It is a healthy food suitable for all ages.
In terms of nutritional value, since the amino acid composition of SPI is similar to animal protein, it can replace animal protein. Moreover, soybean protein has irreplaceable advantages of animal protein. Not only does it not contain cholesterol, but its unique physiologically active substance isoflavones also has the effect of lowering cholesterol. It is also known as the most nutritious plant protein.
