Soy protein isolate benefits on muscle building

If you are on a diet but do not want to compromise your need for protein, you can add soy protein to your diet. It is an excellent substitute for animal protein. It has no cholesterol and contains saturated fat in small quantities. It is also a good source of vitamin B12, iron, calcium, zinc, and fiber. Even more, soy protein isolate benefits on muscle growth are huge, therefore soy protein isolate is essential for bodybuilders, along with whey protein and BCAA (branched chain amino acids).


Varieties of soy protein

Soy protein is present in various preparations, such as soy soup, meat imitations, cheese, milk and soy cream, milk formulas for infants, cereals, pasta, and bread. It can be divided into categories, depending on how it is produced.

The most refined form is called soy protein isolate. It is used in the production of meat substitutes, because it improves the texture and quality.

Soy Protein Isolate has about 90% protein.

Soybean protein concentrate, on the other hand, is found in soybeans in which carbohydrates have been eliminated. Soy protein concentrates contains 70% of soy protein.

Soy proteins is a complete protein

Soy protein contains all the essential amino acids of nutrition, earning the name of complete protein.

For example, cereals contain very small amounts of lysine, while legumes and vegetables have a low content of methionine and cysteine, two amino acids containing sulfur.

The soy protein contains these amino acids in large quantities, reaching a level similar to that of the animal protein, which makes soy protein essential for weight loss diets, vegans and vegetarians.

Legumes and vegetables have proteins with around 30% of the calories intake. The value is higher in the soybean protein. About 38% of soybean calories are attributed to their protein content.

Besides these obvious advantages of soy protein, it is also among the cheapest sources of protein in a diet. So when you keep a diet, using soy protein can provide you with the complete protein requirements without leaving a hole in your budget.


Soy protein is of high quality

Besides being a complete protein, soy is a high quality protein.

Soy has enough essential amino acids to meet the requirements for children between the ages of 2 and 5 years, being the group of years in which the maximum protein requirement should be met.

In addition, the soy protein is digested easily, reaching a digestibility score of about 97%.

The regular soy protein helps to reduce total cholesterol, and helps lower the levels of low-density lipoprotein (low cholesterol) and triglycerides. To get these benefits, eat at least 25g of soy protein every day. This quantity is about 1¼ cup of tofu, 30ml of soy flour or one-two cups of soy milk.

Obesity, diabetes, cancer, and menopause seem to be also reduced by the regular intake of soy protein. With regard to obesity and diabetes, consumption of soy protein can control hyperglycemia and hyperinsulinism, and can help maintain a healthy weight.

It has been shown that a chemical called genistein, which is present in soy, reduces the risk of breast cancer.

Phytoestrogens, which are also compounds of estrogen, are present in soy proteins. Regular intake of soy protein may help avoid the effects of menopause, including bone loss and increased cardiovascular risk.


Soy protein isolate benefits on muscle building

Soy protein isolate has properties that support the most effective protein supplement for growing the muscle mass, containing 90% soy protein plus amino acids, vitamins and minerals (all essential for muscle growth).

Besides, soy protein isolate contains protein isolate from soybeans, which are the vegetable proteins with the highest purity level.

The complete and efficient concentrated profile of soy protein isolate amino acids creates the environment for anabolism, leading to the development of muscle tissues.

Additionally, it ensures the needed vitamin and mineral supplementation for healthy growth (through the added protein mix), supporting metabolic processes by increasing muscle mass by the carnitine infusion (for an excess of fat)

Moreover, soy protein isolate offers the best anti-catabolic response, providing proteins that creates the proper hormonal environment and energy-efficient efficacy to prevent muscle tissue damage after training.

Soy protein isolate benefits on muscle building are given by the intrinsic quality of soy protein and the concentration that is specific to the isolate - 90% protein. Additionally, consuming soy protein brings other benefits to overall health including lower cholesterol, lower risk for developing cancer, reduced symptoms in women at menopause, and it also help diabetics to keep their glucose level under control.
