Myths & Truths About Nutrition

Myth: Heart disease in America is caused by consumption of cholesterol and saturated fat from animal products.

Truth: During the period of rapid increase in heart disease (1920-1960), American consumption of animal fats declined but consumption of hydrogenated and industrially processed vegetable fats increased dramatically. (USDA-HNI)

Myth: Saturated fat clogs arteries.

Truth: The fatty acids found in artery clogs are mostly unsaturated (74%) of which 41% are polyunsaturated. (Lancet 1994 344:1195)

Myth: Vegetarianism is healthy.

Truth: The annual all-cause death rate of vegetarian men is slightly more than that of non-vegetarian men (.93% vs .89%); the annual death rate of vegetarian women is significantly more than that of non-vegetarian women (.86% vs .54%) (Am J Clin Nutr 1982 36:873)

Myth: Vitamin B₁₂ can be obtained from certain plant sources such as blue-green algae and soy products.

Truth: Vitamin B₁₂ is not absorbed from plant sources. Modern soy products increase the body's need for B₁₂. (Soybeans: Chemistry & Technology Vol 1 1972)

Myth: For good health, serum cholesterol should be less than 180 mg/dl.

Truth: The all-cause death rate is higher in individuals with cholesterol levels lower than 180 mg/dl. (Circulation 1992 86:3:1026-1029)

Myth: Animal fats cause cancer and heart disease.

Truth: Animal fats contain many nutrients that protect against cancer and heart disease; elevated rates of cancer and heart disease are associated with consumption of large amounts of vegetable oils. (Fed Proc July 1978 37:2215)

Myth: Children benefit from a low-fat diet.

Truth: Children on low-fat diets suffer from growth problems, failure to thrive & learning disabilities. (Food Chem News 10/3/94)

Myth: A low-fat diet will make you "feel better . . . and increase your joy of living."

Truth: Low-fat diets are associated with increased rates of depression, psychological problems, fatigue, violence and suicide. (Lancet 3/21/92 v339)

Myth: To avoid heart disease, we should use margarine instead of butter.

Truth: Margarine eaters have twice the rate of heart disease as butter eaters. (Nutrition Week 3/22/91 21:12)

Myth: Americans do not consume enough essential fatty acids.

Truth: Americans consume far too much of one kind of EFA (omega-6 EFAs found in most polyunsaturated vegetable oils) but not enough of another kind of EFA (omega-3 EFAs found in fish, fish oils, eggs from properly fed chickens, dark green vegetables and herbs, and oils from certain seeds such as flax and chia, nuts such as walnuts and in small amounts in all whole grains.) (Am J Clin Nutr 1991 54:438-63)

Myth: A vegetarian diet will protect you against atherosclerosis.

Truth: The International Atherosclerosis Project found that vegetarians had just as much atherosclerosis as meat eaters. (Lab Invest 1968 18:498)

Myth: Low-fat diets prevent breast cancer.

Truth: A recent study found that women on very low-fat diets (less than 20%) had the same rate of breast cancer as women who consumed large amounts of fat. (NEJM 2/8/96)

Myth: The "cave man diet" was low in fat.

Truth: Throughout the world, primitive peoples sought out and consumed fat from fish and shellfish, water fowl, sea mammals, land birds, insects, reptiles, rodents, bears, dogs, pigs, cattle, sheep, goats, game, eggs, nuts and milk products. (Abrams, Food & Evolution 1987)

Myth: Coconut oil causes heart disease.

Truth: When coconut oil was fed as 7% of energy to patients recovering from heart attacks, the patients had greater improvement compared to untreated controls, and no difference compared to patents treated with corn or safflower oils. Populations that consume coconut oil have low rates of heart disease. Coconut oil may also be one of the most useful oils to prevent heart disease because of its antiviral and antimicrobial characteristics. (JAMA 1967 202:1119-1123; Am J Clin Nutr 1981 34:1552)

Myth: Saturated fats inhibit production of anti-inflammatory prostaglandins.

Truth: Saturated fats actually improve the production of all prostaglandins by facilitating the conversion of essential fatty acids. (Price-Pottenger Nutrition Foundation Journal 20:3)

Myth: Arachidonic acid in foods like liver, butter and egg yolks causes production of "bad" inflammatory prostaglandins.

