The Taboo Against Animal Fat

(The first of two posts about the damaging effect of the western diet on intestinal bacteria and human health.)

As a traditionally trained physician, I watch with horror and dismay as for-profit corporations intrude ever deeper into so-called evidence based medicine. I have written at length about the role of Big Pharma in corrupting good medical practice to promote the sale of prescription pharmaceuticals – and their bottom line (see Menopause: Made in the USA and Drug Companies: Killing Kids for Profit). The role of Food Inc in the dietary recommendations doctors (and government) make to patients and the public at large are even more insidious and damaging.

The current taboo against saturated animal fats is a case in point. For the past thirty years, doctors and government agencies have been lecturing us that diets high in saturated animal fats (found in red meat, whole milk, eggs, butter and lard) cause high cholesterol levels, heart disease and stroke. They have persisted in this three decade campaign against animal fat – despite the total absence of scientific research supporting a link between fat intake and high cholesterol levels – or heart disease and and stroke. In fact, growing evidence suggests just the opposite: diets low in saturated fats and high in sugar and refined carbohydrate promote obesity, type 2 diabetes, high cholesterol levels, high blood pressure, heart disease and stroke.

In other words, government and the medical fraternity have it backwards. Worse still, it appears that their purely theoretical (based on no evidence) phobia against animal fat may be the single most important factor in the current epidemic of obesity and type 2 diabetes.

An Unproven Hypothesis

The current taboo against animal fats is based on a hypothesis first promoted forty years ago when I was in medical school. The theory works like this:  consumption of foods high in cholesterol and saturated fats promotes high levels of blood cholesterol, which lead to calcified plaque formation in arteries, which restrict blood flow to the heart and brain, as well as increasing blood pressure by making blood vessels less elastic.

There’s a credible body of research linking high cholesterol levels to plaque formation and the latter to high blood pressure, heart attack and stroke. However there’s no research whatsoever linking diets high in animal fats and cholesterol to high blood cholesterol levels.

In March, Annals of Internal Medicine published a metanalysis of 72 scientific studies on the effect of different fats on heart disease. The authors conclude there is insufficient research evidence to support guidelines discouraging consumption of saturated animal fats.

The Work of Weston A Price

A growing body of evidence suggests that diets low in saturated fats are, in fact, harmful to human health. Many of these studies were inspired by the work of dentist Weston A. Price in the 1930s. Puzzled that Maori, Australian aboriginals and other indigenous groups experienced no tooth decay prior to adopting a western diet, Price studied their dietary habits. To his surprise, he discovered it wasn’t the direct effect of sugar on tooth enamel that caused cavities. His patients developed tooth decay because diets high in sugar and refined carbohydrates were deficient in basic nutrients essential for human health. When he helped them alter their diets, his patients not only avoided further tooth decay but healed existing cavities.

One of Price’s discoveries was that animal fats* provide essential fat-soluble vitamins (A, D, E and K) that play a vital role in the absorption of other nutrients essential for hormonal and neurological function and protection against chronic diseases, such as cancer and heart disease.

The Role of Intestinal Bacteria

More recent studies have elucidated the mechanism by which diets high in sugar and refined carbohydrate predispose to both high cholesterol levels and obesity. Some of this research is summarized in an April 2013 article in Mother Jones Are Happy But Bacteria Key to Weight Loss?

The article explains how high sugar and refined carbohydrate diets, coupled with massive antibiotic overuse in medicine and factory farming**, promote the growth of gram negative, endotoxin-producing intestinal bacteria. When endotoxin is absorbed into the bloodstream, it sets up a wide ranging inflammatory response that can manifest a variety of effects, including arthritis, eczema, psoriasis and neuropsychological syndromes such as autism, Asperger’s disorder, schizophrenia and ADHD. A number of studies suggest that high cholesterol levels are also an inflammatory response to this endotoxin. Others link endotoxin to inflammatory damage in the brain’s appetite center. An impaired appetite center will cause people and animals to eat indefinitely without ever feeling full.

The Mother Jones article also describes several studies in which obese patients lost weight by simply suppressing endotoxin-producing bacteria – by taking probiotics and eating fermented foods containing beneficial bacteria.

*The contamination of animal fats and dairy products, even when produced organically, with fat-soluble pesticides and other industrial toxins makes choosing “safe” saturated fats somewhat problematic. Classified as endocrine disruptors, many of these toxins mimic estrogen, which promotes the development and growth of breast cancer. For this reason, I prefer coconut oil as my saturated fat of choice.

**Factory farmed animals are routinely fed antibiotics to hasten and maximize growth.

Ending Water Fluoridation: One We Can Win*

The Fluoride Deception

By Christopher Bryson (2004 Seven Stories Press)

Book Review

In Fluoride Deception, BBC journalist Christopher Bryson describes how the decision to deliberately dose US municipal water supplies with a potent industrial toxin was basically a corporate scam dreamed up by Alcoa, GM and Dupont, with the help of Edward Bernays, the infamous father of the public relations industry. Their cynical goal was to stem a tide of lawsuits related to death and injuries from toxic fluoride pollution – by convincing the public that fluoride is good for you.

