Derived from the soybean plant and refined into an isolated powder form, soy protein powder is a nutrition supplement gaining popularity. Soy products have typically been embraced by vegetarians and health-conscious consumers as a healthy source of protein, but convenience, versatility and studies showing the many health benefits have caused a steady increase in popularity among the larger population.
Versatile Soy Alternative
Soy products, such as tofu, tempeh, miso, soy milk and soy cheese, are widely available. However, many people find it difficult to become accustomed to the texture and flavor of these products. Soy protein powder is most often used to make a smooth and creamy shake that is easy to swallow. Most powders also contain added thickeners, sweeteners and flavors along with vitamins and minerals, making them more palatable with additional nutrition built in. Consumers have the option of adding fruit, juices, or flavored extracts to homemade soy protein shakes, making them extremely versatile to the tastes of the consumer. Requiring no refrigeration, soy protein powder can be stored dry at room temperature for extended periods of time, and portability is not compromised. As people seek out ways to incorporate quick healthy meals into their fast-paced lives, soy protein powders provide a worthy option.
Complete Protein
Because the human body cannot produce all amino acids essential to bodily function, you must get some types from the food you eat. Soy provides a full spectrum of all essential amino acids that your body needs and which it cannot produce on its own, making it a complete protein. With no cholesterol, low fat and all essential amino acids, soy can provide a healthier alternative and total replacement to animal proteins.
Eases Menopausal Symptoms
High levels of isoflavones found only in the soybean are also said to ease symptoms that occur in response to menopause, such as hot flashes. Perhaps even more profound are the effects found on soy's ability to prevent osteoporosis, caused by reduced bone density. According to a study by Bahram Arjmandi, Ph.D., leading researcher of the Department of Human Nutrition at the University of Illinois at Chicago, "We found that while bone density increased with the consumption of soy isolate, more importantly, bone quality was improved. This is very important to the growing population of Americans confronting the onset of osteoporosis."
Reduces Chronic Disease Risk
Some controversy exists surrounding the extent to which soy can benefit prevention of some chronic diseases such as cancer, but there is overwhelming agreement on its benefits related to cardiovascular disease. The U.S. Food and Drug Administration agreed in 1999 that consuming 25 g of soy protein a day as part of a diet low in saturated fat and cholesterol may reduce the risk of heart disease. It is important to remember that soy protein alone will not necessarily improve heart health, but when coupled with a healthy diet, it is been shown to produce significant positive results.
