What Causes Heart Disease?
by Sally Fallon and Mary G. Enig, PhD
For almost forty years, the lipid hypothesis or diet-heart idea has dominated medical thinking about heart disease. In broad outlines, this theory proposes that when we eat foods rich in saturated fat and cholesterol, cholesterol is then deposited in our arteries in the form of plaque or atheromas that cause blockages. If the blockages become severe, or if a clot forms that cannot get past the plaque, the heart is starved of blood and a heart attack occurs.
Many distinguished scientists have pointed to serious flaws in this theory, beginning with the fact that heart disease in America has increased during the period when consumption of saturated fat has decreased. "The diet-heart idea," said the distinguished George Mann, "is the greatest scam in the history of medicine."And the chorus of dissidents continues to grow, even as this increasingly untenable theory has been applied to the whole population, starting with lowfat diets for growing children and mass medication with cholesterol-lowering drugs for adults.
But if it ain't cholesterol, what causes heart disease? We don't know enough to say for sure but we do have many clues; and although these clues present a complicated picture, it is not beyond the abilities of dedicated scientists to unravel them. Nor is the picture so complex that the consumer cannot make reasonable life-style adjustments to improve his chances.
