2. Bean products. Soybean is a high-protein food with high calcium content. 500 grams of soybean milk contains calcium 120 mg, and 150 grams of tofu contains calcium as high as 500 mg. Other bean products are also good products for calcium supplementation. In addition, experts from Changchun Orthopedic Hospital remind you that soybean milk needs to be boiled for 7 times before it can be eaten. Tofu, on the other hand, should not be eaten with some vegetables, such as spinach. Spinach contains oxalic acid, which can combine with calcium to form calcium oxalate conjugate, thus hindering the absorption of calcium by human body, so tofu and other bean products are not suitable for cooking with spinach. However, if bean products are cooked with meat, they will be delicious and nutritious.
3. kelp and shrimp skin. Kelp and shrimp skin are high-calcium seafood. If you eat 25 grams a day, you can supplement 300 milligrams of calcium. And they can also reduce blood lipids and prevent arteriosclerosis.
Kelp cooked with meat or cooked in cold sauce is a good food. Shrimp skin contains more calcium, and 25 grams of shrimp skin contains 500 mg of calcium. Therefore, it is a good choice to make soup or stuffing with shrimp skin.
4. Animal bones. More than 80% of animal bones are calcium, but it is insoluble in water and difficult to absorb, so it can be broken in advance when it is made into food, and then cooked slowly with vinegar. When eating, remove the oil slick and add some vegetables to make a delicious soup.
Friendly reminder: fishbone can also supplement calcium, but we should pay attention to choosing the right method. Dry fried fish and braised crispy fish can make fish bones soft, which is more convenient for calcium absorption and can be eaten directly.
