Soy protein is a byproduct of the soya bean, which has been grown in Asia for hundreds of years. There are two kinds of soy protein: the concentrate and the isolate. Soy protein is highly digestible and is similar to milk and meat as a protein source, according to the Truestar Health website.
Benefits
There are several benefits of soy protein powder. According to the website, soy protein aids in enhancing nutritional value of foods, decreases cholesterol and is suitable for vegetarians. Twenty-five grams of soy protein a day, along with a diet low in cholesterol and saturated fat, may lower the chance for coronary disease, according to the Soya website. Soybeans contain isoflavones, which can help alleviate the symptoms of menopause and assist with bone maintenance.
Downside
While soy protein powder has health benefits, it also has drawbacks. Soy protein possesses anti-nutrients that hinder the digestion and assimilation of nutrients. Also, a Harvard School of Public Health study showed that men who use soy products had lowered traces of sperm and are "less likely to father children and more likely to experience the loss of libido."
Incorporation
Soy protein powder can be incorporated in different methods. The protein powder comes in a variety of flavors such as plain, unflavored, vanilla, chocolate and strawberry. The powder can be used in creating homemade protein shakes. The protein can also be added to cereal, oatmeal or soup. When making breads, muffins or other baking goods, protein powder can be added.
History
Soy protein dates back to Asia as a source of nutrition and as a medication. Soy protein was introduced in the United States in the early 1900s when the soy protein formula was made from soy flour, but often was responsible for stomach problems, according to Wellness.com. During the 1960s, a soy protein isolate was manufactured, decreasing stomach ailments. The U.S. Federal Food and Drug Administration sanctioned manufacturers to label products, stating they lower the chances for heart disease.
