Homocysteine is a destructive amino acid that can build up in the blood, leading to arteriosclerosis and a host of other degenerative diseases. B vitamins prevent this buildup, and these are the very nutrients lacking in the average diet. Dr. Kilmer McCully shows why our vitamin-B-depleted food supply-and not cholesterol-is the real culprit behind heart disease. In this extraordinary book, he explains the science behind his theories, then lays a safe, effective plan that shows readers how to: - Cut their risk of heart attack-without dangerous cholesterol-lowering drugs- Stop arteriosclerosis in its tracks-and perhaps reverse moderate heart disease- Add B vitamins to their diet, simply and deliciously, thereby lowering homocysteine levels.
