High Protein Diet Has No Harmful Effects

Many people are under the impression that high protein diets are evil and cause all types of diseases, however a recent study says that notion is nonsense.

A study published in the Journal of Nutrition and Metabolism found that in resistance-trained men that consumed a high protein diet (~2.51–3.32 g/kg/d) for one year, there were no harmful effects on measures of blood lipids as well as liver and kidney function. In addition, despite the total increase in energy intake during the high protein phase, subjects did not experience an increase in fat mass.

Why We Need to Supplement

The word is out—it pays to take your vitamins.

In 2002, the American Medical Association (AMA) reversed its long-held anti-vitamin stance and began to encourage all adults to supplement daily with a multi-vitamin. A landmark review of 38 years of scientific evidence by Harvard researchers, Dr. Robert Fletcher and Dr. Kathleen Fairfield convinced the conservative Journal of the American Medical Association (JAMA) to rewrite its policy guidelines regarding the use of vitamin supplements. In two reports, published in the June 19, 2002 edition of JAMA, the authors concluded that the current US diet, while sufficient to prevent acute vitamin deficiency diseases, such as scurvy and pellagra, is inadequate to support long-term health.

Insufficient vitamin intake is apparently a cause of chronic diseases. Recent evidence has shown that suboptimal levels of vitamins (below standard), even well avocet those causing deficiency syndromes, are risk factors for chronic diseases such as cardiovascular disease, cancer and osteoporosis. A large portion of the general population is apparently at increased risk for this reason. — Dr. Fletcher and Dr. Fairfield

In the study, the authors examined several nutrients, including vitamins A, B6, B12, C, D, E, K, folic acid and several of the carotenoids (including alpha and beta carotene, cryptoxanthin, zeaxanthin, lycopene and lutein). Among their conclusions, they noted:

• folic acid, vitamin b6 and B12 are required for proper homocysteine metabolism, and low levels of these vitamins are associated with increased risk of heart disease (homocysteine is a sulphur-containing amino acid that, at high blood levels, can damage the cardiovascular system);
• inadequate folic acid status increases the risk of neural tube defects and some cancers (a neural tube defect is an incomplete closing of the spinal cord that occurs early in fetal development);
• vitamin E and lycopene (the red pigment found in ripe tomatoes) appears to decrease the risk of prostate cancer;
• vitamin D is associated with a decreased risk of osteoporosis and fracture when taken with calcium (osteoporosis is a hollowing out of the bones caused by the loss of calcium);
• inadequate vitamin B12 is associated with anaemia and neurological disorders (anaemia is a decrease in number of red blood cells or a lack of hemoglobin in the blood);
• low dietary levels of carotenoids, the brightly colored pigments in peppers, carrots and fruits, appear to increase the risk of breast, prostate and lung cancers (carotenoids belong to the family of nutrients called bioflavonoids);
• inadequate vitamin C is associated with increased cancer risk; and
• low levers of vitamin A are associated with vision disorders and impaired immune function

In a striking departure from JAMA’s long held anti-vitamin stance, the authors concluded that, given our modern diet, supplementation each day with a multi-vitamin is a prudent preventive measure against chronic disease. The researchers based their guidance on the fact that more than 80% of the American population does not consume anywhere near the five servings of fruits and vegetables required each day for optimal health.

JAMA’s previous comprehensive review of vitamins, conducted in the 1980’s, concluded that people of normal health do not need to take a multivitamin and can meet all their nutritional needs through diet alone. Since that time, nutritional science has compiled an impressive wealth of studies affirming the health benefits of supplementation as an adjunct to a healthy diet. The American Medical Association’s about-face in light of the Fairfield-Fletcher studies, and its public declaration that supplementation is now deemed important to your health, underscores the strength of the scientific evidence that now prevails.

The Case for Supplementation

We now have convincing evidence that the lifetime risk of cancer; heart disease; stroke; diabetes; neurological disorders, such as multiple sclerosis and amyotrophic lateral sclerosis (Lou Gehrig’s disease); macular degeneration; osteoporosis; Alzheimer’s disease and other forms of dementia can be reduced by providing the cells of the body with sufficient amount of the right nutrients.

One of the first human studies to substitute the benefits of vitamin supplements was announced in 1992 and showed that men who took 800 mg/day of vitamin C lived six years longer than those who consumed the US Food and Nutrition Board’s recommended daily allowance of 60 mg/day. Published in the journal Epidemiology, this ten year follow-up study showed that high vitamin C intake extended average lifespan and reduced mortality from both cardiovascular disease and cancer.

