Re: Are Polyunsaturated Fats really good ? -Part Two.

[Guest guest]

Well, 1) I don't accept the chart on human fat. That depends on what the human eats. Surely, that can be modified at least slightly by diet selection. HF might be mostly 16:0 if we eat no animal or vegetable fat. So what?

We're dealing with the lowest calorie intake, and hopefully that will produce the lowest incidence of all diseases.

Mostly the article is not congruent, eg, the people who consume an inordinate amount of soy oil do not have a shabby health record (US).

I question the inference to Ancel Keys. I have his book: "Eat well and stay well" CW 1959,1963. Page 38/39: "..while saturated fats raise the serum cholesterol level, some lipid oils, those rich in poly-unsaturated fatty acids, tend to depress it. .......The favorite of the oils ....... is safflower oil because it is very low in saturated fats (5 to 10 %) and very high in poly-unsaturated fats ( up to 80 %). .... These preparations are not dangerous and when use in fairly generous amounts, at least an ounce ... daily, will generally have some effect in lowering the blood cholesterol. ... oils are full of calories ...so the diet must be adjusted also. ... We think it far better to incorporate such materials in the regular diet."

Page 42/43,

"1. If you are fat, reduce.

2. Restrict use of fats in dairy products and in ordinary meats.

3. Use vegetable oils in cookery, not as medicine.

4. Avoid hydogeanted products but if you insist on a spread, use the newer margarines.

5. Avoid heavy use of salt and sugar.

6. Favor fish, shellfish, poultry, fresh vegetables, fruits, non-fat milk products.

7. Do not depend on the drugstore or vitamin peddlers for a good diet.

8. Be sensible about cigarettes, alcool, excitement, business strain.

9. Get polenty of exercie, with recreation and work out-of-doors.

10. Learn more about cookery and have fun without saturation."

Regards.
