Soy protein powder is a dietary supplement that can be used for a variety of reasons. There are numerous possible health benefits to be gained by adding soy to one's diet; however, not everyone prefers to consume it in forms such as tofu or soy milk. By using the powder added to juices, shakes, or other beverages, people can still enjoy the benefits of soy without having to eat soy-based foods.
There is evidence that soy has properties that can help prevent a variety of diseases and contribute to overall health. It contains antioxidants known as isoflavones which may help those who eat it avoid some types of cancer, heart disease, and osteoporosis. It is also high in several nutrients, including B vitamins, calcium, and magnesium, so it can help supplement diets lacking in them. Adding soy protein powder into one's diet can allow a person to take advantage of all of these benefits.
Those looking for an alternative source of protein may look to use soy protein powder. For example, vegetarians and vegans looking for meat-free protein alternatives may find these supplements useful. People who do not like meat or other protein-rich foods might also include soy powder in drinks to get enough of it in their diets. Since soy is very low in fat and cholesterol, using it to replace other, less healthy forms of protein may help some people improve their overall diet.
Bodybuilders who want to increase their protein intake sometimes use soy protein powder. Since one of the main goals of these athletes is to build up muscle mass, and protein is vital to doing so, they need to consume a high amount of it. Soy contains all of the essential amino acids that humans need, so it is a good source of additional protein that is easy to add into one's diet. Combining it with a whey protein supplement may provide even more advantages.
People who are underweight may also consider adding soy protein powder into their diets to gain weight. Though not significantly high in calories by itself, drinking it in addition to one's normal daily intake can help a person gain pounds. Those who are not looking to gain weight should use care in adding it to their diets; it is fine as a meal replacement but may bring unwanted results if no other calories are removed.