A compelling report that high-potency supplements extend human lifespan was published in August 1996, in the American Journal of Clinical Nutrition. The study involved 11,178 elderly people who participated in trial to establish the effects of vitamin supplements on mortality. Supplementation with vitamin E, alone, reduced the risk of overall mortality by 34% and reduced the risk of coronary disease mortality by 47%. However, when vitamin C and E were used together, overall mortality was reduced by 42% and coronary mortality dropped by 53%, demonstrating the synergistic effects of multiple vitamin therapy. What made these findings of even greater significance was that the study compared people who took low potency one-a-day multivitamins to those who took higher potency vitamin C and E supplements. Only those participants taking high-dose vitamin C and E supplements benefitted.

A 1997 study published by the British Medical Journal evaluated 1,605 healthy men with no evidence of pre-existing heart disease. Those men deficient in vitamin C were found to have a 350% increased incidence of sudden heart attacks compared to those who were not deficient in vitamin C. The authors concluded that vitamin C deficiency, as measure by low blood levels of ascorbate, is a significant risk factor for coronary heart disease.

A massive cohort study, published in 1998, investigated the risk for colon cancer in 88,756 nurses who took folic acid (a B-complex vitamin) as part of a daily multivitamin supplement.

The study found that intakes of 400 mg/day or more of folate, compared to intakes of 200 mg/day or less, were strongly related to lowered risk. While no significant protective effects were noted over shorter periods, an inverse relationship between folate intake and cancer risk became apparent after five years of use. After 15 years, a remarkable 75%reduction in the risk of colon cancer was noted among those women taking the supplements containing the B-complex vitamin. The authors concluded that longterm use of multivitamins might substantially reduce the risk for colon cancer, an effect likely related to the folic acid contained in these products.

In this same study, nurses who took multivitamins containing vitamin B6 also reduced their risk of heart attack by 30%. The evidence revealed that the more vitamin B6 they took, the lower the risk was of suffering a sudden cardiac event. These finding support those of another cohort study conducted in Norway that demonstrated a combination of folic acid and vitamin B6 can reduce homocysteine levels by up to 32% in healthy individuals. Homocysteine, a harmful amino acid at high blood levels, can markedly increase the level of inflammation and oxidative stress in blood vessels, which can precipitate both heart attack and stroke.

In 2005, an international coalition led by Canadian researchers at McMaster University, Ontario, provided evidence that a comprehensive ‘cocktail’ of nutritional supplements can significantly improve lifespan in animal models. The nutrient mixture, containing 31 nutrients common to many better quality broad-spectrum supplements available on the market, targeted key factors in the again process, including the proliferation of reactive oxygen species (ROS aka free radicals), inflammatory processes, insulin resistance and mitochondrial dysfunction. In the study, the treatment group of mice exhibited an 11% increase in lifespan compared to normal mice who did not receive the supplement cocktail. Previously, the same researcher established that the supplement cocktail completely abolished severe cognitive decline expressed by aging untreated mic. The results from these animal-model experiments demonstrate that broad-spectrum dietary supplements may be effective in ameliorating the effects of again and age-related pathologies where simpler formulation have generally failed.

The benefits of supplementation with n-3 polyunsaturated fatty acids (omega-3 fats) after a heart attack are well documented. Omega-3 fatty acids, commonly found in cold-water fish, nuts and grains, dramatically reduce the risk of premature death in high-risk individuals. A 2008 study on post-myocardial infarction (heart attack) patients revealed a significantly lowered likelihood of dangerous cardiac arrhythmia and an 85% reduction in the risk of premature death by simply maintain an optimal level of omega-3 fats in the diet. Moreover, these protective effects are also seen in healthy populations. In healthy people with no evidence of heart disease, men and women appear to achieve the same level of protection against premature death by supplementing with omega-3 oils from fish and nuts. In a 2010 Norwegian study, elderly men with no evidence of overt heart disease who supplemented with fish oil experience a 47% reduction in the risk of premature death compared to those who did not supplement. Similarly, a large Australian study found that women with the highest levels of omega-3 consumption from nuts and fish had a 44% reduction in the risk of premature death from inflammatory disease. The protective effect was dose-related to the level of omega-3 intake. The ability of omega-3 fats to reduce the level of systemic inflammation through the production of anti-inflammatory prostaglandins (primitive cell signaling hormones) appears to be the source of their protective talents. 

