1. Dairy Products: Dairy products are a cost-effective source of calcium, with milk containing up to 110mg of calcium per 100g. It is easily absorbed by the body.
2. Soy Products: Soy products like tofu, dried tofu, and tofu skin are also good sources of calcium. A 350g box of tofu contains about 400mg of calcium, although the absorption rate is lower than dairy products.
3. Dark Green Vegetables: Some dark green vegetables have calcium levels comparable to or higher than milk, such as shepherd's purse, amaranth, mustard greens, edamame, and broccoli.
