“Soy may be similar to unprocessed forms of most other foods in that they are a bit healthier and may impart more clear health benefits than their processed counterpart,” Hendel said. ”Soy is a complete protein and therefore is an excellent way to get the vitamins, calcium, iron and phytonutrients that soy offers.” Hendel recommends that people consume two to three servings of soy food products each day, or around 25 grams of unprocessed soy.
