The Cholesterol Myths: Exposing the Fallacy that Saturated Fat and Cholesterol Cause Heart Disease

With courage and care Dr. Ravnskov exposes the lack of experimental evidence for the diet-heart theory, which claims that eating less fat and cholesterol will prevent atheroslcerosis (hardening of the arteries) and myocardial infarctions (heart attacks). By examining original peer-reviewed literature, the author finds no support for the diet-heart theory. He gives examples of scientific fraud among efforts to support the theory, including the deliberate selective omission of data points, and the deliberate assignment of subjects in a clinical trial to treatment or to control groups by physicians with the subject's medical records in hand. He shows how the abstract or conclusions of a number of papers are at odds with the actual data in the papers. He demonstrates how the use of one statistical method in preference to another can give a false impression that there is an effect, where there is, in fact, none. He shows how the reporting of differences in fatality rates by per cent reduction (say, a 50% reduction in relative risk) is actually misleading when the actual death rates are quite small in both the treatment and control groups of subjects in diet or drug studies. For example, a treatment that changes the absolute survival rate over a multi-year period from 99.0% to 99.5% represents a 50% reduction in relative risk, from 1% to 0.5% absolute. This is often described in papers as a 50% reduction in death rate. However, when the difference is barely significant statistically, as was often the case, Ravnskov points out that there is no real reason to recommend adoption of the treatment, especially if there are serious side-effects.

I have provided an abnormal number of quotations in order to show how meticulous this author is, and how skeptically we should regard some of the peer-reviewed literature, or recommendations from the medical establishment, or claims of effectiveness of anti-cholesterol drugs. Surprisingly, this author has included about 2 dozen cartoons to make this very wrenching exposé more palatable. The chapters are called Myths. Here are the chapter titles along with some quotations from and discussion of each:

"Myth 1: High-fat foods cause heart disease." In a striking graph from one of the papers of John Yudkin, M. D., Dr. Ravnskov shows that the number of deaths from coronary heart disease (CHD) in England and Wales between 1910 and 1956 is closely correlated with the number of new radio and television sets purchased each year. This is a perfect example of a correlation without a cause. Another line on the same graph shows that the number of grams of animal fat consumed per day changed by only ± 10% during this period. There is no correlation whatever between fat consumption and death rates from CHD, which increased 6-fold during this time period. "In the US, coronary mortality increased about ten times between 1930 and 1960, leveled off during the '60s and has since decreased slowly. During the decline of heart mortality the consumption of animal fat declined also, but during the thirty years of sharply rising coronary mortality the consumption of animal fat decreased [also]."

"While the death rate from coronary disease increased in most countries after World War II, it decreased in Switzerland. If this decrease had been preceded by a decline in the intake of animal fat, Switzerland would have been a model for health care in other countries. But the diet-heart proponents never mention Switzerland because during the decline in heart mortality, the Swiss intake of animal fat increased by 20%."

"The Masai [of Kenya] drink 'only' half a gallon of [whole] milk each day...Their parties are sheer orgies of meat; on such occasions four to ten pounds of meat [eaten] per person is not unusual, according to Professor [George] Mann [of Vanderbilt University in Nashville, TN, USA]. If the diet-heart idea were correct, coronary heart disease would be epidemic in Kenya. But Professor Mann found that the Masai do not die from heart disease - although they might die from laughter if they heard about the campaign against foods containing cholesterol and saturated fat. But this was not the only surprise. The cholesterol of the Masai tribesmen was not sky-high as Mann had expected; it was the lowest ever measured in the world, about 50% lower than the value of most Americans."

"In Puerto Rico and in Honolulu, heart attack victims had consumed more polyunsaturated oils than those who had not had a heart attack [in a study conducted by Dr. Tavia Gordon]. Although this observation is contrary to what was expected and thus most discouraging for those who advise people to consume more vegetable oils, the study authors did not mention this fact in the summary of their research."

"By 1998, a total of 27 studies had been published including 34 groups (cohorts) of patients and control individuals...[totaling more than 150,000]. In 3 of these 34 cohorts, patients with coronary disease had eaten more animal fat than the control individuals, and in 1 cohort they had eaten less. In the rest of the groups - 30 in all - investigators found no difference in animal fat consumption between those who had heart disease and those who did not. In 3 cohorts the patients had eaten more polyunsaturated vegetable oils than the control individuals, and in only 1 had they eaten less..."

"If you go to the library and look into the tables of these papers [all are fully cited in the book] you will see that the differences found were not statistically significant, which means that the results were simply due to chance."

"...[T]here is a weak association between the coronary mortality in various countries and the amount of fat available [in each] for [the citizens] to eat, but no difference between the amount of fat [actually] eaten by coronary patients and by healthy individuals."

"Myth 2: High cholesterol causes heart disease." "Most supporters of the diet-heart idea think that the increased risk of CHD is present at all cholesterol levels. Those who have a cholesterol level of 200 mg/dL, for example, are worse off than those with a cholesterol level of 150 mg/dL; and those who have a cholesterol level of 250 mg/dL are at even greater risk. The pharmaceutical companies love this concept for it implies that almost everyone should be treated, even those with normal cholesterol levels."

