In addition, fish, shrimp, nuts and other foods all contain more calcium, which is beneficial to the prevention of osteoporosis. People who already suffer from osteoporosis, hypocalcemia and other diseases need to supplement calcium through other ways, and at the same time cooperate with diet therapy to relieve calcium deficiency symptoms:

4. Nuts: hazelnuts, almonds, walnuts, chestnuts, peanuts and other nuts also contain more calcium, and moderate consumption is also conducive to calcium supplementation;

5. Others: spinach, celery, cabbage, mustard, mushrooms, fungus, radish, seaweed, kelp and other vegetables, as well as apples, bananas, grapefruit, figs and other fruits also contain more calcium, which can also be eaten in moderation, but the digestion and absorption rate is low, so it is generally not used as the main food source of calcium.

The absorption of calcium also needs the participation of vitamin D, so when ingesting calcium-containing foods, it is generally necessary to eat foods rich in vitamin D at the same time, such as egg yolk, animal liver, etc., or to enhance the absorption of calcium through sunlight.
