First, eat more vegetables. Vegetables not only contain a lot of potassium and magnesium, but also help to maintain acid balance and reduce calcium loss.

Second, milk has a good calcium supplement effect. Milk contains a lot of protein and is rich in potassium and magnesium, which can promote the absorption of calcium. Milk will not only make people's body fluids sour, but also will not promote the loss of calcium, so milk is the best food for calcium supplementation.

Third, eat more soy products, such as soybeans, which are high-protein foods with high calcium content.

Fourth, eat more animal bones, which contain more than 80% calcium. Fifth, the shortcut to calcium supplement is to eat less salt.
