthful looking, providing an immediate source of energy (from the MCTs) and supporting proper functioning of the thyroid gland. The bottom line is that populations that consume large amounts of coconut do not have high levels of heart disease and are generally in excellent health. [1] The MCTs in coconut oil can also reduce appetite and increase fat burning. Many studies are finding that these types of fats have benefits for people with Altzheimer’s. Olive Oil Extra-virgin olive oil is a very good monounsaturated fat, well known for its health benefits. It is also the oil of preference in healthful diets, such as all Mediterranean-style diets. [2] However due to its chemical structure and the large amount of unsaturated fats, heating extra virgin olive oil makes it susceptible to oxidative damage. It is therefore best used cold, typically drizzled on salads and other foods. And know that even when used cold, it is extremely perishable as it goes rancid fairly quickly, due to the chlorophyll contained in it. To protect the oil, keep it in a cool, dark place; purchase smaller bottles to ensure freshness and immediately replace the cap after each pour. Extra virgin olive oil oxidises every time it is exposed to air and/or light. In fact for these reasons, some people prefer to use the almost tasteless, semi-refined olive oil rather than extra-virgin olive oil. Extra virgin olive oil is nevertheless full of health benefits and contains polyphenols, which act as antioxidants, reducing oxidative stress throughout the body. High fat foods full of nutrition Avocados are a tasty, nutritious, high-fat food that are packed full of healthy monounsaturated fats (MUFAs), as well as nearly twenty vitamins and minerals. Avocados taste great sliced up in a salad at lunchtime, mashed and spread over toast as part of a healthy breakfast, or made into a tasty guacamole. Cheese is a great source of calcium and is rich in protein. Like other high-fat dairy products, it contains powerful fatty acids linked to all sorts of health and nutrition benefits, including reduced risk of type-2 diabetes. (I always recommend organic when consuming meat or diary). Dark chocolate [3] is high in fat, but also loaded with nutrients and antioxidants. Studies show it is effective at improving cardiovascular health and improving brain health. Just make sure you are choosing good quality dark chocolate with at least 70% cocoa. Whole eggs used to be considered unhealthy because the yolks are high in cholesterol. However, if you are not allergic to eggs (and many people are), they are now considered to be one of the most nutrient-dense foods and a healthy way to start the day. Fatty fish, such as sardines and mackerel, are loaded with important nutrients and are one of the best sources of the all-important omega-3s. Nuts are incredibly healthy and nutritious. They are among the best sources of plant-based protein. They are also a rich source of vitamin E, magnesium and healthy fats. Many nuts, particularly walnuts, are a good source of omega-3s. Chia seeds are another good source of omega-3s and are loaded with fibre and minerals. Full fat yoghurt is a good source of probiotic bacteria that have powerful effects on your health. Make sure you choose real, full-fat and read the label as many yoghurts are low in fat and loaded with refined sugar.

As part of my Healthy Fats series, here are some high-fat foods that are full of nutrition and should form part of your balanced, healthy diet. Please take a look at my recipes page for ideas on incorporating these foods into your meals. Avocados are a tasty, nutritious, high-fat food that are packed full of healthy monounsaturated fats (MUFAs), as well as nearly twenty vitamins and minerals. Avocados taste great sliced up in a salad at lunchtime, mashed and spread over toast as part of a healthy breakfast, or made into a tasty guacamole. Cheese is a great source of calcium and is rich in protein. Like other high-fat dairy products, it contains powerful fatty acids linked to all sorts of health and nutrition benefits, including reduced risk of type-2 diabetes. (I always recommend organic when consuming meat or diary). Dark chocolate (1) is high in fat, but also loaded with nutrients and antioxidants. Studies show it is effective at improving cardiovascular health and improving brain health. Just make sure you are choosing good quality dark chocolate with at least 70% cocoa. Whole eggs used to be considered unhealthy because the yolks are high in cholesterol. However, if you are not allergic to eggs (and many people are), they are now considered to be one of the most nutrient-dense foods and a healthy way to start the day. Fatty fish, such as sardines and mackerel, are loaded with important nutrients and are one of the best sources of the all-important omega-3s. Nuts are incredibly healthy and nutritious. They are among the best sources of plant-based protein. They are also a rich source of vitamin E, magnesium and healthy fats. Many nuts, particularly walnuts, are a good source of omega-3s. Chia seeds are another good source of omega-3s and are loaded with fibre and minerals. Full fat yoghurt is a good source of probiotic bacteria that have powerful effects on your health. Make sure you choose real, full-fat and read the label as many yoghurts are low in fat and loaded with refined sugar. 1 Buijsse B, Feskens E, Kok F, Kromhout D (2006) Cocoa intake, blood pressure, and cardiovascular mortality: the Zutphen Elderly Study.

