I am responding to your article “Give us our daily meat” (You 24 July 2003) in which Richard van Rensburg reports on the so called miracle of high protein diets.

Firstly he does not name his sources and instead claims “suddenly researchers” and “researchers world wide”, “now respected researchers”, “foremost researchers” implying that everyone everywhere is in agreement. I can only assume that this “research” comes from a source that needs to promote animal protein for financial gain. He gives no independent research, quotes no real actual research or studies and quotes no studies published in recognised nutritional and medical journals.

So to counteract the nonsense in the article here is some real research from real researchers, not funded by an organisation or company that can gain from the information.

“Red meat, especially hamburgers, are associated with increase in non Hodgkin’s Lymphoma.”

“High intake of animal protein – more than 95 gm per day – showed a significantly higher risk of osteoporosis. Plant protein showed the least. (The average person following a Westernised diet, can easily consume 120 grams of protein daily)”

“The latest on protein levels – 45 gm daily for women and 55 gm daily for men. The average intake in the UK and USA is easily 80-90 gm daily.”

“A diet high in fat and meat increases cancer.”

“People consuming more meat, spend more money on medical expenses and cost the government more in medical costs.”
PREVENTATIVE MEDICINE, vol.24, November 95

“High intakes of meat and red meat were associated with a significant increase in breast cancer.”

“Increased intake of animal fat and animal protein shows a corresponding increase in breast cancer.”

Some More Facts
The Lancet ( Oct 1991) published research that clearly states that the only way to get rid of arthritis, is a vegetarian, plant-based diet.

Tests on rats, eating a 20% protein diet, all developed cancer, but those on a 5% protein diet were all clear. On a low-fat, high-protein diet, the rats developed hardening of the arteries and very high cholesterol levels, and after one year, 75% had developed kidney disease. (Health Revolution – Ross Horne)

“In the digestion of protein we are constantly exposed to large amounts of ammonia in our intestinal tract.”
Dr. Willard Visek, Clinical Sciences, University of Illinois Medical School

Ammonia behaves like a carcinogen, i.e. it kills cells, increases infections, affects the rate at which cells divide, and increases the mass of the lining of intestines. In the colon, statistics show that cancer parallels the concentration of ammonia. Ammonia is also formed when we badly combine foods.

“Compared to carbohydrates, the digestion of protein requires seven times the amount of water to flush out the ammonia produced.”
Dr. Nathan Smith, Prof. of Sports Medicine, University Washington

A high-protein diet makes extreme demands on the thyroid, resulting in the thyroid becoming sluggish.
“A potent carcinogen, Malonaldehyde (a chemical that begins to form in flesh soon after death), has been identified in beef and smaller amounts in pork, chicken, and fish.”
Dr. Raymond Shamberger of Cleveland Clinic Foundation

In 1968, when Danish researchers tested muscle energy levels of men cyclists, they found the following;
• Those eating a meat, milk, and egg diet, cycled for 57 minutes before muscle failure
• Those eating a meat and vegetable diet, cycled for 114 minutes before muscle failure
• Those on a vegetable, grain, and fruit diet, cycled for 167 minutes before muscle failure

Dr. Colin Campbell headed one of the most comprehensive nutritional research projects to date. The research involved Cornell, Oxford, and Beijing Universities, 6 500 Chinese people, and took nine years to complete. The conclusion? “Man is designed for a plant-based diet”, and if you wish to reduce your chances of developing any form of degenerative disease, you need to reduce your intake of animal protein and fat dramatically.


I suggest you try to reduce your animal-protein intake to not more than once a day, but eating meat one to three times a week is even better. Researchers clearly indicate that people on a plant-based diet have higher levels of health.

More Reasons to Avoid or reduce Animal Flesh

A chemically manufactured hormone that encourages rapid growth in all animals, it is fed to chickens, cows, pigs, and other livestock. It affects susceptible humans by causing premature maturation in children, breast cancer in women (One in ten women develop breast cancer in most Westernised countries, and an estimated 50% of these will die as a result of breast cancer), and in men it can result in sterility, breast formation, and effeminate behaviour.

