Soy foods

Calcium is rich in soybeans by nature. Edamame beans are young soybeans that are often sold in their pods. Cooked edamame contains 8% of the daily value for calcium in one cup (155 grams). It's also high in protein and has all of your daily folate requirements in a single serving. Tofu made with calcium also contains a lot of it, with almost 66% of the daily value for calcium in only half a cup (126 grams).

Soybean-based foods like tofu, tempeh, and natto are also high in this mineral. The amount of calcium phosphate in 3.5 ounces of tofu is 350 mg (100 grams). Tempeh and natto, both produced from fermented soybeans, are other good sources. One 3.5-ounce (100-gram) serving of tempeh provides around 11% of the RDI, whereas natto provides almost twice as much.