"The truth, were it known, would send pharmaceutical stocks plunging. In most studies, the increased risk is present only above a level of cholesterol that includes just a small percentage of the total population. [These are the approximately 1% of people with a genetic defect called familial hypercholesteremia.] And women can stop worrying immediately because high cholesterol is not a risk factor for the female sex. Few comments have been made on this peculiar fact in all the vast literature on cholesterol. When it is mentioned at all, it is said that female sex hormones protect against heart attacks."

"In fact, it seems more dangerous for women to have low cholesterol than high. Dr. Bernard Forette and a team of French researchers from Paris found that old women with very high cholesterol live the longest. The death rate was more than 5 times higher for women who had very low cholesterol. In their report, the French doctors warned against cholesterol lowering in elderly women. But they could as well have warned against cholesterol lowering in any woman, or, to be more precise, in anyone at all."

Dr. Ravnskov showed how the results of many studies, including those of Dr. Ancel Keys, as well as MRFIT and others, have conclusions that are at odds with the authors' own data, albeit sometimes this problem was confined to the abstract of a paper, as though no further funding would be obtained if honest and complete interpretations had been made.

Your reviewer checked one of the citations on MRFIT [O. Paul et al., J. Amer. Medical Assoc. 248 (12), 1465-1477 (1982)], to find that the summary noted honestly that the treatment group had less mortality from CHD and more overall than the controls did. That the former was not statistically significant was in the abstract; that the latter was not statistically significant was not in the abstract, but in the body of the paper. The problem with both this and some other studies is that the interventions included diet, anti-hypertensive drugs and smoking cessation all at once. The authors thought that less smoking was beneficial and that anti-hypertensive drug therapy was harmful. But the diet for the treatment group called for lower saturated fat and cholesterol intake and higher polyunsaturated fat intake. The authors did not admit the possibility that this intervention could have been harmful. In an end-note Ravnskov simplified a table in this paper and showed that the entire difference in death rates of sub-groups was due to quitting smoking, which cut the death rate in half for those who quit.

"Thus, high cholesterol is said to be dangerous for Americans but not for Canadians, Stockholmers, Russians or Maoris. High cholesterol is said to be dangerous for men, but not for women; it is said to be dangerous for healthy men, but not for coronary patients; and it is said to be dangerous for men of 30, but not for those of 48 [or older]. And high cholesterol may even be beneficial for older people. Such discrepancies indicate that the association between high cholesterol and CHD is not due to simple cause and effect. The most likely interpretation is that high cholesterol is not dangerous in itself but [that it is] a marker for something else."

Dr. Ravnskov went on to show that higher levels of high-density-lipoprotein (HDL, "good" cholesterol) are not protective against CHD, and that lower levels of low-density-lipoprotein (LDL, "bad" cholesterol) are not beneficial, although the expected associations of each with CHD are present. Here again, conclusions at odds with the researchers' own data were presented. Intimations that there are "many" or "definitive" studies in reports and papers were shown to be false by showing that citations often led to other reviews, each trusting the last, and ending at very few original studies.

Studies in test animals that artificially raised their LDL-cholesterol levels, thereby supposedly creating atherosclerosis, were shown to be misinterpretations. While the topic should have been in Myth 1, not in Myth 2, triglycerides were said to be even less correlated with CHD than cholesterol is; that the assay for triglycerides is worthless unless the patient has been fasting 12 hours; and that the assay is only accurate to ± 50%.

"Myth 3: High-fat foods raise blood cholesterol." Dr. Ancel Keys was one of the main proponents of this myth. In a paper published in 1958, Keys showed a graph of the per cent calories from fat in the food of various countries vs. the mean serum cholesterol levels. The data points fell on a straight line, showing an excellent correlation. Dr. Ravnskov added data points from a number of countries deliberately ignored by Dr. Keys. These fall nowhere near the line. Furthermore, CHD death rates among subjects in Finland, Greece and Yugoslavia with similar serum cholesterol levels varied 5-fold depending on which area of the country they lived in!

Four studies in the US, one in the UK, one in Israel and one in Finland failed to show any correlation between diet and serum cholesterol levels.

"Numerous studies have shown that in people who eat a normal Western diet, the effect on blood cholesterol of eating 2 or 3 extra eggs per day over a long period of time can hardly be measured..."

"To find out how egg consumption influenced my own blood cholesterol, I once used myself as a human guinea pig without asking the ethics committee at my university. Before and during the experiment I analyzed my [total serum] cholesterol. My usual egg consumption is one or two eggs per day, and my cholesterol value at the start of the experiment was 278 mg/dL, very close to a determination of blood cholesterol made 10 years earlier." On day 0, Dr. Ravnskov ate 1 egg; on day 1, 4 eggs; on day 3, 6 eggs; and on days 3-8, 8 eggs per day! "The data from my daring experiment showed that instead of going up, my cholesterol went down a little [to 246 mg/dL]."

"Myth 4: Cholesterol blocks arteries." "As early as 1953 Ancel Keys wrote: 'It is a fact that a major characteristic of the sclerotic artery is the presence of abnormal amounts of cholesterol in that artery.' And he added: 'This cholesterol is derived from the blood.' No proofs and no arguments - not from Keys and not from his followers. The cholesterol comes from the blood, and that's the end to it."