This substance is fed to hens to make the yolks of their eggs as yellow as those of free range-eggs. It is suspected of being carcinogenic and causing an accumulation of crystals in the eyes, as well as damage to the liver in humans.

This is also fed to chickens so that their droppings are toxic to the fly larvae. It is absorbed into the bloodstream and remains in the flesh of the chicken. It is toxic to humans and as yet, no real long-term research has been done on the long-term effects of this substance to human beings.

This potent carcinogen begins to form in flesh soon after death.

High fat and or, high protein and low carbohydrate diet.
This is extremely dangerous, as this type of diet has been shown to encourage, if not cause heart disease, cancer, diabetes, arthritis and osteoporosis. A high protein diet will strain your kidneys and digestive tract contributing to disease in these areas.

It is physiologically a fact that the human body needs a high alkaline forming diet to maintain health. This will only work on an 80% raw fruit and veg diet. A high alkaline forming diet promotes a healthy Immune system and only in the right alkaline environment will fuel be converted into energy efficiently. A 75 – 80 % alkaline forming plant based diet will do this. If fuel cannot be converted into energy it will be stored and weight problems will result. (Dr Leonie van Heerden) If you follow the 5 Natural Way steps below, you will easily have an 80% alkaline forming diet.

The article further states that “No one has complained about these high protein diets yet over the years I have personally met many people who have developed serious health problems from these diets, such as constipation, haemorrhoids, heavy menstrual bleeding and menstrual disorders, depression, and increased blood sugar and blood pressure levels. I also have thousands of people who have seen a drastic reduction cholesterol levels when they reduce their animal protein intake.

Yes low fat diets are dangerous as fat is needed for all body functions, but in an unprocessed and unheated plant form. Incidentally animal fats are high in trans-fatty acids so your source is either misleading you or ignorant of real nutritional facts.

Yes you can lose weight on any diet including high protein diets, but your health will deteriorate, I have yet to find someone who does not develop some health problem somewhere down the line. Extracted from “Perfect Weight- The Natural Way” by Mary-Ann Shearer


“Despite their popularity, high-protein diets aren’t making good on their promise of long-term weight loss, says a new scientific advisory from the American Heart
Association. Moreover, the AHA says the diets are a health risk for people who stay on them beyond short periods of time. ‘In general, quick weight-loss diets don’t work for most people,’ says Robert H. Eckel, M.D., co-author of a scientific advisory from the AHA’S nutrition committee.

It’s important for the public to understand that no scientific evidence supports the claim’ that these diets work, Dr. Eckel says.

“In 1998 the AHA ‘declared war’ on fad diets for misleading claims of instant weight loss. But Tuesday’s advisory was the result of scientific documentation that
gives credibility to the AHA’s nutritional guidelines. The advisory specifically targets the Atkins, Zone, Protein Power, Sugar Busters and Stillman diets. Over the past decade these ‘quick weight loss’ regimens and their authors have topped best-seller book lists and have been promoted predominantly in the mass media.

“Some of the diets increase fat intake and reduce nutritionally rich foods such as fruits and vegetables, which is not a good approach to meeting a person’s long
term dietary needs,’ says Dr. Eckel, immediate past chair of the AHA’S nutrition committee. ‘Many of these diets fail to provide essential vitamins, minerals, fibre and other nutritional elements, in addition to their high fat content.’ Eating large amounts of high-fat animal foods over a sustained period has been shown to increase the risk of coronary heart disease, diabetes, stroke and several types of cancer, the advisory says.

“The statement notes that a diet rich in animal protein, saturated fat and cholesterol raises LDL (bad) cholesterol levels–an effect that is compounded when high-carbohydrate, high-fibre plant foods that help lower cholesterol are limited or eliminated. In the Atkins and Protein Power diets, the AHA is disturbed by the intake of saturated fat and cholesterol, as well as the risk for heart disease and stroke. Although the Zone, Sugar Busters and Stillman diets have lower fat, they are still high in protein, raising concern of kidney disease, particularly in people with kidney ailments and older adults with diabetes.

