Trusted as a dietary staple in Asia for centuries, the soybean is a unique natural source of high-quality nutrition. In fact, soy is the only commonly consumed plant-based protein that is nutritionally complete, containing all of the essential amino acids required for optimum health.
In addition to complete protein, soybeans also provide fiber, iron, and naturally occurring ALA omega-3 fatty acids. They are low in saturated fat and, like all plant foods, cholesterol-free.
In order to reap maximum benefit from soy in the diet, consumers should select minimally processed soyfoods that preserve as much of the soy plant’s inherent nutrition as possible. Tofu, tempeh, edamame, and soymilk made from whole soybeans are all good choices.
Although soy supplements may offer specific support for particular conditions,1 it is important to note that for overall nutrition, soy supplements and foods made from isolated soy protein may not offer the same well-rounded balance of nutrients as foods made from whole soy.
