Soy Protein vs Whey Protein: The Battle Begins!“ In
the battle of soy protein vs whey protein there are many people
that really just want to know which is better for them, and for those
that are looking at building muscle, which protein is going to help
them the most.”
First understanding what the difference between soy proteins vs whey proteins is important. Whey protein comes from cow’s milk, usually a by-product of cheese. There are two proteins in milk casein and whey. Of the two the whey is the more soluble of the proteins and is considered to be a higher quality protein. Whey protein has for a long time been considered to be the most nutritious protein there was. Soy protein is made from leguminous soybeans. Soybeans have been a part of the food chain for more then 5000 years. Therefore soy protein is not a newly created protein, it is however the only plant protein available that is considered a protein of high quality. This qualification would first make the battle of soy protein vs whey protein somewhat equal. Standard wise they are both high quality proteins. Soy protein however offers all of the essential amino acids in the proper ratios to help ensure growth and development. Soy also contains a number of other needed nutrients. These include the full B-complex vitamins, potassium, Vitamin E, iron and zinc. Soy proteins are high in Arginine and glutamine; these are two amino acids that are essential to the muscles. Arginine helps to stimulate muscle growth and formation and the glutamine is needed during times of metabolic stress. Whey proteins are high in branched chain amino acids, which are needed for energy while you are exercising. From this vantage point it would seem that using the two proteins together would be advantageous to building muscle and supporting the body during exercise. Contrary to popular belief among men in the body building industry, soy proteins have not been shown to decrease testosterone levels and cause a feminization of the body making it more difficult to build muscle. Numerous studies have actually not only shown the soy protein is as effective as whey protein but that it may even be better for not only building muscle but retaining it. The American College of Sports Medicine published a study in 2004 that showed that after a workout those that consumed is nitrogenous and isoenergetic soy drinks had a dramatic impact on muscle strength and fat-bone free mass. The soy protein stopped the two negative effects that bodybuilding has on the muscles and supported muscle hypertrophy. Where does this leave the soy protein vs whey protein battle? Both soy protein and whey protein are equally effective in building lean muscle mass. The soy protein however offers the muscles support after the workout and helps you maintain your muscle mass. Soy proteins also offer you the perfect ratio of all the amino acids your body needs for growth and development.
