Is tofu a good source of calcium?
Many kinds of tofu are excellent sources of calcium, but not all. If tofu is processed with calcium sulfate — as most are — it will have about 260mg of calcium per cup. This calcium is as absorbable by the body as the calcium in milk. But tofu processed with nigiri will have little calcium. Similarly, calcium-fortified soy milk contains 300mg of calcium, the same as a cup of milk, but not all soy milks are fortified. Read the label to be sure.
