Positive properties of soy
Soy is an important food in the diet of vegetarians because it is a rich source of protein.
Not only that.
Soy proteins are a highly desirable addition to any method of food.
They have a beneficial effect on the human body.
Soy protein can be a great substitute for proteins that are found in meat.
The advantage of this ingredient in relation to the meat lies in the fact that its proteins are not associated with fat.
Soy proteins are not only of plant origin but are classified into high-quality protein.
That is because it has almost all amino acids, found in meat.
They are useful for developing and maintaining healthy and solid muscle mass.
Amino acids from this product are also involved in the production of insulin in the body, which is very important for diabetics.
