Tip - 1/2 a cup of soya beans contain all the 9 amino acids

Soybeans are the only vegetables that are a complete protein, meaning it contains all nine of the essential amino acids--amino acids that our bodies can not make and must be obtained from food. In fact, soybeans produce more than two times as much protein per acre of land than any other crop of vegetable or grain. Soybeans are used in a multitude of foods, including soy milk, tofu, tempeh (fermented soybeans), soy cheese, soy yogurt, soy nuts, edamame (green, immature soybeans), mature yellow soybeans, miso (a thick paste made from fermented soybeans and barley or rice malt--used in Japanese cooking to make soups or sauces), textured vegetable protein ('TVP'--used as a meat alternative), and others. The protein content of soy foods varies, ranging from about 25 grams for a ½-cup serving of TVP to 4 grams for a 2 Tbsp serving of miso paste.