Dr. Ravnskov explains that older people have higher concentrations of cholesterol in their blood than younger people. If the serum cholesterol is graphed against the degree of atherosclerosis with all age groups lumped together, there seems to be a direct relationship. But if only people of about the same age and sex are considered, there is only a weak relationship with a correlation coefficient of 0.29. (A perfect correlation would have a correlation coefficient of 1.00.) When the subjects with familial hypercholesteremia are left out, even the weak correlation vanishes.

"The first study designed to demonstrate a possible correlation between blood cholesterol and degree of atherosclerosis was published by the pathologist Kurt Landé and the biochemist Warren Sperry of the Department of Forensic Medicine at New York University. The year was 1936. They studied large groups of individuals who had died violent deaths. To their surprise, they found absolutely no correlation between the amount of cholesterol in the blood and the degree of atherosclerosis..."

"Because Landé and Sperry were cautious and methodical, their study should have nipped the diet-heart idea in the bud. Or, more accurately, if those who promoted the diet-heart idea later on had read Landé and Sperry's paper before beginning their research, they would probably have dropped the idea at once... But the few who remember Landé and Sperry misquote them and claim that they found a connection, or they ignore their results by arguing that cholesterol values in the dead are not identical with those in the living..."

"In the city of Agra in India, Dr. K. S. Mathur and his co-workers performed a similar study [in 1961]. Their first step was to measure blood cholesterol in 20 patients shortly before death and then a varying number of hours afterwards. They found that the cholesterol values were nearly the same if samples [were taken] before death and within 16 hours afterwards. Thus, blood samples taken very shortly after death are reliable - an important confirmation of the study done by Drs. Landé and Sperry. Dr. Paterson's group in Canada did a similar test and obtained a similar result.

"Next Dr. Mathur and his colleagues studied 200 people who had died in an accident, without any preceding disease. Like Drs. Landé and Sperry, and like Dr. Paterson, the Indian researchers could find no connection between cholesterol values and the degree of atherosclerosis. Those with low cholesterol had just as much atherosclerosis as those whose cholesterol was high.

"Similar studies have also been performed in Poland, in Guatemala, and in the US, all with the same result: No correlation between the level of cholesterol in the blood stream and the amount of atherosclerosis in the vessels."

A report from the Framingham Study found a weak correlation coefficient, 0.36. Dr. Ravnskov found what distinguished this report from all the others he studied: only 14% of the Framingham dead were chosen for autopsy, not close to 100% as in the other studies. The risk of preferentially selecting subjects who probably had familial hypercholesteremia was said by Ravnskov to be great. To prove that high cholesterol is the villain - and not just an innocent bystander - demands that a change in the cholesterol concentration in each individual is followed by a change in degree of atherosclerosis in the same direction. Examination of all studies on this relationship showed no correlation.

"Myth 5: Animal studies prove the diet-heart idea." "When it comes to cholesterol, none of the other mammals is like us. They have other amounts of it in their blood, different dietary habits, and most of them do not become atherosclerotic.

"Many mammals never eat food containing cholesterol . If they are force-fed a cholesterol-rich diet, the cholesterol level of their blood rises to values many times higher than ever seen in normal human beings. And since such animals cannot dispose of the cholesterol they have eaten, every organ soaks up the cholesterol like a sponge soaks up water...

"Using cholesterol-rich fodder, it is possible to induce arterial changes that vaguely resemble human atherosclerosis in rhesus monkeys, but it was not possible in baboons. How do we know whether man reacts like a rhesus monkey or like a baboon or in some other way?...

"It is true that cholesterol is also deposited in the arteries of the [force-fed] rabbit, but these deposits do not even remotely resemble those found in human atherosclerosis. Cholesterol appears in different places in a rabbit's vessels than in man's, the microscopic changes are different, no hemorrhages or clefts appear as they do in man, and no thrombus or aneurysm formation in the arterial wall is seen. The most striking fact is that it is impossible to induce a heart attack in a rabbit by dietary means alone."

"Myth 6: Lowering your cholesterol will lengthen your life." Dr. Ravnskov reviewed the evidence presented earlier - that cholesterol levels in blood, or HDL or LDL levels, or the ratio of the latter are not correlated with either atherosclerosis or heart attack rates. It follows that forcible reductions of cholesterol levels by drugs (since diet alone does not change the levels much) would not be expected to change the rate of CHD. However, two things are possible with allopathic drugs. First, some unknown mechanism unrelated to cholesterol could lengthen lifespan. Second, some side-effect unrelated to cholesterol could shorten lifespan. The pervasive misconceptions about cholesterol has made it nearly impossible to carry out a placebo-controlled trial of new drugs because it is mistakenly considered unethical not to treat people with high cholesterol levels!

"In the 1960s, Professor Jeremy Morris of London, England, led a team of physicians and scientists in an investigation to see whether the replacement of animal fat with soybean oil could have some preventive effect on CHD. This oil is rich in polyunsaturated fatty acids, those that are considered [erroneously to be] protective against atherosclerosis and CHD. Enrolled in the trial were about 400 middle-aged men who had previously been admitted to 4 London hospitals because of a heart attack; half of these received a diet containing large amounts of soybean oil. (This is one of the few trials sponsored solely by a government, and not by a drug company or any other vested interest.)"