- How Healthy Is Your Heart?
Take heart: nine out of ten strokes can be prevented. Did you know, in the United States, someone has a heart attack every 34 seconds and every minute someone dies from a heart-related incident? Plus, around 50% of people who have a heart attack, have normal lipid (cholesterol) levels? And did you know that heart disease is, in most cases, preventable? The healthy heart quiz Take this quiz to understand how healthy your heart is. Score 1 for every YES answer. The ideal score is 0! Is your blood pressure above 140/90? Is your resting pulse above 80? Is your cholesterol above 5.5? Is your homocysteine level above 9? (Ask your GP for this test if you have never been tested.) Do you get out of breath climbing up stairs or inclines? Do you sometimes get chest pains? Do you smoke more than 5 cigarettes a day? Do you exercise less than twice a week? Are you overweight? Do you have cardiovascular disease? Do any of your immediate family suffer from cardiovascular disease or high cholesterol? Do you eat LESS than three servings of fruit and vegetables most days? Do you rarely take vitamin supplements? Do you consider your lifestyle stressful? Do you eat fried food, meat or other high fat foods most days? Less than 4: your score is low but address those questions to which you answered yes. 5 or more: You may be at high risk of cardiovascular illness. Take action now to change your diet and lifestyle. Check my websitE for guidelines, help and advice on how to improve your cardiovascular health. Backed up with the necessary lifestyle changes, many people find rapid improvements in cholesterol, blood pressure and other risk indicators. Risk factors for Cardiovascular Disease In assessing your risk for cardiovascular disease, the following are the most important markers to consider. Discuss having a blood test with your GP that includes all of these, particularly homocysteine, which is not always part of a regular blood screen. You are at a higher risk of heart disease if you have any 3 of the following 5: Increased waist circumference (> 35” women, > 40” men). Increased blood pressure (> 130/85). Increased fasting blood sugar (> 100 mg/dl USA, > 5.55 mmol/L UK). Increased triglycerides (> 150 USA, > 1.69 mg/dl UK). Decreased HDL cholesterol (< 50 women, < 40 men USA, < 1mmol/L UK). Increased homocysteine levels. Just a slightly raised level can increase your risk of a heart attack. In fact published literature indicates that homocysteine is an independent cardiovascular risk factor modifiable by nutrition (i.e. right amount of vitamin Bs) and exercise.[1] Increased CRP. C Reactive Protein is a marker of inflammation in the body and more and more experts who study blood vessels, plaque, and heart attacks in minute detail have been developing an inflammatory explanation for heart attacks. If there is a family history of cardiovascular disease in your family, it is possible, and in fact in the U.K. becoming more common, to request a LDL -P test. Remember, no matter how long you have travelled in the wrong direction, you can always turn around.
