Benefits of Soya

An Overview

     Soybean is hailed as the most protective bean. Soy contains 26 percent protein. It has the highest protein content amongst plant products. “Soy protein” refers to the protein found in soybeans. They are an important component of Asian diets and have been consumed for thousands of years. Today, they are mainly grown in Asia and South and North America. As animal protein contains all the essential amino acids, lacking in pulse protein, soy is often used to replace the animal proteins in an individual’s diet. Various soy products are available, including soy flour, soy protein, tofu, soy milk, soy sauce and soybean oil.

     Soybean is the richest plant source of protein. Soy protein is also of the highest quality amongst all legumes. The World Health Organization (WHO) and the US Food and Drug Administration use an alternative method for evaluating protein quality called the Protein Digestibility Corrected Amino Acid Score (PDCAAS). Soybeans are among the best sources of plant based protein. The protein content of soybeans is 36–56% of the dry weight. Soy foods if used smartly contribute significantly toward meeting protein needs, and could be an excellent addition to a diet for a variety of reasons.