“Dr. Eckel says the public and health-care professionals should consider the possibility that these diets are associated with osteoporosis and cancer, although those
links have yet to be scientifically substantiated. [Because of] the lure of the fad [diets], more than half of all adults in the United States are either overweight or obese.

‘Many of these people are looking to high-protein diets as a popular ‘new’ strategy for successful weight loss,’ Eckel says.

“These diets cause a drop in weight primarily through loss of body fluids caused by the diuretic effect of eliminating most carbohydrates. Glycogen, the form of sugar used by the body for energy, is lost from the muscles as well, sometimes causing fatigue. Some of the diets also cause ketosis, a metabolic condition associated with low blood levels of insulin that results when the body is deprived of dietary carbohydrates.

“Sustained ketosis also causes a loss of appetite, which may lead to lower calorie intake. Matthew W. Gillman, M.D., associate professor of ambulatory care and prevention at Harvard Medical School and its Harvard Pilgrim Health Care affiliate, endorses the AHA advisory. ‘Because Americans often get lured by the fad and don’t see the dangers in going to extremes’, Dr. Gillman says, ‘ . . . we should be considering eating reduced amounts of the refined carbohydrates, but maybe not less carbohydrates overall.

Try, for example, eating whole grain breads, brown rice, and cereals that are high in fibre.’ But clearly, the quick fix promised by the high-protein diets is not the way to go, the AHA says. Studies consistently show that keeping weight off happens when people follow a nutritionally sound diet and increase physical activity to burn more calories than they consume.

“Experts recommend following current AHA guidelines on nutrition: a variety of foods, including fruits and complex carbohydrates such as breads, cereals, starchy vegetables,rice and pastas. . . . ”

These five natural way steps will help you find the right balance from a carbohydrate and alkaline forming approach. Start with at least one of them today as you keep reading and making small adjustments rather than one huge change.
1. Eat at least one fruit meal per day
2. All snacks should be fresh or dried fruit or vegetables
3. Try to eat no more than one animal protein meal a day
4. Start all cooked food with some raw vegetables
5. Try not to eat a concentrated protein with a concentrated starch at the same meal.

Incidentally, who ever your source is has neglected to inform you that Dr Atkins died a few months back (April 2003), supposedly from slipping on a pavement, (info from the billion dollar Atkins diet organisation, who are now sitting with millions of his diet books and no guru to promote them) . Exactly a year before in April 2002 Dr Atkins went into cardiac arrest and claimed it had “nothing to do with diet” but was just a condition he developed. Rumour has it that he died from a heart attack, but the Atkins Research Center has covered up the real cause of death.

“In 1999, Atkins established the Robert C. Atkins Foundation to finance diet research. It has sponsored research at Duke University, the University of Connecticut and Harvard.
Last April, Atkins was hospitalised for cardiac arrest, which he said was related to an infection of the heart and was not related to the diet.”
Possibly the info (research) you have is from Dr Atkins foundation, it certainly sounds like it, especially when you read the info below.
“In 1999. Atkins set up a foundation to provide “funding for research and education on the role of controlled carbohydrate nutritional protocols in treating and preventing a wide range of medical conditions.” [9] In 2002, a 6-month study funded by Atkins found that followers of the Atkins diet lost more weight than comparable people on a high-carbohydrate diet and improved their blood cholesterol and triglyceride levels [10]. However, the dropout rate was much higher in the low-carbohydrate group and the improved lipid levels did not necessarily mean that the diet would have a cardio protective effect in the long run [11]. In response to publicity about the study, the American Heart Association cautioned:
• A high intake of saturated fats over time raises great concern about increased cardiovascular risk. The study did not follow participants long enough to evaluate this.
• The study did not actually compare the Atkins diet with the current AHA dietary recommendations [12].
The Bottom Line
Although short-range studies have found that low-carbohydrate diets can produce weight loss, no study has demonstrated that such diets are safe or effective for long-term use [11-15]. Atkins advocated his diet for more than 30 years and stated that more than 60,000 patients treated at his centre have used his diet as their primary protocol. However, he never published any study in which people who used his program were monitored over a period of several years. Score-keeping can be done simply and inexpensively by mailing an annual questionnaire and tabulating the results. Why do you suppose he never did this?”