- Separating Fat from Fiction
The UK is officially the fattest nation in Europe and levels are fast catching up to those in USA. Many top doctors, cardiologists, nutritional therapists and functional medicine practitioners are blaming this obesity epidemic on current dietary guidelines in the UK and USA. What we know as a fact is that, since we began vilifying fat, more than 50 years ago, low-fat, fat-free diets have been accompanied by an increase in heart disease, obesity, diabetes and numerous other chronic conditions. Today's blog will attempt to summarise the current views of top functional medicine practitioners and many cardiologists (supported by scientific, epidemiological studies). I will highlight the true risk factors of, not only heart disease, but also many other chronic conditions. After many years spent as a leading NHS cardiologist, Dr Aseem Malhotra explains, in an interview with Dr Mark Hyman, that he started noticing that most heart attack patients he was treating were obese. He was also seeing an increasing number of patients with chronic diseases and multiple co-morbidities (additional illnesses). More alarmingly, in light of our current obsession with cholesterol, Dr Malhotra was seeing numerous heart attack patients whose cholesterol levels were completely normal. Many of these patients followed recommended dietary guidelines and therefore assumed that their diets were fine. Dr Malhotra decided it was time to ‘stop jumping into the river to save drowning patients, but rather to get them to stop jumping into the river in the first place’. In other words it was time to reassess root causes. ...it was time to stop jumping into the river to save drowning patients, but rather to get them to stop jumping into the river in the first place. After studying the science and numerous epidemiological studies, Dr Malhotra concluded that this low fat message was actually causing harm. The food industry had been responding to this ‘low fat is good for you’ message by adding sugar to processed food and marketing it as healthy. We know today that there are numerous studies coming out which implicate sugar as an independent risk factor, not only for heart disease, but also for most chronic diseases. He concluded that it is much more important to consider triglyceride and HDL levels than LDL (remember – HDL is the good ‘taxi driver’ that goes around mopping up deposited cholesterol from arterial walls). More and more data is pointing to the fact that low HDL, high triglycerides and markers of metabolic syndrome** are important risk factors for cardiovascular disease. 1, 2 In fact, pre-diabetes and diabetes have been shown to be higher risk factors for heart disease than LDL and cholesterol. 3 We have an epidemic of misinformation around fat, sugar and statins: More and more studies are linking the saturated fatty acids found in full-fat dairy, yoghurt and cheese to a reduction in the risk of type 2 diabetes and heart disease. This could explain the 'French Paradox' that, in Europe, the French have the highest consumption of saturated fat and the lowest cardiovascular mortality rates. Dietary guidelines are still sticking to the hypothesis that saturated fat increases total cholesterol and LDL levels, and that they are risk factors for cardiovascular disease, despite accumulating data against this hypothesis. In fact the Big Fat Fraud has become so ingrained in us that most people still panic when they see that their cholesterol and LDL levels have gone up. There are hidden dangers of statins your doctor is possibly not telling you about – such as an increased risk of developing type 2 diabetes and mitochondria damage. Statins are the most prescribed and lucrative pharmaceutical drug today but who actually benefits from statins? As we grow older, there is an inverse association with cholesterol levels. Over the age of 60, higher cholesterol serum levels lower the risk of cardiovascular disease. 4 Should we therefore be using statins in older patients? Please take a look at my article weighing up the [pros and cons of statins][0] and analysing recent scientific research on their true benefits and dangers. Different calories have different metabolic effects on the body. 500 calories of extra virgin olive oil per day as part of a healthy diet reduces the risk of heart attack and stroke. 150 calories from one can of soda increases your risk of type 2 diabetes and heart disease. 5 Foods that have high fat have the least impact on glucose and insulin. Statins are the most prescribed and lucrative pharmaceutical drug today...

- Guidelines for an Anti-Inflammatory Diet
