1, milk contains high calcium, which is the main source of calcium supplement. There is no doubt that milk and dairy products are the best sources of dietary calcium. The calcium content in fresh milk can reach 1000- 1200mg per liter, and skim milk powder is higher.

2. Soybeans and bean products are also good sources of calcium. The content of calcium in tofu is110-140mg;

3. Green leafy vegetables, especially dark green leafy vegetables and cauliflower, also contain high calcium content, with calcium content of 50-130 mg per 100g; Although spinach and water spinach contain high calcium content, they contain a lot of oxalic acid, and the absorption rate of calcium in human body is relatively low; The calcium content of beans and fresh beans is 30mg per 100g, while the calcium content of other vegetables is relatively low.

4. Fruits like citrus have a relatively high calcium content, basically containing 20-30mg of calcium per 100g, while other fruits have a relatively low calcium content;

5. Among animal foods, the calcium content of shellfish is relatively high, reaching 200mg per 100g. The calcium content of fish is also relatively high, such as eggs, livestock and poultry, which are relatively low, and generally the calcium content per 100g is less than 15mg. Like sesame and small fish, the calcium content is also relatively high, but because the daily consumption like shrimp skin is limited, the contribution rate to dietary calcium is relatively small, so it is more difficult to supplement calcium by food like shrimp skin or sesame. Therefore, in the daily diet, milk is very important and key, and it is a more important source of calcium intake. Hope to adopt thank you.