"When the researchers analyzed the results 4 years later, they could find no beneficial effects from using soybean oil. Although, in this particular trial, blood cholesterol had decreased considerably in the treatment group, 15 had died of a heart attack. In the control group, 14 had died; and the number of non-fatal heart attacks was the same in both groups." Other trials gave the same result.

These trials on patients who already had symptoms of CHD are called "secondary prevention" trials. Now Ravnskov describes some of the "primary prevention" work, that is, trials with healthy or, at least, symptomless patients. Much larger numbers of subjects are needed to obtain good statistical results, and compliance is always suspect because of the severe side-effects of many of the treatments or drugs used in subjects who are basically healthy, and thus may not be compliant because of lack of fear of poor health. When you recall the conclusions in Myth 2, that high cholesterol does not cause CHD, you will not be surprised at the negative findings now to be described.

In 1967 the Coronary Drug Project tested nicotinic acid, clofibrate, thyroid hormone, and estrogen to lower cholesterol levels in middle-aged men who had already had at least one heart attack. After 7 years the death rates were the same as that of the controls. Worse, all 4 drugs had severe side-effects. The researchers fell victim to the "surrogate endpoint". This is the use of an easily measured factor, such as total cholesterol level or blood pressure, as a surrogate or substitute for what is really important - increasing lifespan or the quality of life. In a later chapter Ravnskov calls this a "surrogate outcome".

In 1970 the Upjohn Co., Kalamazoo, MI, US, sponsored a trial with controls on 2000 men and women with high cholesterol of its then new drug colestipol. Two years later no effect was seen in the women. The number of heart attacks in the men in the treatment group was cut in half, a remarkable result never seen before or since. But Ravnskov found the snag: The selection of the patients to be in either the treatment or control groups was done by Upjohn's scientists with the results of the participants' blood assays in hand; it was anything but random. Ravnskov noticed that there were too many control patients with familial hypercholesteremia. Your reviewer notes that, in the 1996 Physicians Desk Reference entry for this drug, there is not a shred of evidence for longer lifespan; moreover, there were no restrictions on prescribing this drug for women.

For the World Health Organization trial, researchers assayed blood cholesterol in 30,000 healthy, middle-aged men in Edinburgh, Prague and Budapest. The 10,000 men with the highest blood cholesterol levels were selected for the trial, half to receive clofibrate, half placebo. After 5 years there were more fatal heart attacks in the clofibrate group. There were 128 total deaths in the clofibrate group and 87 in the placebo group. "Yet clofibrate is still recommended in many countries as a useful drug."!!

The Oslo, Norway, trial was shown to be typical of several such trials in that dietary advice to lower cholesterol intake, cessation of smoking and loss of weight were all varied at once. The barely significant difference in death rate - those in treatment did better than the control subjects - could not be assigned to any one factor.

The Multiple Risk Factor Intervention Trial (MRFIT) sponsored by the National Heart, Lung and Blood Institute (of the NIH, US) selected the 12,000 men considered most at risk for heart attack from 360,000 middle-aged men from 18 American cities. Those in treatment smoked less, took drugs for blood pressure, and ate less cholesterol. After 7 years the number of deaths from all causes was 265 in the treatment group and 260 in the control group! When a scientific experiment does not produce results supporting a hypothesis, the scientists are supposed to admit it immediately; such honorable actions have engendered respect for scientists. Not in this case, however. The researchers arbitrarily excluded the results from certain groups of subjects, changed the type of statistics used, and reported that MRFIT was a success in some media, according to Ravnskov, although not in the paper by O. Paul cited above.

The National Heart, Lung and Blood Institute embarked on a new jumbo trial called The Lipid Research Clinics Coronary Primary Prevention Trial (LRC) to test the effectiveness of cholestyramine (Bristol-Myers Squibb). To find about 4,000 test subjects, the 0.8% of 500,000 middle-aged men with the highest cholesterol levels were selected. All were given a few weeks of dietary indoctrination to solve the supposed ethical dilemma of not otherwise treating the controls. Half received cholestyramine and half placebo for 7-8 years. Of those treated, 190 (10%) had nonfatal heart attacks against 212 (11.1%) of the controls. For fatal heart attacks the figures were 1.7% and 2.3%, a difference of 0.6% absolute or 12 individuals. In the summary of the paper on this trial these unimpressive results were presented as a 19% lowering (relative risk) of nonfatal heart attacks and a 30% lowering of fatal heart attacks.

"And this was not the only way in which the LRC figures were manipulated. In order to reach their 30% figure, the LRC directors included the uncertain cases, those who may or may not have died from a heart attack, and to reach their 19% figure, they excluded the uncertain cases. If it had been the other way around the results would have been 24% rather than 30, and 15% rather than 19. In other words, they selected data that gave them the results they were seeking." Even worse, the directors abandoned the 99% confidence level with a 2-tailed t-test and settled for a 95% confidence level with a 1-tailed t-test. [In an end-note Ravnskov points out that scientists have agreed that a 1-tailed t-test should be used only when it is certain that the result will go in just one direction. It is not supposed to be used when the drug (or other intervention) may do harm rather than good.] Very revealing is the absence of the number of deaths from all causes. More men in the treatment groups died by violence or suicide (11 vs. 4). In the misleading manner used by the LRC to present results, they could have said that violent death was 175% more likely in the treatment group. In order to achieve essentially nothing, the treatment group suffered gas, heartburn, belching, bloating, abdominal pain, nausea and vomiting. The study's report assured readers that the side-effects were not serious. Some promoters then claimed that now that it had been proven that it is worthwhile to lower cholesterol no more trials were necessary!"

