The Cholesterol Myths by Uffe Ravnskov, MD, PhD
Consider for instance the finding by Dr.Harlan Krumholz of the Department of Cardiovascular Medicine at Yale University, who reported that old people with low cholesterol died twice as often from a heart attack as did old people with a high cholesterol.2 Supporters of the cholesterol campaign consistently ignore his observation, or consider it as a rare exception, the result of chance among a huge number of studies finding the opposite.
But it is not an exception; there are now a large number of findings that contradict the lipid hypothesis. To be more specific, almost all studies of old people have shown that high cholesterol is not a risk fact for coronary heart disease. This was the result of my search in the Medline database for studies addressing that question.3 Eleven studies of old people came up with that result, and a further seven found that high cholesterol did not predict all-cause mortality either, and more such studies have been published since then.
I have mentioned it before, but it is worth repeating, that more than 90 percent of those who die from a heart attack or a stroke have passed the age of 65. You may also recall that high cholesterol is not a risk factor for women, nor for a number of other population groups.
But there is more comfort for those who have high cholesterol. At least fifteen studies found that total mortality was inversely associated with either total or LDL-cholesterol, or both. This means that it is actually much better to have high than to have low cholesterol if you want to live to be very old.
