Vitamin B6

One of the most tragic medical blunders of the past few decades is the incorrect dogma that coronary artery disease -- and resultant heart attacks -- are caused primarily by cholesterol and "artery clogging fat." Yes, arteries clogged with plaque (which contains cholesterol and fat) can result in heart attacks, but there is abundant evidence that the mere presence of cholesterol and fats in the body does not, by itself, cause arterial plaque to form. In fact, many slender people with "ideal" cholesterol levels have plaque-filled arteries which result in heart attacks.

What medical dogma has overlooked until quite recently is that plaque builds up only in arteries that have been wounded in some fashion. Arterial plaque is, in essence a form of scab that forms on wounded arteries to protect us from internal hemorrhaging. What causes wounded arteries? One cause is free radicals, which can be combatted by antioxidants.

But a second major cause of arterial wounding -- and arterial plaque -- was discovered by the author of this book, Dr. Kilmer McCully: elevated concentrations in the blood of a chemical called homocysteine. Homocysteine is a natural product of the metabolism af an amino acid called methionine and, therefore, our body's always contain some homocysteine.

Vitamins B6, B12, and folic acid keep blood concentrations of homocysteine low enough to be safe.

But deficiency of these vitamins can allow homocysteine to build up to concentrations that can wound our arteries and lead to the formation of arterial plaque -- which can eventually trigger a heart attack. Recent research has confirmed Dr. McCully's findings. If you want to understand the role of homocysteine in causing cardiovascular disease and resultant heart attacks -- and learn how to protect yourself from them -- I strongly suggest that you acquire and read this valuable book. - D.