Ravnskov goes on to show that trials with a seemingly positive result are cited much more frequently than trials with a negative result. This gives a positive feedback effect, reinforcing the dogma than reducing cholesterol level is beneficial, but this sort of misdirected effort actually does not produce better health.

A study showed that patients treated with lovastatin and colestipol had their coronary arteries narrowed as shown by X-rays. The title of the paper on this study indicated the opposite: "Regression of coronary artery disease as a result of lipid lowering therapy..."

Ravnskov then presents the results of a meta-analysis of 26 cholesterol-lowering trials that met his standards. Result - no benefit.

Ravnskov presents the results of a number of trials of statin drugs in which total death rates are slightly lower than those of the controls. In an early trial of lovastatin (EXCEL) on 8,000 subjects the absolute death rate from all causes after just 1 year was 0.5% vs. 0.2% in the placebo group.

Your reviewer checked the report on the results of another study, this one lasting 5.2 years [Downs et al., J. Amer. Medical Assoc.279 (20), 1615-1622 (1998)]. There were no results given for death from all causes in this study, which was called AFCAPS/TexCAPS. So, even though lovastatin reduced the incidence of first coronary events by 37% in this trial, there is still not enough evidence to warrant using this drug. Nevertheless, Downs et al. suggest that 6 million Americans may benefit from LDL-cholesterol reduction by lovastatin!

Regarding studies carried out on lovastatin lasting 10 years, Ravnskov found no reports on total death rates. Ravnskov queried Merck & Co. directly and was told that the trial was not designed to measure the total clinical outcome!

Deaths from heart attacks were significantly lower in some trials of other statin drugs, but total deaths were 3% absolute lower at best. In the CARE trial Ravnskov showed that a 12% reduction in heart attacks (-1% absolute) was overbalanced by a 1500% increase in cases of breast cancer (+4% absolute). Total deaths were not given. Once again this shows that women should not be treated with statin drugs (or at all), and the benefit for men is quite limited at best with simvastatin and pravastatin.

The incidence of breast cancer was said to be a fluke, and was not observed in the LIPID trial lasting 6 years, in which overall mortality was said to be reduced by 22%; but this was relative risk, an overall drop in mortality of 3% absolute was achieved in subjects with a broad range of initial cholesterol levels [Tonkin et al., New England J. Medicine 339 (19), 1349-1357 (1998)].

In middle-aged men with hypercholesteremia treated with pravastatin for 5 years, death from all causes was reduced by 22%; but this was relative risk; an overall drop in mortality of 1% absolute was achieved [Tonkin et al., New England J. Medicine 333 (120), 1301-1307 (1995)].

"Myth 7: Polyunsaturated oils are good for you." Ravnskov tries to explain what the polyunsaturates are chemically. His effort is one of the few weak points in this book. The degree of saturation actually refers to whether hydrogen can be added to the oil. If so, some of the carbon-carbon bonds in the fatty acid portion of the oil molecule must have been double bonds in which 4 electrons are shared, rather than 2 electrons in the much more common single bonds. Olive and canola oils are the best examples of monounsaturated oils (a sole double bond in each fatty acid portion), and safflower, cottonseed and soybean are examples of polyunsaturates (two or more double bonds in each fatty acid portion). If hydrogen cannot be added in the presence of a catalyst, the oil (or more likely the fat) is said to be saturated, meaning that it cannot take up any more hydrogen. Palm and coconut oils are the best examples. Tallow, lard and chicken fat have some saturated and some monounsaturated fatty acids in their molecules.

Ravnskov cites a survey that showed that high consumption of polyunsaturates leads to premature aging. Also, researchers at a San Francisco, CA hospital thought that babies admitted with edema, anemia and blood cell disturbances were victims of commercial baby milk formulas containing skim milk and polyunsaturates.

Chickens fed polyunsaturates develop brain damage very quickly, but perhaps this should not be expected to apply to humans. A study cited in Myth 1 found that heart attack victims in Puerto Rico and in Honolulu consumed more polyunsaturated oils than those who had not had a heart attack.

The risk of eating transfats is presented at some length. (The reader may avoid transfats by not eating or drinking anything for which the words "partially hydrogenated" appear in the ingredients list.)

"Myth 8: The cholesterol campaign is based on good science." Ravnskov gives examples of reports of interventions with little or no statistical significance being denied time for presentation at meetings, and that offers to write minority dissenting reports on certain trials were being denied on the grounds that the conference was supposed to produce a consensus. Statements of diet-heart proponents and their recommendations are quoted followed by a Ravnskov's refutation of the claimed evidence. He reiterates that even drastic lowering of cholesterol levels with drugs (diet being ineffective) is of no benefit to women and of marginal benefit to men. Ravnskov presents arguments against trying to lower cholesterol levels in children.

