Evidence for the Lipid Hypothesis: Review of Ignore the Awkward : Is Dr. Ravnskov als...: OBSERVATIONAL EVIDENCE 1. Michael Brown and Joseph Goldstein discovered that the number of functional LDL receptors on the surface of cells...

Here's one of my favorite quotes from this excellent Blog -

"6. Atherosclerosis can be induced in a great variety of animal species including vegetarian and carnivore species (e.g. insects, birds, cats, dogs, non-human primates etc.) by raising serum cholesterol high enough and maintaining it long enough. Atherosclerosis can also be reversed by lowering TC enough and maintaining it long enough. The lipid deposits and foam cells disappeared but some fibrous tissue remained. Some species, such as the dog and rat, do not get elevated TC from a diet high in saturated fat and cholesterol. But when a way was found to elevate their TC they also developed atherosclerosis. This is so consistent no matter which species is tested that it appears to be a scientific law that elevated LDL can cause atherosclerosis.' (Emphasis Added)

Here's another quote from the Blog -

"12. In Chapter 3, Dr. Ravnskov was not thinking clearly when he tells us that people with familial hypercholesterolemia (FH) live just as long as others. In the study he cites to make this claim
it clearly says that the FH patients were taking statins.  3)" (Emphasis Added)

Here's a quote from this EXCELLENT BLOG -

"In a later review, Keys again addressed Yudkin’s claims regarding sugar intake and coronary heart disease in international comparisons:4
In regard to international comparisons, there are countries with a high per capita consumption of sugar and of saturated fats; those countries tend to have high CHD death rates. And there are countries with low per capita sugar and saturated fat intakes; these have low CHD rates. When all these countries are put together, statistical calculation naturally shows CHD mortality is correlated with both sugar and fat intake. However, partial correlation analysis shows that when sugar is held constant, CHD is highly correlated with per capita saturated fats in the diet but when fat is constant there is no significant correlation between sugar in the diet and the CHD incidence rate. It should be noted, too, that Yudkin carefully avoids mentioning the fact that 2 countries with the highest per capita sugar consumption, Cuba and Venezuela, suffer low CHD mortality; it is notable that the dietary intake of estimated fats is low in both Cuba and Venezuela
Another flaw in Yudkin’s hypothesis about sugar and coronary heart disease that Plant Positive addressed was the contradictory evidence from animal experiments of atherosclerosis. When diets rich in dietary cholesterol and saturated fat, such as egg yolks are used to induce atherosclerosis in non-human primates, the atherosclerosis process has actually been reversed when these atherogenic components are replaced with chow very rich in sugar.5 6 This does not suggest that sugar should be considered a heart healthy food, but does emphasize the fact that sugar alone cannot induce atherosclerosis in the absence of dietary cholesterol and elevated blood cholesterol, and therefore cannot not explain the coronary heart disease epidemic."