Inflammation is the common denominator in most chronic diseases. It accelerates ageing and if you have inflamed arteries they will grow a lot more plaque. An anti-inflammatory diet is aimed at lowering inflammation. These are the main guidelines: Consume adequate omega-3 fatty acids. One of the key sources of omega-3 fatty acids is oily fish (as opposed to white fish like cod or sole). Oily fish include anchovies, sardines, pilchards, herring, mackerel, trout, salmon, and tuna. Interestingly, if like me you have been limiting your fish intake due to concerns about mercury, it turns out that these fish all have higher levels of selenium than mercury. The relevance of this is that selenium consistently and predictably counteracts the adverse effects of mercury exposure.1 Most ocean fish contain more selenium than mercury. However the selenium status of freshwater fish is more variable and, without the selenium health benefit, the high mercury, low selenium ratio may cause harm to consumers. Also, today farmed salmon has become one of the most toxic foods in the world. Furthermore, salmon labelled ‘Atlantic salmon’ typically comes from fish farms. Look for Alaskan salmon, which is not allowed to be farmed, and is a powerhouse of nutrition. If you are concerned about your mercury levels, you may wish to consider taking natural mercury chelators such as zeolite (green clay), chlorella and fermented vegetables. Oily fish remain one of the best sources of animal-based omega-3 fats EPA and DHA. Aim for two servings (4oz or 113g each) of fatty fish per week. Choose healthy fats. Replace vegetable oils and trans–fats with healthy fats. Adding more healthy fats, olive oil and nuts is good for your arteries and decreases the risk of heart attack and stroke. Increase vegetables and fruit intake. Aim to consume between 5-9 servings of fruit and vegetables per day. Go for colour. Deeply coloured fruits and vegetables have high levels of protective phytonutrients. Click here to view the BANT wellness plate. Choose whole-grain carbohydrates and limit portion sizes. Aim for 25g-30g of fibre a day, choosing whole grains (quinoa, brown rice), fruit and vegetables and reducing your intake of refined carbohydrates (anything with flour and/or sugar). Get most of your protein from plant sources such as legumes, nuts and seeds. If choosing animal protein, ensure it is lean and clean. Avoid processed, commercialised, hormone and pesticide-enriched protein and choose free-range, organic poultry and chicken. If going for a steak, it should be a lean cut such as sirloin. And if possible, buy organic, grass-fed, not hormone-fed. Spice it up. Fabulous flavours. People don’t realise how important it is to have flavour in food. Herbs and spices are the most anti-inflammatory of all foods. Include garlic, turmeric, ginger, curry spices, chilli, cumin, cayenne, rosemary, oregano and other Italian herbs to your food. They are very anti-inflammatory, anti-aging and rev up your metabolism. Beneficial beverages. Many people get as much as 25% of their calories from drinking sugar. Beneficial beverages would include having a protein smoothie for breakfast (see recipes). Drink more clean water, water that comes from reverse osmosis or water from glass (BPA free) bottles rather than plastic. Green tea. One or two cups of coffee a day and a glass of red wine with dinner, provided you are able to limit it. If not, avoid. Red wine does help digestion, blood sugar and cholesterol. Enjoy dark chocolate (70% +) as a treat. Dark chocolate (28 grams a day) is great for heart and brain. Exercise. Fitness is important. Fitness is powerfully connected to whether you grow plaque. Magnesium. 70% of Americans are magnesium deficient. Magnesium helps blood pressure and blood sugar. Symptoms of magnesium deficiency include muscle cramps, constipation, migraines and palpitations. Magnesium is found in nuts, seeds, beans and leafy green vegetables. Most people who are magnesium deficient need about 400 milligrams of protein-bound magnesium so it is easier on the stomach and better absorbed. Click here to view some excellent sources of magnesium. Vitamin D. Vitamin D is very important for heart health. More and more people are becoming vitamin D deficient. Stress. It is not always possible to avoid stress but it is possible to manage it. Stress ages your heart, shrinks your brain and causes arteries to grow plaque. It can contribute to loss of muscle and bone mass and makes it hard to shift excess weight. Some key steps to managing stress are to feel loved and supported, to build connections in your life, get enough sleep, and have some peace and calm every day. It is also essential to find some relaxation time, meditation time, prayer time and get a good work out.

- The Benefits of Dietary and Lifestyle Changes
Poor diet contributes to more illness and premature death than physical inactivity, smoking and alcohol combined. Diet is key. More and more data proves that even if you exercise and have a normal body weight, if you eat ‘junk’ you are increasing your risk of adverse health consequences. Here are some nutrition, diet and lifestyle tips, based on the current science: Focus on dietary changes aimed at good health. Weight loss will follow. Do not focus on weight loss. Reduce sugar and refined carbohydrate consumption and increase saturated fats. This will help increase HDL levels and drive down triglycerides and total cholesterol. The good news is that it takes decades to develop heart disease but it can take months to start benefiting from dietary changes. In fact, some benefits start within weeks. Start by increasing your intake of fatty fish (sardines, anchovy, salmon, mackerel) and adding 1 to 2 portions of nuts weekly to your diet. Remember food is medicine. Stay away from the harmful trans fats - artery-clogging fats found in fried foods, biscuits, pastries, French fries etc. These increase levels of LDL, lower levels of HDL and increase risk of diabetes 2 and heart disease. Remember FOOD is also POISON. Exercise more – exercise helps raise HDL levels. Stress less. Stress is a well-accepted risk for heart attacks. Look out for upcoming blogs on stress management on my website.