"Myth 9: All scientists support the diet-heart idea." If Ravnskov were a lone voice among the Philistines his credibility would be lowered. In this chapter he gives the names of several of the scientists who support his position. This includes Mary Enig, President of the Maryland Nutritionists Association, whose research concerned the hazards of transfats, and who has written a book on the composition and effects of fats in the diet.

Michael Gurr, Professor of Biochemistry, School of Biological and Molecular Sciences, Oxford University, pointed out the insufficient correspondence in vascular pathology between animal models and man, the selection bias in epidemiologcal evidence, the lack of correlation between CHD and fat consumption, and the lack of improvement in coronary mortality after dietary and drug intervention.

George Mann, Professor of Medicine and Biochemistry at Vanderbilt University, TN, realized, from his studies of the Masai in Kenya, that animal fat could not possibly be the cause of high cholesterol and CHD, and he has been open and fearless in his criticism of the LRC directors, and has called the diet-heart theory "the greatest scientific deception of this century, perhaps of any century".

Michael F. Oliver, former Professor and Director of the Wynn Institute for Metabolic Research, London, UK, has warned against campaigns for cholesterol lowering in the general population; criticized those who think that the increased mortality from non-medical causes in trials, such as suicide, is due to chance; and is uneasy about the link between low cholesterol and cancer.

Edward R. Pinckney, editor of a number of medical journals, published a book in 1973 called The Cholesterol Controversy which summarized all the inconsistencies in the cholesterol literature, describes the dangers of lowering one's cholesterol , and devotes an entire chapter to the political drama preceding an early anti-cholesterol campaign.

Raymond Reiser is a former Professor of Biochemistry at Texas A & M University. He decried the practice of referring to other reviews, each taking the last on faith, which has led to the acceptance of a phenomenon (diet-heart) that may not exist. He reviewed work on fatty acids in the diet, found flaws in most of the studies, and concluded that the type of fat in the diet does not make much difference. He analyzed the references used by the American Heart Association in its rationale for dietary recommendations, and found no supportive studies, but instead, some that contradicted the recommendations.

Ray Rosenman is the retired Director of Cardiovascular Research in the Health Sciences Program at SRI International in Menlo Park, CA, and Associate Chief of Medicine, Mount Zion Hospital and Medical Center in San Francisco, CA. He has been a cardiologist and researcher since 1950. In a recent review he wrote that neither diet nor the identity of serum lipids (fats or oils) can explain wide national or regional differences in rates of CHD, or the 20th century variations in rates of CHD. Also that the CHD-preventive effects of diets and drugs have been exaggerated by a tendency in trial reports, reviews, and other papers to cite and inflate supportive results, while suppressing discordant data.

The late Russell Smith was an American experimental psychologist with a strong background in physiology, mathematics and engineering. In his 1989-91 review of the diet-heart theory he wrote: "...studies are often poorly designed and data are often inappropriately analyzed and interpreted... Much of the literature, therefore, is nothing less than an affront to the discipline of science..." He considered much of the work of the National Heart, Lung and Blood Institute and of the American Heart Association to be "incompetent" and "sloppy", and that their political and financial power is enormous and without equal, producing a juggernaut willing and able to suppress evidence and logic. "Equally culpable are the editors of the many journals who publish articles without regard to their quality or scientific import. It is depressing to know that billions of dollars and a highly sophisticated medical research system are being wasted chasing windmills."

William E. Stehbens, Professor at the Department of Pathology, Wellington School of Medicine, New Zealand, exposed the cholesterol myths in reviews: "...Scientific evidence for the role of dietary fat and [also] hypercholesterolemia in the causation of atheroscleosis is seriously lacking..."

Now retired, Lars Werkö, previously Professor of Medicine at Sahlgren's Hospital, Gothenburg, Sweden, Scientific Director at the Astra Co. (now Astra-Zeneca), and head of the Swedish Council on Technology Assessment in Health Care, criticized the design of the Framingham Study, and pointed out inaccuracies and sloppy data gathering in the MRFIT trial.

In the Introduction and Epilogue of this book, Dr. Ravnskov invites the reader to study original papers and follow the arguments. Without the detail he has provided, his voice might be considered "just another opinion". As it happens, a number of other physicians and scientists in addition to the ones in Myth 9 agree with his positions.

Linus Pauling, in his 1986 book: How to Live Longer and Feel Better, quotes John Yudkin, M. D., who found that the correlation between CHD and fat intake is not as good as the correlation with sugar intake. He noted that the Framingham Study showed no correlation between CHD and fat intake, or with cholesterol intake. However, Pauling was fooled by the study on cholestyramine, and failed to note total death rates.

Thomas J. Moore, a medical reporter based in Washington, DC, wrote an article in the September, 1989 issue of The Atlantic Monthly actually called The Cholesterol Myth in which he examined the literature much as Ravnskov did. Moore's conclusions: "Lowering your cholesterol is next to impossible with diet, and often dangerous with drugs - and it won't make you live any longer." This review was also used in Moore's 1990 book Heart Attack.

