A basically sound program for improving cardiovascular health with one very experimental component: a ""Formula"" of nutritional supplements to keep blood yessels clear of disease-causing deposits. Medical-researcher Morrison is primarily addressing those who, like himself, are at serious risk of cardiovascular disease because of family history--and his main message is prevention. He explains the physiological processes behind blood-vessel disease, and also looks at the well-established preventable causes of its development. All these causes receive adequate attention here: dietary factors; the need for exercise; less use, or elimination of, alcohol, caffeine, and tobacco; finding healthy ways to deal with stress. But Morrison's special advice is on the benefits of a dietary supplement which he claims--with apparent reason--helps the body keep its blood vessels clear of deposits that result from high fat intake, sedentary lifestyles, and certain other factors. The scientific evidence is set forth, in short, that a mixture of lecithin, choline, and other ingredients is beneficial to cardiovascular health: a fairly hot item in medical research. Morrison also effectively refutes studies that found such a mixture not effective, pointing out where poor experimental design and other confounding factors were involved. He freely admits, too, that his formula is still experimental. But since Morrison includes the basics of a healthy cardiovascular lifestyle, and the supplements would be unlikely to cause any harm, readers especially at risk stand to benefit by exploring the topic with their physicians.