- Happy Guilt-Free Easter!
As we start the Easter Weekend, many of you may be concerned that with all the wonderful chocolates and treats around, your good intentions not to indulge will gradually be melted away by temptation. However, this is not a time to feel guilty. This is a time to get together with family and friends. It's a time for Easter-egg hunts and maintaining long-observed family traditions. Remember the 80/20 rule: What you do for 80% of the time is way more important than what you do for the remaining 20%. The 80/20 rule allows you to be realistic. No one can eat a perfectly healthy diet 100% of the time. Applying the 80/20 rule to your diet for longterm success brings more happiness than the suffering imposed by rigid, limiting diets. The 80/20 rule means that on birthdays/holidays and special occasions - you can indulge without having to feel that you've completely ambushed your healthy lifestyle. It means that you are forming lifelong habits rather than unsustainable crash diets. It means that you do not have to be perfect 100% of the time. Balance is key and eating healthily most of the time gives you the wiggle room that every sane person needs to let their hair down now and again. Finally - remember laughter, fun, friends, togetherness, relaxing and not stressing about what you are eating will bring you way more health benefits than fretting over an easter egg or two. Please head on over to TT's Tips for some more practical ideas on staying healthy this Easter
- Tips for a Happy, Healthier Easter
Here are some practical tips to help you have a happy, healthier Easter! Where possible, choose dark chocolate over milk. Dark chocolate is a powerful source of antioxidants and actually improves several risk factors for heart disease. If you are having hot cross buns, enjoy them in moderation. Try to avoid those made with white flour and refined sugars. If you have time, consider baking your own with wholemeal flour and substitute refined sugar with date sugar or, even better, stevia (a low calorie, natural substance, derived from the South American stevia plant). Try to stay physically active over the Easter break. If you don't have time to get to the gym, try taking a walk after your main meal. Resurrect yourself - It's not the occasional indulgences (like a chocolate egg at Easter) that affects your health level, but rather how you bounce back. Come Tuesday morning, it's time to kick your healthy routine back into action! Give any surplus eggs to friends or family to avoid temptation.

- Cholesterol & Fat: Friend Or Foe?
Many people believe that eating foods with cholesterol and fat, especially saturated fat, causes heart attacks; but is this really true? One of the biggest myths that nutritional therapists come across every day is that dietary fat and cholesterol levels are the number one enemy and that heart attacks are caused by a high-fat diet. Although study after study after study often shows no link between total fat, saturated fat, dietary cholesterol, and heart disease; the media, most doctors and traditional health advisors are still recommending that we cut all fat and cholesterol from our diet Most of us have heard of cholesterol, triglycerides, HDL and LDL, yet many do not have a proper understanding of their function. This post will aim to explain them in as simple a manner as possible, to enable you to better understand your own blood test results. What are Lipoproteins? Lipoproteins are like microscopic taxi drivers that shuttle cholesterol and triglyceride (fat) molecules through the blood stream from place to place. LDLs (Low-Density Lipoproteins) are the smaller cousins of HDLs (High-Density Lipoproteins). LDLs are responsible for delivering cholesterol to the cells. Sometimes the LDL does not make it to its destination and instead sticks to the walls of your arteries. HDLs carry excess cholesterol back to the liver, thus preventing excess LDL cholesterol from sticking to the walls of your arteries. What are Triglycerides? Triglycerides are fat molecules in the blood. They are the main form of fat in the body. The fat contained in the food we eat consists of large molecules, which the body breaks down into triglycerides. Any extra protein, fats or carbs in the food we eat, that does not get used up by the body right away, is converted into triglycerides. Like cholesterol, triglycerides are transported around by lipoproteins. When we think of excess fat developing around the hips or belly, we are thinking of triglycerides. High triglyceride levels can increase the risk of heart disease. What is Cholesterol? Cholesterol is a wax-like fatty substance, found in almost every cell of our bodies. About 75% of cholesterol is made in our liver. In other words, very little of the cholesterol measured in the blood comes from what we eat. Cholesterol is so vital to our health, that our bodies actually make it. If we had no cholesterol in the body we would be dead. Cholesterol is important for cell structure, bone structure, muscles, hormones, brain function (25% of cholesterol is found in the brain) and nerve endings. All steroid hormones in the body (estrogen, progesterone, testosterone, pregnenolone etc.) are made from cholesterol. In your brain and nerve tissues, cholesterol is required for the formation of the myelin sheath, a fatty material that surrounds