A 19-year study of colorectal cancer rates found the relative risk in men with poor vitamin D status was almost triple that of men with sufficient vitamin D. In a meta-analysis conducted on research worldwide from 1966 to 2004, researchers from the University of California concluded that 1,000 IU/day of vitamin D lowers an individual’s risk of developing colorectal cancer by as much as 50%. A 2006 review of vitamin D status and cancer risk in the northeastern United States concluded that efforts to improve vitamin D status through vitamin D supplementation could markedly reduce cancer incidence and mortality at low cost and with few or no adverse effects. A 2008 review of current research findings on the cancer-protective effects of vitamin D concluded that intakes of between 1000 and 4000 IU per day protect against cancers of the breast, colon, prostate, ovary, lungs and pancreas. Lastly, a 2009 review on ultraviolet radiation, vitamin D and cancer concluded that circulating levels of vitamin D play an important role in determining the outcomes of several cancers. According to the authors of this review, support for the sunlight/vitamin D/cancer link is scientifically strong enough to warrant the use of vitamin D in cancer prevention and treatment protocols.

These studies and their finding are but a few of the thousands of independent scientific reports confirming the efficacy of supplementation with high quality nutritional supplements as a prudent, preventative measure for optimal health and disease prevention.

The Other Side of the Coin

To be certain, the premise of life extension and disease prevention through supplementation does not have universal support amongst the scientific community. As is inevitably the case, in an evidence based discipline there will arise conflicting studies that cast doubt on the evidence. Many researchers argue that supplements provide a convenient and effective means for supplying the optimal intakes of essential nutrients required to support long-term health; others counter that there is no conclusive proof that supplements provide any real health benefits at all. 

Unfortunately, much of the debate is framed by a media more interested in selling newspapers than in ferreting out the truth. Sloppy reporting, distorted editorial sensationalism, and conflicts of interest by researchers and publishers have unnecessarily alarmed the public and have treated to destroy its trust in complementary health care. Health conscious consumers and medical practitioners alike have become frustrated at the mixed messages promulgated through the headlines: one day we are told something is good for us and the next day we are told it is bad for us. Why do so many recently published studies appear to refute the prevailing scientific evidence about the benefits of natural approaches to wellness? How can vitamin E be good for us one day and bad for us the next? For once, why can’t the experts just get it straight?

If it is of any consolation, it may be helpful to understand that science never progresses smoothly—there will always be new findings that appear to refute long established theories. Controversy is the crucible for change and paves the road that science must travel to arrive at a final truth. Unfortunately, media bias and conflicts of interest place unnecessary detours along the way.

Firstly, the consumer must understand that out of 100 clinical studies that investigate a particular effect, probability dictates that five of these studies—no matter how well designed—will show results that are not real. There will always be a statistical fluke in the bunch.

Secondly, about one-fifth of clinical trials investigating a particular effect will not have the needed number of subjects to show a statistically significant result. This occurs because in most clinical trials the probability of finding a real result, known as the power of a test, is set at a minimum of 80%. Consequently, there is up to a 20% chance of missing your mark and failing to find a different when one actually exists. This is merely the gremlin of probability at work.

Thirdly, some investigations are just bad science, improperly conducted, poorly reported and inadequately reviewed. Unfortunately, as has been the case in several recent studies, their findings attract an inordinate amount of attention from a media hungry for headlines.

Questions Concerning Soy Safety

While there are those out there who continue to praise soy as some kind of miracle food, evidence continues to emerge which exposes its many faults and raises questions about its safety. 

Soy and other foods and herbs with estrogen-mimicking properties are often recommended to menopausal and post-menopausal women because high consumption may lead to amelioration of some of the symptoms associated with the natural decline in estrogen levels. They are also sometimes included in protocols designed to reduce the effects of excess estrogen in women with “estrogen dominance” and elevated levels of the estrogen fractions associated with higher rates of breast cancer. Phytoestrogens bind to estrogen receptors in the human body, thereby blocking the binding of the body’s natural estrogen. And since these plant estrogens have a much milder effect than true estrogen, they are believed to help with some of the symptoms associated with excess estrogen. Soy seems to play both sides of the coin: it has estrogenic effects, but can also be used to lessen estrogenic effects. Head spinning yet? Perhaps this is why the results of studies looking at soy and female health are so mixed.

Soy is also touted as a good source of protein, because it is one of the only complete proteins among plant foods (meaning it contains all the essential amino acids; although like all legumes, it is low in methionine). However, what is often not mentioned in the same sentence when soy is being touted as a plant-based protein source is that soy is also notorious for interfering with digestion of the very protein it provides. Soy contains trypsin inhibitors—compounds that reduce the efficacy of digestive enzymes—and these hardy anti-nutrientswithstand a high level of processing, so they’re still present in most commercial soy foods.

