Supplement manufacturers have done a great job to confuse the ability of public research. Over the last 5 years bodybuilding community has absorbed whey protein.
Second, research has shown that due to its characteristics of rapid emptying of the stomach, most of the proteins of whey protein is metabolized and burned in the liver. Manufacturers of casein initially reacted by increasing the number of grams per serving. Why not? More proteins should be consumed to sell more protein.

Soy is very popular between vegetarians. Consider a manufacturer selling whey protein soy milk together, and to enter their piece of cake, went to the "health" of the market, particularly women. Many studies show soy producers are valid, but not the whole picture.

Feed in a special study, 2 groups of men with a group of intake of soy and the inclusion of other animal products as a source of protein. The idea was that if there was a lower incidence of gallstones, when soy protein replaced animal protein. Since the accumulation of gallstones are often related to the crystallization of cholesterol, the conclusion, we examined the studies, cholesterol.

Crystallization of cholesterol was slower than the group of soy consumption. This brought the idea that soy is to prevent gallstones. Unfortunately, the study did not respond to an important point. There was no control for vegetables. Soy is a plant and is rich in isoflavones.

Isoflavones are very close too many health benefits, including reduction of cholesterol associated. On the other hand, we have sometime, eating meat is a high level of cholesterol is linked. This does not mean that person who consume cholesterol levels better than men soy, chicken, turkey, eggs, fish and vegetables to eat will have. This clearly demonstrates that the conclusions drawn from studies, which are often out of context and exaggerated.

Numerous studies show the benefits of resistance of the plan vegetable diet severely from cancer, so we cannot understand that person, instead of soy milk, egg and animal proteins, better health, so exercise is part of the results in a plan cannot always be declared invalid.

Most research is funded through the soybean issued by companies with a financial interest in the sale of soy protein. The Board of soybean is a good example. Very often, the elements of a boutique firm out of context, to promote the sale of soybeans.
As for the metabolic benefits as reported on the latest studies and apply if the extra protein Off You're best of arrival, which are a mixture of whey and casein. View the last feature of protein supplements on the market in the mixture. If you are not vegetarian, I suggest it is better to continue to include a variety of foods as possible in your diet. If this is a daily supplement of soy protein contains, I think he is doing very well.