long portions of nerve fibres. Cholesterol is necessary to produce vitamin D. Bile salts, which break down carbohydrates, fats and protein are created with cholesterol. Mothers' breast milk is 60% cholesterol. It is necessary for the development of the baby’s brain and nervous system. When damage and inflammation occur in blood vessels, it is cholesterol which rushes to the site to repair the damage. Cholesterol acts as an antioxidant to protect cells and tissues from free radical damage. It is clear from a nutritional standpoint, that a fat-free diet cannot possibly promote optimal health. Cholesterol is made up of carbon molecules, hydrogen molecules and oxygen. There is no good or bad version of this. It is also important to understand that HDL is not 'good' cholesterol and LDL is not 'bad' cholesterol. They are not cholesterol at all; they are lipoproteins (there are, by the way, other lipoproteins such as VLDL – Very Low Density Lipoproteins). Lipoproteins are taxi drivers that cart cholesterol and triglycerides (as well as proteins and phospholipids) around the blood stream. There is no such thing as 'good' cholesterol and 'bad' cholesterol. Cholesterol is cholesterol! The reason LDL is considered ‘bad’ is because of its low density. It is smaller and more capable of getting stuck in arteries. HDL is, as the name suggests, high density and is considered good because its function is to ‘mop up’ the deposited excess cholesterol and take it back to the liver. This is where size matters: the bigger, the better. The smaller the particle, the more likely it is to make its way into the arterial wall and get stuck. Once stuck it has a greater chance of being a risk for heart disease. Not everyone with a high level of LDL suffers a heart attack or stroke. Only 50% of people with coronary artery disease have high levels of LDL. People with high VLDL levels have a greater risk of heart disease. Thus, when it comes to testing (which will be discussed later in the month), the particle size of the LDL is a greater indication of risk for cardiovascular disease. If you would like to learn about LDL and HDL in more detail, this is a great website which clearly explains their role in our health. Our bodies make cholesterol. Statins prevent the body from producing the cholesterol it is designed to make. Statins literally stop one of our fundamental processes from functioning. “Cholesterol in food has no impact on cholesterol in the blood and we have known that all along.” - Ancel Keys TT's Top Tips On Health, Cholesterol & Fat Increase omega-3 fatty acids. Eat anti-inflammatory foods like cold-water fish such as sardines, salmon, herring as well as flaxseed and even seaweed. Healthy fats benefit your heart by improving your overall cholesterol profile. Essential fats reduce inflammation. They decrease triglycerides. They also decrease the smaller more dangerous lipoprotein particles that contribute to heart disease by converting them into light, fluffy, safe bigger particles. Avoid fried food. Eat plenty of fresh fruit and vegetables to ensure your diet is rich in antioxidants. Free radicals can damage artery walls, enabling plaque to form in them. Antioxidants disarm the free radicals and so stop them causing damage. Stay fit. No smoking. Maintain a healthy weight. Avoid prolonged periods of stress. Know your blood pressure and have your blood lipid levels checked every 5 years.

- Cardiovascular Month
Take heart: Nine out of ten strokes can be prevented. Did you know, in the United States, someone has a heart attack every 34 seconds and every minute someone dies from a heart-related incident? Did you know that around 50% of people who have a heart attack, have normal lipid (cholesterol) levels? And did you know that heart disease is, in most cases, preventable? April is Cardiovascular Month on my website. I will be posting information and advice about healthy hearts on my blog throughout the month. I will explain how our understanding of the causes of heart disease has shifted from fats and cholesterol to metabolic syndrome, insulin and inflammation. I will discuss ‘The Big Fat Fraud’ and how fats came to be public enemy number one. We now know that healthy fats form a crucial part of a balanced diet – but are ALL fats healthy? Which fats are safe to cook with? When we have blood tests to assess cardiovascular health, which tests should we be asking for? I will explain the difference between HDL, LDL, VLDL and triglycerides to enable you to better understand your OWN blood test results and what they mean. How many of you are on statins? How many of you on statins are aware of the numerous long-term adverse side effects of statin use? Government guidelines are causing many people to be put on statins, who have cholesterol levels considered perfectly healthy in the field of Functional Medicine. I will explain the very important role cholesterol plays in the body and what health risks we become vulnerable to with low levels of cholesterol. I will also discuss the most recent scientific evidence on statins to enable anyone of you on a statin to be informed enough to approach your GP to discuss any concerns. Become educated and aware in order to improve your own health care How healthy is your heart? Is your blood pressure above 140/90? Is your resting pulse above 80? Is your cholesterol above 5.5?