Truth: Series 2 prostaglandins that the body makes from arachidonic acid both encourage and inhibit inflammation under appropriate circumstances. Arachidonic acid is vital for the function of the brain and nervous system. (Price-Pottenger Nutrition Foundation Journal 20:3)

Myth: Beef causes colon cancer

Truth: Argentina, with higher beef consumption, has lower rates of colon cancer than the US. Mormons have lower rates of colon cancer than vegetarian Seventh Day Adventists (Cancer Res 35:3513 1975)

"Conclusions Despite the contribution of dairy products to the saturated fatty acid composition of the diet, and given the diversity of dairy foods of widely differing composition, there is no clear evidence that dairy food consumption is consistently associated with a higher risk of CVD. Thus, recommendations to reduce dairy food consumption irrespective of the nature of the dairy product should be made with caution"

From 3 men in a boat

I remember going to the British Museum one day to read up the treatment for some slight ailment of which I had a touch - hay fever, I fancy it was. I got down the book, and read all I came to read; and then, in an unthinking moment, I idly turned the leaves, and began to indolently study diseases, generally. I forget which was the first distemper I plunged into - some fearful, devastating scourge, I know - and, before I had glanced half down the list of "premonitory symptoms," it was borne in upon me that I had fairly got it.

I sat for awhile, frozen with horror; and then, in the listlessness of despair, I again turned over the pages. I came to typhoid fever - read the symptoms - discovered that I had typhoid fever, must have had it for months without knowing it - wondered what else I had got; turned up St. Vitus's Dance - found, as I expected, that I had that too, - began to get interested in my case, and determined to sift it to the bottom, and so started alphabetically - read up ague, and learnt that I was sickening for it, and that the acute stage would commence in about another fortnight. Bright's disease, I was relieved to find, I had only in a modified form, and, so far as that was concerned, I might live for years. Cholera I had, with severe complications; and diphtheria I seemed to have been born with. I plodded conscientiously through the twenty-six letters, and the only malady I could conclude I had not got was housemaid's knee.

I felt rather hurt about this at first; it seemed somehow to be a sort of slight. Why hadn't I got housemaid's knee? Why this invidious reservation? After a while, however, less grasping feelings prevailed. I reflected that I had every other known malady in the pharmacology, and I grew less selfish, and determined to do without housemaid's knee. Gout, in its most malignant stage, it would appear, had seized me without my being aware of it; and zymosis I had evidently been suffering with from boyhood. There were no more diseases after zymosis, so I concluded there was nothing else the matter with me.

I sat and pondered. I thought what an interesting case I must be from a medical point of view, what an acquisition I should be to a class! Students would have no need to "walk the hospitals," if they had me. I was a hospital in myself. All they need do would be to walk round me, and, after that, take their diploma.

Then I wondered how long I had to live. I tried to examine myself. I felt my pulse. I could not at first feel any pulse at all. Then, all of a sudden, it seemed to start off. I pulled out my watch and timed it. I made it a hundred and forty-seven to the minute. I tried to feel my heart. I could not feel my heart. It had stopped beating. I have since been induced to come to the opinion that it must have been there all the time, and must have been beating, but I cannot account for it. I patted myself all over my front, from what I call my waist up to my head, and I went a bit round each side, and a little way up the back. But I could not feel or hear anything. I tried to look at my tongue. I stuck it out as far as ever it would go, and I shut one eye, and tried to examine it with the other. I could only see the tip, and the only thing that I could gain from that was to feel more certain than before that I had scarlet fever.

I had walked into that reading-room a happy, healthy man. I crawled out a decrepit wreck.

I went to my medical man. He is an old chum of mine, and feels my pulse, and looks at my tongue, and talks about the weather, all for nothing, when I fancy I'm ill; so I thought I would do him a good turn by going to him now. "What a doctor wants," I said, "is practice. He shall have me. He will get more practice out of me than out of seventeen hundred of your ordinary, commonplace patients, with only one or two diseases each." So I went straight up and saw him, and he said:
"Well, what's the matter with you?"

I said:
"I will not take up your time, dear boy, with telling you what is the matter with me. Life is brief, and you might pass away before I had finished. But I will tell you what is NOT the matter with me. I have not got housemaid's knee. Why I have not got housemaid's knee, I cannot tell you; but the fact remains that I have not got it. Everything else, however, I HAVE got."

And I told him how I came to discover it all.

Then he opened me and looked down me, and clutched hold of my wrist, and then he hit me over the chest when I wasn't expecting it - a cowardly thing to do, I call it - and immediately afterwards butted me with the side of his head. After that, he sat down and wrote out a prescription, and folded it up and gave it me, and I put it in my pocket and went out.

I did not open it. I took it to the nearest chemist's, and handed it in. The man read it, and then handed it back.

He said he didn't keep it.

I said: "You are a chemist?"

He said: "I am a chemist. If I was a co-operative stores and family hotel combined, I might be able to oblige you. Being only a chemist hampers me."

I read the prescription. It ran:

"1 lb. beefsteak, with
1 pt. bitter beer every 6 hours.
1 ten-mile walk every morning.
1 bed at 11 sharp every night.
And don't stuff up your head with things you don't understand."

I followed the directions, with the happy result — speaking for myself — that my life was preserved, and is still going on.
