Discover How Soy Protein Benefits Health

By Beryl Dalton


People who are allergic to dairy products or have chosen not to eat meat often rely on soy as an alternative source of protein. This substance is derived from the soybean which is native to southeast Asia, and besides proteins it is also packed with lecithin, fiber, and isoflavones, all of which promote good health. A diet that includes food and supplements containing soy protein benefits many systems of the body.

A very versatile food product, soy can be enjoyed in so many different ways. A popular base for powdered shakes, it is also the most common ingredient used instead of meat or dairy to manufacture food such as cheese, butter, milk, yogurt, ice cream, hot dogs, and tofu. It can be ground into flour which is then used as a sausage filler, or ingredient in soups, and baked goods. Babies who are lactose-intolerant, are often fed a soy-based formula.

There has been some research conducted which suggests there is a connection between consuming high amounts of dietary soy, and protection from some forms of cancer, namely breast and prostate cancers. This is believed to be due to the effect of a phytochemical known as "genistein" which works to prevent tumors from vascularizing, thus halting their growth.

Cardiac health is also improved. It is believed that the phytoestrogens and isoflavones it contains are responsible for the dilation of coronary arteries, which keeps blood flowing properly through the heart and cuts the risk for myocardial infarction. This can also result in regulation of healthy blood pressure and keep it at safe levels in patients afflicted with hypertension.

People who regularly consume soy-rich food or supplement shakes may have lower LDLs, which is the harmful or "bad" type of cholesterol. Apparently the soy protein breaks down the plasma in LDL cholesterol, but fortunately this does not happen with the healthier HDL cholesterol. Existing research has revealed this to be true mainly in men, who can expect their LDL levels to be reduced by up to 10 percent, but more research is required to prove whether the same is true in women or not.

People who are trying to lose weight as well as diabetics who need to keep their blood glucose levels in check can also benefit from the intake of this powerful protein. Levels of glucose, insulin, and fat in the blood is aided in its regulation by the ingestion of soy-rich foods or supplementary shakes. Weight control is made easier, as the proteins are slow to digest and help one feel full for a longer time, reducing the tendency to overeat.

Women going through menopause have also shown some positive health effects when increasing the amount of these nutrients they consume. Improvement has been noted in the reduced incidence of hot flashes in some women. It is also understood to promote the balance of calcium and bone density, which is needed to prevent osteoporosis in women who are post-menopausal.

Soy-shakes are highly recommended for the daily program of athletes, bodybuilders, and anyone else who wants to gain lean muscle tissue and boost their physical performance. It helps to reduce inflammation in the muscles following a workout, which leads to faster recovery, less pain after exercising, and ultimately maximum muscle development.
