Getting the daily requirement of zinc from vegetarian diets is challenging. Phytic acid, which is found in various foods, such as legumes and seeds, inhibits zinc absorption. Studies indicate that women who consume a vegetarian diet need approximately 25 percent more zinc than their omnivorous counterparts. Tofu, coagulated soy protein, is one of the best sources. The process of making tofu, which involves stages of soaking and heating, reduces phytates, and makes zinc more bioavailable.