- Gluten-Free: Fad or Problem?
Are you one of the many people who are confused about gluten? Is gluten really a problem for so many of us, or is gluten-free simply a fad? Fact: Humans have been consuming wheat in one form or another for thousands of years. Governments and dieticians tell us whole wheat is part of a 'balanced diet'. However: Renowned neurologist Dr Perlmutter, author of The Grain Brain Whole Life Plan, attributes the increase in neurological diseases to gluten and carbohydrates, labelling them 'your brain's silent killer'. A few key things to bear in mind about gluten: Wheat is not the same today as it was one-thousand, one-hundred, or even sixty years ago. Wheat, in particular gluten, exists today in an over-processed, hybridisation form; Whereas historically, grains were soaked, sprouted and fermented, and bread was baked using slow rise yeasts, today flour is bleached and bread is baked with quick rise yeast. Modern wheat involves cross-breeding and crude genetic manipulation, which has changed the nutrient and protein composition of the plant. Modern wheat contains more of the problematic glutens. Compared to older wheat varieties, modern wheat has adverse effects on blood mineral content, cholesterol and inflammatory markers, potentially contributing to disease. Common wheat-harvest protocol in the United States is to dredge wheat fields with Roundup several days before harvest. Roundup contains the deadly active ingredient Glyphosate, which has been implicated in numerous health issues. [1] Just because you have no gut-related symptoms, this does not necessarily mean that you do not have a problem with gluten. Fact: More and more studies are showing that even those who believe they do not have a problem with gluten are actually experiencing life-depleting side effects from eating it without realising. In fact, in a recent study, five out of six people who believed they had no gluten related symptoms had inflammatory autoimmune blood proteins when exposed to gliadin (gluten). [2] So: The biggest problem with gluten is the number of people who are unaware that it is a problem. Just because you have no gut-related symptoms, this does not necessarily mean that you do not have a problem with gluten. Did you know that the following symptoms are often due to gluten sensitivity? Anxiety Depression ADHD Muscle and joint aches Chronic fatigue Brain fog Autoimmune diseases Low immunity Migraines and headaches Skin problems Hormonal imbalances Adrenal fatigue It is common to blame these symptoms on something else rather than considering gluten could be the cause or contributor. TT's top tips on gluten If you are not feeling well for any reason, try cutting out gluten for a few weeks and see how you feel. Better still, get tested. Be aware that even when testing negative for celiac disease, many people still have a gluten intolerance. Gluten intolerance symptoms fall along a spectrum, with some people suffering more than others. Gluten sensitivity is not an 'all or nothing'. Beware the new gluten-free, highly processed, highly-refined products, spiking blood sugar and insulin levels. Look to buy gluten-free paleo breads such as Cru8 from Planet Organic, made from almonds, eggs, virgin coconut oil, pumpkin seeds, coconut flour and apple cider vinegar

- Prevention is Better than Cure: Stress Tips
Understanding the extent to which stress has a negative impact on one’s health is crucial. Stress is a manifestation of our ‘fight and flight’ response: a survival mechanism that has been pivotal to our evolution. In the 21st Century, we are experiencing more CHRONIC STRESS (a perpetual, daily feeling), as opposed to ACUTE STRESS (an incident occurs, we respond, the incident concludes, and balance is restored). The problem today is that most people are unaware that they are stressed. They remain in a perpetual state of constant agitation. Our bodies, however, are unable to distinguish between the non-life-threatening stressors of today (stuck in a traffic jam, 40 things on a to-do list etc.) and the life-threatening flight or flight stressors of thousands of years ago. The stress response is our survival instinct and is the same today as it was then. Survival takes precedence over ‘rest and digest,’ resulting in the shutdown of secondary bodily functions (such as digestion and immunity) when survival is at stake. May is going to be Stress/Relaxation month and we will be looking in greater depth at this essential part of your health and how to manage it. Stress is often unavoidable but it IS MANAGEABLE. If you change your response to stress this will have a positive impact on your resilience. This in turn will not only improve your health and strengthen your energy reserves but also remove one of the main obstacles to healing and wellness. FIND OUT in MAY why stress causes belly fat. TT’s Tips: • Simple breathing has a profound effect on the stress response. Learn more about breathing techniques which can be done anytime, anywhere; • Practise daily meditation. Even ten minutes a day can make a difference. Meditation apps such as Headspace, Calm and Buddify can help you get started; • Give yoga a try. Yoga is a mind-body practice, combining controlled breathing and meditation or relaxation that can help reduce stress.