While Asian diets—commonly cited for being more health-promoting than Western diets—do contain soy products, they are usually prepared by traditional fermentation methods that reduce the potency of the digestive inhibitors and anti-nutrients. Moreover, soy sauce, miso, natto, and edamame are consumed in small quantities, and sometimes only as a garnish. Soy consumption in Asia is a world apart—no pun intended—from soy consumption in the modern United States, where vegetarians and vegans following plant-based diets can sometimes be better referred to as “soytarians.” They consume unprecedented amounts of soy, largely in the form of highly refined, puffed, extruded, and otherwise processed foods, such as soy milk, soy-based breakfast cereal, soy “chicken,” soy “cheese,” textured vegetable protein, and other soy-based foods marketed as imitation meat and dairy products.

Adults who have made a deliberate decision to consume a lot of soy aren’t the only ones affected by soy’s potentially adverse effects. With 25% of infant formula in the U.S. being soy-based, developing babies can be unwitting participants in an experiment that may have negative consequences for their long-term health. 

A recent study sheds light on a possible connection between increased seizure rates in autistic children fed soy formula, as compared to those fed dairy formulas. The author also found an association between soy formula consumption and epilepsy. The study identified a comorbidity of autism and epilepsy of 1.6–3.8%, which is higher than in the general population. Within that, among soy-fed infants there was a 3.6% rate of epilepsy, which is over twice as high as the 1.7% among non-soy fed infants. These numbers might seem very small, but as the author points out, “These may be considered by some readers as small percentages in each group who had seizures, but the two-fold or greater differences between soy and non-soy diets are statistically significant. Pharmaceutical interventions that reduced the incidence of febrile seizures or epilepsy by 2-fold would be in demand.” 

It’s important to note that these were associations, and they do not necessarily imply causality. However, similar findings relate soy consumption to seizures in other populations, as shown in an animal model of neurological diseases. Nevertheless, although the study was small and retrospective, it raises concerns which, when combined with other studies that sound the alarm, suggest people should be more cautious when ingesting large amounts of soy products that may have adverse effects on the body’s endocrine and neurological functions—particularly in populations as vulnerable as developing infants.

Calcium Supplements May Damage the Heart

After analyzing 10 years of medical tests on more than 2,700 people in a federally funded heart disease study, researchers at Johns Hopkins Medicine and elsewhere conclude that taking calcium in the form of supplements may raise the risk of plaque buildup in arteries and heart damage, although a diet high in calcium-rich foods appears be protective.

In a report on the research, published Oct. 10 in the Journal of the American Heart Association, the researchers caution that their work only documents an association between calcium supplements and atherosclerosis, and does not prove cause and effect.

But they say the results add to growing scientific concerns about the potential harms of supplements, and they urge a consultation with a knowledgeable physician before using calcium supplements. An estimated 43 percent of American adult men and women take a supplement that includes calcium, according the National Institutes of Health.

“When it comes to using vitamin and mineral supplements, particularly calcium supplements being taken for bone health, many Americans think that more is always better,” says Erin Michos, M.D., M.H.S., associate director of preventive cardiology and associate professor of medicine at the Ciccarone Center for the Prevention of Heart Disease at the Johns Hopkins University School of Medicine. “But our study adds to the body of evidence that excess calcium in the form of supplements may harm the heart and vascular system.”

The researchers were motivated to look at the effects of calcium on the heart and vascular system because studies already showed that “ingested calcium supplements — particularly in older people — don’t make it to the skeleton or get completely excreted in the urine, so they must be accumulating in the body’s soft tissues,” says nutritionist John Anderson, Ph.D., professor emeritus of nutrition at the University of North Carolina at Chapel Hill’s Gillings School of Global Public Health and a co-author of the report. Scientists also knew that as a person ages, calcium-based plaque builds up in the body’s main blood vessel, the aorta and other arteries, impeding blood flow and increasing the risk of heart attack.

Getting the Most Out of Your Workout

Pre-workout supplements have never been more popular. They provide you with increased energy and endurance for your workout; however, there are several issues to consider when choosing the best approach for yourself or your patients.