Fluoride is an extremely toxic pollutant produced by aluminum smelting. GM and Dupont became involved with the scheme because GM held the patent on fluoride-based Freon and Dupon manufactured it. Freon was a common refrigerant which the EPA banned in 2010.

According to Bryson, the FDA first raised the alarm about fluoride toxicity in the early thirties, resulting in scores of lawsuits for aluminum workers crippled and killed from fluoride poisoning and farmers near aluminum plants, whose livestock were killed due to fluoride poisoning.

Public Relations: Cheaper than Pollution Controls

Rather than encouraging Alcoa to institute pollution controls, an Alcoa researcher named Francis Frary decided a better approach was to alter public perception of fluoride. He approached Mellon Institute researcher Gerald Cox. In 1937, Cox performed a single study in rats (who rarely suffer tooth decay to begin with) in 1937 and “proved” fluoride strengthened their teeth.

Frary and Cox were soon joined in their little scheme by Charles Kettering’s GM’s research director and Freon magnate, who approached the American Dental Association, began funding many of their activities. He also got himself appointed to their three member Advisory Committee on Research in Dental Caries. Meanwhile GM and Dupont hired scientist Robert Kehoe to perform safety studies on both fluoride and tetra ethyl lead, a gasoline additive co-manufactured by the two companies. Unsurprisingly, Kehoe declared both leaded gasoline and fluoride safe at “low levels.”

Enter the Father of Public Relations

The most prominent villain in this sordid history was Edwards Bernays, the father of public relations industry. At the beginning, there was massive public opposition to water fluoridation, led mainly by doctors who were well aware of fluoride’s toxicity. Bernays’ answer was to enlist even more prominent doctors to declare it safe, starting with prominent baby doctor Benjamin Spock.

The common perception of a potent toxin such as fluoride being safe and good for teeth is based on decades of corporations paying researchers to produce the scientific results they want – and burying research and firing and blacklisting scientists whose studies show otherwise.

Bryson details numerous deliberate smear campaigns against extremely reputable doctors and scientists who dared to publish research regarding the adverse effects of water fluoridation:

• Dr. George Waldbott a world famous doctor who first identified penicillin allergy and the link between smoking and emphysema. Waldbott published numerous double blind studies in the fifties showing that fluoride is harmful to human health. The result was a massive corporate smear campaign that destroyed his reputation by marginalizing and demonizing him.
• Dr William Marcus – a senior EPA toxicologist in the Office of Water, fired in 1992 for attempting to publicize studies showing that  fluoride causes bone and liver cancer. In 1994 Marcus won lawsuit against the federal government and was reinstated. While the EPA still refuses to ban water fluoridation, the unions representing EPA scientists have called for a moratorium.
• Dr Phyllis Mullinix – research toxicologist hired by Forsyth Dental Institute to study the effect of fluoride on the brain. Mullinex was first fired and then blacklisted in the mid-nineties when she published research showing fluoride produces memory and behavior problems in children.

Where Fluoride Comes From

Although fluoride is added to municipal water supplies as a “drug” – that allegedly improves dental health – it has never been approved by the FDA. In fact most communities source their fluoride from the phosphate fertilizer industry, as hydrofluorosilicic acid. This is an extremely toxic, hazardous waste, and the EPA requires phosphate manufacturers to capture it via “wet scrubbers” in their chimneys (to prevent toxic fluoride gas from being released into the air). The resulting liquid is then loaded, unpurified, into tanker trucks and sold to cities to be added to their public water supply. In addition to fluoride, it also contains a number of heavy metals and radionucleotides (radioactive elements – mainly uranium-238, uranium-234, thorium-230, radium-226, radon-222, lead-210, and polonium-210).

*2014 update

In 2003 the EPA commissioned the National Research Council (part of the National Academy of Sciences) to examine all the peer reviewed research to make a determination whether an upper limit of 8 mg of fluoride (eight glasses of water with a fluoride concentration of 4 mg/liter) was still within the margin of safety. In 2006 the NRC came back with the recommendation that 8 mg (4 mg/liter) was definitely too high – as many Americans were experiencing symptoms of chronic fluoride poisoning at this dose.

In addition to lower IQ in children, the NRC found that water flouridation was contributing to an epidemic of hypothyroidism, infertility, arthritis and hip fracture.

Based on the high probability that Americans drinking fluoridated water were suffering serious and irreversible health damage, the NRC urgently recommended that the EPA ban water fluoridation until the safe threshold (based on urine fluoride measurements) could be determined.

The Bush administration and corporate media buried the report.

98% of European municipalities have banned water fluoridation.

In 2011, I was part of a local citizen’s groups that persuaded New Plymouth District Council to remove the fluoride from our water. We had major support from New Zealand’s Fluoride Action Network and internationally renowned biochemist Dr Paul Connett.
