Soy may also be effective in other ways to prevent some types of heart disease. It may reduce or delay atherosclerosis (hardening of the arteries) by blocking an enzyme that causes blood vessels to lose flexibility. As a result, blood vessels may not get as stiff and plaques:deposits of blood cells and fatty substances that contribute to hardening of the arteries? may be less likely to form. Chemicals in soy may decrease the tendency of blood components known as platelets to cluster or aggregate. This ?thinning? of the blood also makes the formation of blood clots and plaques less likely. In addition, soy is thought to reduce levels of homocysteine in the body. Homocysteine is an amino acid produced from the breakdown of meat proteins in the body. Although a definite relationship has yet to be established, high levels of homocysteine in the blood have been linked with a higher risk of several conditions ? including coronary heart disease.
Soy also contains chemicals called isoflavones, which belong to a larger class of plant chemicals known as phytoestrogens. Two of the main isoflavones in soy are known as genistein and daidzein. Because they are shaped like the female hormone estradiol, soy isoflavones attach to estrogen receptors throughout the body -- particularly in the bladder, blood vessels, bones, and heart. For women with normal estrogen levels, soy isoflavones may displace some of the natural estrogens, thus possibly preventing the development of estrogen-dependent cancers of the breast and endometrium. In post-menopausal women, who have generally low blood levels of estrogen, soy may act as hormone replacement, thereby relieving some of the symptoms associated with low estrogen levels. The observation that Oriental women, who generally eat large amounts of soy as compared to women in western societies, have fewer hot flashes and other symptoms of menopause seems to confirm this theory.
Clinical studies have been inconclusive, however, in determining whether or not soy isoflavones are effective at relieving hot flashes associated with menopause. Some study participants experienced various degrees of relief from hot flashes, while others observed no change. In addition, soy isoflavones may actually accelerate the growth of existing breast tumors. More study is needed to determine whether soy is cancer-preventive for women and whether symptoms of menopause may be relieved by soy.