One of the most important things to consider when evaluating your options is that many popular pre-workout supplements are loaded with stimulants. There is nothing wrong with a little caffeine, but most of the pre-workout products on the market contain as much caffeine as five cups of coffee. In addition, many also contain food dyes and artificial sweeteners, with most powders being sweetened with sucralose. While food manufacturing companies and global health authorities have deemed sucralose safe for consumption, most health care providers know that this is not the case. According to a recent study in theJournal of Toxicology and Environmental Health, sucralose is a biologically active compound that decreases the number and balance of beneficial bacteria in the gastrointestinal tract; causes epithelial scarring, the depletion of goblet cells and glandular disorganization in the colon; and alters insulin, blood glucose, and glucagon-like peptide 1 (GLP-1) levels.1 

I started weight training 16 years ago and have been a competitive powerlifter for the past four years. I know the importance of nutrients for supporting focus, energy, and endurance. The challenge is finding good, health-promoting products that do not have excessive amounts of caffeine, while also being free of artificial sweeteners and food dyes.

These are some nutrients that I have personally found to be effective and safe to take prior to training: 

Creatine has been heavily researched for the past 20 years and is ideal for people who are sensitive to stimulants. Creatine supplementation can increase tissue concentrations of this nutrient to a level that is unobtainable through the diet alone. However, it is important to use a creatine supplement in a stabilized, alkaline form so it does not raise creatinine (a metabolite of creatine). Many of the side effects of taking high-dose creatine supplementation are not from the creatine itself, but are actually from creatinine.

Acetyl L-carnitine is one of the most extensively researched brain nutrients with a proven ability to enhance mental energy. Most people associate acetyl L-carnitine with preventing age-related memory decline and slowing Alzheimer's; however, it is also very effective when used pre-workout for increasing mental focus and energy.

Glycerophosphocholine (GPC) is an activated form of choline that crosses the blood brain barrier. GPC is another brain nutrient commonly used for age-related brain conditions and brain recovery from stroke or trauma. GPC also has other benefits, such as enhancing growth hormone secretion. According to a study in Nutrition, plasma growth hormone secretion was increased significantly 60 minutes after taking GPC, whereas no significant change was observed with the placebo.2

L-Arginine is a non-essential amino acid that is important for many cellular functions. It is a precursor to nitric oxide, which increases blood flow, thereby raising the supply of oxygen and nutrients to muscles.

Medium chain triglycerides (MCTs) provide a great energy source for weight lifters. MCTs are quickly converted into energy, sparing amino acids from being used as fuel. This is essential for athletes restricting their carbohydrate intake, intermittent fasting, carb back-loading, or following the "warrior diet.”

Caffeine is definitely beneficial but not a lot is needed to get the job done. It also depends on the time of day that you are training. I prefer to mix coconut oil in tea (coffee may be preferable to many, but I myself do not drink coffee) prior to training. A good alternative is to use an MCT oil supplement containing coconut and palm oils.

Choosing the right supplements can have a large impact on what you are able to get out of your workouts, but sifting through the stimulants, dyes and unhealthy sweeteners can be discouraging. This list presents safe and beneficial nutrients that support athletic performance, as well as some brain nutrients that are often not thought of when formulating a pre-workout regimen, yet can be extremely helpful for focus and mental energy in athletes.  I can honestly say that I feel and see the difference in my workouts now.

Fat is Good. Animal Fat is Best.

The most important fats which should be consumed daily and which should constitute the bulk of all fat consumption, are animal fats: fats in fresh meats, fats rendered from meats, dairy fats (butter, cream and ghee) and fats in egg yolks. Animal fats contain largely saturated and monounsaturated fatty acids.

I’m sure you’re begging to ask the questions: What about the “deadly” saturated fats? Don’t they cause heart disease? Aren’t animal fats all saturated? Well, this is the result of the relentless efforts made by the food industry to fight their competition. What is their competition? The natural fats, of course. There is not much profit to be made from the natural fats, while processed oils and fats bring very good profits. So, it is in the food industry’s interest to convince everybody that natural fats are harmful for health, while their processed fats, hydrogenated and cooking oils are good for us. We have been subjected to this propaganda for almost a century, so it is little wonder that many of us have succumbed to it.

The saturated fats in particular were singled out by the food industry. How did this happen? Dr. Mary Enig, an international expert to lipid biochemistry, explains: “In the late 1950s, an American researcher, Ancel Keys, announced that the heart disease epidemic was being caused by the hydrogenated vegetable fats; previously this same person had introduced the idea that saturated fat was the culprit. The edible oil industry quickly responded to this perceived threat to their products by mounting a public relations campaign to promote the belief that it was only the saturated fatty acid component in the hydrogenated oils that was causing the problem … From that time on, the edible fats and oils industry promoted the twin idea that saturates (namely animal and dairy fats) were troublesome, and polyunsaturates (mainly corn oil and later soybean oil) were health-giving.”