- Prevention is Better than Cure: Food
Pick the statement that is true: A - Diet and Lifestyle impact your health. B - Your genetics predetermine whether or not you get ill, rendering you powerless. A. TRUE. The Human Genome Project has shown that diet and lifestyle can impact our health by as much as 90%[1] . We all have genetic mutations and weaknesses making us more vulnerable and predisposed to particular illnesses. The same underlying causes impact different people in different ways. However, we are not slaves to our genes. Genes merely load the gun. Diet and lifestyle pull the trigger. Every day this week, I will be highlighting one of the main five factors that are essential to your health, starting with the most important: FOOD. Food is a duel-edged sword. The right foods can heal you. The wrong foods can harm you. Foods that harm you – vegetable oils, most highly-processed foods, sugary drinks, most pizzas, white bread, most fruit juices (high in sugar), margarine, pastries, biscuits and cakes, chips and crisps, gluten-free junk food, processed cheese and meats, most fast food meals and anything that is high in sugar and refined grains. Foods that help to optimise your health: · Fruit and vegetables. Eating more fruit and vegetables is one of the simplest choices you can make to improve your health. This can help protect you from heart disease, stroke, arthritis, dementia, cancer and even slow down your body’s ageing process. Remember, ‘variety is the spice of life’. Build on the amount and variety of fruit and vegetables you include in your diet. · Healthy fats. Are you afraid of fats? If so, this is unsurprising as fat in foods has been vilified in the Western World for the past few decades. However the 'Big Fat Fraud' has finally been exposed and the 'low fat is good' health hypothesis has effectively been disproved. In fact, we are in the midst of an obesity epidemic that started around the 1980’s, coinciding with the rise of the low-fat hysteria. Type 2 diabetes has also risen significantly through this period. It is time for your body to reap the benefits of the healthy fats found in such foods as avocados, nuts and seeds, organic extra virgin olive oil, grass-fed organic butter and ghee, coconut oil and Omega-3s (found in seafood - like salmon and sardines - walnuts, chia seeds and flaxseeds). Here are TT's Tips for better eating: Avoid eating food that is high in toxins. Aim to buy organic where possible or wash non-organic in a bowl of water with a capful of apple cider vinegar to get rid of pesticides. Aim to buy organic meat and chicken to avoid antibiotics and growth hormones. If constrained by budget, it is better to buy less and to maximise by making stews and stir-fries and using bones for making healing bone broths. Eat real food. Aim to include a large salad in your diet every day. The more of these ingredients you include, the better: Dark leafy greens: Kale, Spinach, Swiss Chard, Arugula 1 cup broccoli sprouts Cauliflower Purple cabbage Slice of red onion, yellow or green onions Red, yellow or green peppers Mushrooms: White Button, Bella, Cremini, Shiitake Raw walnuts, almonds Raw sunflower, pumpkin seeds Sprouted beans like mung beans Sprouted black/green lentils. Consider other vegetables like radishes, artichokes, squash, and zucchini. Add avocado for healthy fats. Shake on as much of these anti-inflammatory, anti-cancer spices as you can stand (turmeric, curry powder, garlic powder, oregano) and remember herbs are nutrient-dense and add flavour. Coriander is also a powerful detoxing herb.
