Tofu is low in calories, contains beneficial amounts of iron (especially important for women of child-bearing age) and has no saturated fat or cholesterol. Depending on the coagulant used in manufacturing, the tofu may also be high in calcium (important for bone development and maintenance), and magnesium (especially important for athletes). Tofu also contains soy isoflavones, which can mimic natural human estrogens and may have a variety of harmful or beneficial effects when eaten in sufficient quantities.