William Campbell Douglass, Jr., M. D., in 1993 wrote a brochure called Eat Your Cholesterol: How to Live off the Fat of the Land and Feel Great! This might still be available from Second Opinion Publishing, P. O. Box 467939, Atlanta, GA, 30346-9989. Many of the dietary studies and trials are the same ones evaluated by Ravnskov, but are treated in a very popular tone.

John B. Allred came to nearly all the same conclusions as Dr. Ravnskov in his article Lowering Serum Cholesterol: Who Benefits? in the Journal of Nutrition 123: 1453-1459 (1993).

Kilmer S. McCully, Ph. D., M. D., in technical papers and a book: The Heart Revolution: the Extraordinary Discovery that Finally Laid the Cholesterol Myth to Rest, Harper Perennial, 2000, wrote: "But no study anywhere has ever proven that lowering the amount of cholesterol in the diet reduces the risk of heart disease. And lowering cholesterol through drugs won't prevent arteries from hardening if homocysteine is high." McCully is the discoverer of the fact that the undesirable amino acid called homocysteine is an actual cause of atherosclerosis and CHD.

Based on Ravnskov's meticulous analyses as well as the considerable support for his stance shown by others who have also studied the cholesterol data, this book is recommended without reservation. Physicians and other health professionals as well as anyone threatened with cholesterol-lowering treatments would be enlightened, and better able to resist worthless treatments. Health insurers might reconsider compensation for frequent (or any) clinical assays for cholesterol or triglycerides, let alone expensive treatments to lower cholesterol levels that reduce quality of life without prolonging it significantly.

I think there is something to what the article says. My diet has always been high in fat, meats and dairy [I especially love bacon and ham and milk], yet my cholesterol levels have remained the same, quite low, over the years, and there's no evidence of heart disease. My doctor nearly had a heart attack, though, when I finally 'fessed up. I think there's probably a genetic component to heart disease, and probably other factors not yet understood.

"Newbury Naturals, Inc."

Is this starting to look like a quack rant or what?

You know I don't think there would be any lack of volunteers for a multi year study in which half get generous rations of steak and eggs, and half get to eat what is today considered a "balanced diet," if the food is furnished free. It shouldn't be that hard to hide the results. One thing which is not pointed out here is any connection to activity levels and/or exercise and/or overall weight (high fat tends to be high calorie, and saturated fat seems to be the easiest fat to get). And how about other nasties suspected, such as increased cancer rates for the susceptible. How about the "brown fat" and other genetic connections for some peoples with a high meat diet (e.g. the Eskimos), which makes them able to burn off more calories, and perhaps to deal with saturated fats better. This rant sounds like the data cherry pick it complains about itself.

Too much sugar weakens your immune system ... something that needs to be kept very strong these days.

There are also some indications that low-fat diets and Nutrasweet all contribute to widening the very tiny gaps between ganglia in the brain. These gaps must be small for the electrochemical reactions to occur that give us THOUGHT. Widening the gaps leads to inabilities to think, reason, remember, exert motor control over oneself, etc.

---------------------

A couple of decades ago, the Navy accidently discovered that ELF (extra-low frequency) radio waves immediately and dramatically increased the triglycerides in the bloodstream of those exposed. Triglycerides are what cause hardening of the arteries.

There are dozens of anecodotes of folks across the country being diagnosed for "tinitus" for a persistent ringing/humming sound heard. Taos, New Mexico is well-known for folks having to move away from it because of the persistent humming they hear.

One thing which is not pointed out here is any connection to activity levels and/or exercise and/or overall weight (high fat tends to be high calorie, and saturated fat seems to be the easiest fat to get).

Everyone seems to agree that a reasonable amount of exercise can only be good for you, and that total abstinence from exercise is not recommended.

As for weight loss/maintenance, the scientific evidence is irrefutable: it's solely a function of the calories consumed less the calories burned. This has been confirmed by numerous experiments. The advantage that fat calories have over carbohydrate calories is that they are more satisfying, and help you "feel full" longer. The evidence also shows that eating both fat and high fiber (low glycemic index) carbohydrates together results in the best and longest lasting feeling of satiety. Obviously, the less calories required to feel satisfied, the easier it will be to lose or maintain weight.

And how about other nasties suspected, such as increased cancer rates for the susceptible.

The evidence is quite clear that neither aturated fat nor monounsaturated are culprits when it comes to cancer. The reverse is true for polyunsaturated fats.

However, it may be that the chemicals formed when meat is cooked in certain ways cause cancer.

How about the "brown fat" and other genetic connections for some peoples with a high meat diet (e.g. the Eskimos), which makes them able to burn off more calories, and perhaps to deal with saturated fats better.

Anaerobic exercise (weight training) builds brown fat.

This rant sounds like the data cherry pick it complains about itself.

All information is always suspect. No theory or belief can ever be proven to be absolutely true, and is always subject to criticism and disproof. The best that can be done is to make one's best approximation based on the evidence currently available, but to also realize that revisions may be necessary in the future.

I read a study a number of years ago questioning why the farmers of Ireland - who ate a typical high-fat diet of bacon, butter, milk - did not die of heart disease.

I hang out around Santa Fe on occasion, and I have heard the humming, there, as well.

