Soy Protein have been used for centuries in Asia as a nutritional source and also as a medicine. Despite this, the first use of soy formula in the U.S. was in 1909, and at which time, the soy protein based formulas used soy flour, which often caused gastrointestinal problems. It wasn't until mid 1960 that a soy protein isolate was used, reducing these problems.
Then in October 1999 soy protein products got a big boost when FDA approved manufacturers to label their soy protein products stating soy protein products help reduce the risk of heart disease.
Soy protein is a complete protein that ranks right up there with the best in the Protein Digestibility Corrected Amino Acid Score (PDCAAS). Soy protein is generally very low in or free of fat, cholesterol, and lactose.
Soy protein is approved for those who are lactose intolerant, and can be used as a meat substitute. Much more than just an ingredient for a protein shake, soy protein can be used for cooking instead of flour, producing high protein foods that are extremely low in fat…an ideal ingredient! Soy protein is derived exclusively from soy beans.
Soy protein provides a healthy way to get non-animal protein into your diet. It is great tasting, natural and can have a plethora of healthy effects on the body. It is ideal for high protein/low carb diets! It's valuable constituents include saponins, phytosterols, and isoflavones. This is one of the best things about soy protein! Saponins enhance the immune system's function and combine with cholesterol to reduce it's absorption into the body through the small intestine.
You can either get soy protein from the foods you eat, or if you're not into soy products, you can get soy protein powder supplements. Below are some most common sources of soy protein:
Tofu - there are several types of tofu such as soft tofu, firm tofu, and dried tofu. Visit tofu recipes for some very good tofu recipes.
Soy Milk - also called soy bean drink, is made by grinding soybeans and mixing with water. The ones you buy will usually be sweetened, and taste very good, but you can also get un-sweetened soy milk - or better yet, make it yourself with an automatic soymilk maker.
Miso - is a fermented soybean paste that's just mainly for seasoning in Japanese soup.
Soy Flour - made from grinded soy beans. Can be used in baked foods.