The wealthy food giants spend billions on employing an army of “scientists” to provide them with “scientific proof” of their claims. In the meantime the real science was, and is, providing us with the truth. However, it is the food giants who have the money to advertise their “science” in all the popular media. Real science is too poor to spend money on that. As a result, the population only hears what the commercial powers want them to hear.

So let us dive into the truth that real science has provided us:

1. Processed fats, hydrogenated fats and cooking vegetable oils cause atherosclerosis, heart disease and cancer. This is a fact, proven overwhelmingly by real science.

2. Animal fasts have nothing to do with heart disease, atherosclerosis and cancer. Our human physiology needs these fats; they are important for us to eat on a daily basis.

3. Saturated fats are heart protective: they lower the Lp(a) in the blood (Lp(a) is a very harmful substance which initiates atherosclerosis in the blood vessels), reduce calcium deposition in the arteries and are the preferred source of energy for the heart muscle. Saturated fats enhance our immune system, protect us from infection and are essential for the body to be able to utilize the unsaturated omega-3 and omega-6 fatty acids. One of the most saturated fats that Nature has provided is coconut oil. It has been shown to be wonderfully healthy and therapeutic in most degenerative conditions.

4. Animal fats contain a variety of different acids, not just saturated ones. Pork fat is 45% monounsaturated, 11% polyunsaturated and 44% saturated. Lamb fat is 38% monounsaturated, 2% polyunsaturated and 58% saturated. Beef fat is 47% monounsaturated, 4% polyunsaturated and 49% saturated. Butter is 30% monounsaturated, 4% polyunsaturated and 52% saturated. This is the natural composition of animal fats and our bodies use every bit. Including the saturated part. If you want to understand how important every bit of the animal fat is for us let us have a look at the composition of human breast milk. The fat portion of the breast milk is 33% monounsaturated, 16% polyunsaturated and 48% saturated. Our babies thrive beautifully on this composition of fats and the largest part of it is saturated.

5. We need all the natural fats in natural foods, and saturated and monounsaturated fats need to be the largest part of our fat intake.

6. The simplistic idea that eating fat makes you fat is completely wrong. Consuming processed carbohydrates causes obesity. Dietary fats got into the structure of your body: your brain, bones, muscles, immune system, etc. -- every cell in the body is made out of fats to a large degree.

These are the facts which real science has provided. Unfortunately, as already mentioned, most of us do not hear about the discoveries of real science. Spreading any information in this world costs money. So, the population at large mostly gets information that serves somebody with a fat wallet. In order to get the real, true information on any subject, we have to search for it, rather than relying on news reports of “scientific breakthroughs” unleashed on us by the popular media.

Directing our attention back to the fat composition of human breast milk again we remember it is 33% monounsaturated, 16% polyunsaturated and 48% saturated. Mother Nature does not do anything without good reason. Human breast milk is the best and the only suitable food for a human baby. Human physiology does not change as babies grow, so our requirements for a particular fat composition in food stay about the same throughout our lives: 33% monounsaturated, 16% polyunsaturated and 48% saturated. This is what we need as it is what Mother Nature intended. The only foods with this composition of fats are animal products: meats, eggs and dairy; and these are the foods that should provide us with the bulk of all fats we consume.

Fats which plants contain have a very different fatty acid composition, they are largely polyunsaturated. Polyunsaturated fatty acids are very fragile, they are easily damaged by heat, light and oxygen. That is why Mother Nature has locked them up and protected them very well in the complex cellular structure of seeds and nuts. When we eat seeds and nuts in their whole natural state we get the fatty acids in their natural state, unchanged and beneficial to health. When we extract oils from seeds and nuts in our big factories, we damage fragile polyunsaturated fatty acids and make them harmful to health. But the most important point is this: when we consume whole natural seeds and nuts, we get their polyunsaturated oils in small amounts, amounts which are compatible with our human physiology. We do not need a lot of polyunsaturated fats, the bulk of our fat consumption should be saturated and monounsaturated fatty acids. When we consume vegetable and cooking oils, we consume their polyunsaturated fatty acids in excess, far too much for healthy human physiology. It is excessive omega-6 polyunsaturated fatty acids from vegetable and cooking oils that are to a large degree causing an epidemic of inflammatory degenerative conditions in our modern world, from heart disease and various autoimmune problems to cancer.