It waxes and wanes, but especially in the right kind of structures, the sound is a bit amplified by it seems, the nature of a roof --- it is sort of a drum head that resonates with the hum.

The hum is a lot like a railroad engine or river tow boat (uses the same engines by the way) heard through the ground from a very long distance.

For example, here in central Ohio, on a very calm night, I can hear the railroad engines at a freight yard, five miles away, when the engines are at idle.

Christmas day, bright and early, in 1993, I even detected a bad bearing in one of the engines. It was extremely cold outside, and nobody was on the road.

But I was determined to track down the sound coming from my bedroom wall.

I left the house and traveled west, occasionally stopping to get out of the car and give a listen.

Well, miles from here, I found a frieight train engine which a crew had left idling, and the engine had the bad bearing.

I left them a note on their windshield, regarding same.

Probably, the sound made its way here, because the whole area has an underlying limestone rock bed. The bed is lower, underground, near the freight yards, but it is exposed, here, where the soils are quite thin.

While I have not heard the humming in Taos, because I have not been up that way, I have heard the humming in the Santa Fe / Los Alamos area.

The caldera of which the mountain, Redondo, is prominent, making up part of a very large, and ancient volcano-appearing hole in the earth, and also next to which Los Alamos is built, might instead of being a "pure" volcano, actually be an ancient impact crater, where the crust was cracked well enough to evoke a volcanic reaction.

It much more looks like an impact crater --- very much like those on the moon.

Sometimes, it seems that whatever real impact that great meteorite had, the consequences still resound.

Perhaps.

Crisco is the original man-made "partially hydrogenated" fat--in other words, a trans-fatty acid. There is some concern that artificial trans-fatty acids may be especially harmful to cardiovascular health. There is much dispute over this issue. Personally, I'd rather be safe than sorry.

If that's the best you can do in terms of criticism than the article seems to have a lot to recommend it. It may say Newbury Naturals on the bottom but both the author and reviewer appear to have PhDs in science research.

For those who follow this stuff, Atkins has been criticized for a long time for not providing enough studies to support his data. He has been saying recently that those studies are coming and his critics will finally be silenced. This book looks like a step in that direction. I will read if for sure. I'm glad this was posted. Bump!

Too much sugar weakens your immune system ... something that needs to be kept very strong these days.

I much prefer the meat, Italian, beans & ham hock, chocolate malt and southern-style sugared tea diet... add enough garlic to the main courses and it reboots the immune system just fine (sugar or no sugar). The tannin in the tea cuts the carcinogens in the BBQed stuff, and the ham hocks deter terrorists, LOL.

"To find out how egg consumption influenced my own blood cholesterol, I once used myself as a human guinea pig without asking the ethics committee at my university. Before and during the experiment I analyzed my [total serum] cholesterol. My usual egg consumption is one or two eggs per day, and my cholesterol value at the start of the experiment was 278 mg/dL, very close to a determination of blood cholesterol made 10 years earlier." On day 0, Dr. Ravnskov ate 1 egg; on day 1, 4 eggs; on day 3, 6 eggs; and on days 3-8, 8 eggs per day! "The data from my daring experiment showed that instead of going up, my cholesterol went down a little [to 246 mg/dL]."

Probably true. They just found a natural lipid in eggs that blocks the absorption of 100% the cholesterol in the egg and probably anything else you eat with eggs.

And this morning I saw a blurb on TV about a study that links long distance running with heart disease, because of the resulting inflammation.

I have a low cholesterol count too. But I am almost a vegetarian. I eat mostly fish. Almost no beef or pork flesh. But I have eggs and butter and cheese. I don't care for the sweets either. Love the hot spicy stuff though. I read a book in the mid 80's that was actually written in the mid-70's about the subject of fats and cholesterol. Written by a doctor, don't recall the name right now, but he made very much sense on the subject. He said -- any fat, like margarine, which solidifies at room temperature is worse that butter. It is lacking in the nutrional value that butter has for one thing. And will clog arteries as likely as anything. He also pointed out the fallacy of believing that starchy foods which are fried in an unsaturated fat are better for you, as unsaturated fats will become saturated at high temperatures and make a bond with the starch molecules. As he put it -- think of it as a man with empty hands (unsaturated) and at a high temperature you are filling those hands with the starchy molecules. I personally think that worrying about it causes high cholesterol. Eat lots of green leafy veggies and fruits and forget about it. 8^)

Another thought on this. I also don't care for sodas. Cokes and stuff. I have believed for a while now that they cause a lot of the health problems people suffer. For one thing, you are consuming what -- carbon dioxide, and where does all that carbon go once our bodies have utilized the oxide part? I believe it ends up as plaque in our arteries and stones in our kidneys among other things. I could be wrong though.

Interesting. I don't care for sodas either. Do you think this business of our having low cholesterol, not liking sweets, preferring spicy foods, not liking sodas are all connected in some way? I eat meat like crazy, you're a vegetarian, but otherwise we have similar tastes, and we both have low cholesterol. By that I mean the bad cholesterol.

Actually, there IS a correlation mentioned in this piece--heart attacks went up at the same rate as radio and TV set acquisition. In short, becoming a couch potato, coupled with a relatively high-fat diet, is NOT good for your heart.
