My left leg cramps when I run and I often have stomachaches

Running is a sport that many people like. By running, you can strengthen your body. However, some people may experience leg cramps and stomach pain when running. This symptom is caused by calcium deficiency, so calcium supplementation is needed in time. So, what foods can supplement calcium in daily life? Below, I will introduce in detail several foods that can supplement calcium.

1. Sesame paste

Sesame paste is rich in protein, amino acids, and various vitamins and minerals, and has high health value; the calcium content in sesame paste is much higher than that in vegetables and beans, and regular consumption is beneficial to the development of bones and teeth (do not eat it with vegetables such as spinach, otherwise it will undergo a double decomposition reaction with oxalic acid or soluble oxalate in the vegetables to form calcium oxalate precipitate, affecting calcium absorption). The iron content of sesame paste is several times higher than that of pork liver and egg yolk. Regular consumption not only has a positive effect on adjusting partial eclipse and anorexia, but also can correct and prevent iron deficiency anemia.

2. Shrimp

Shrimp skin is rich in calcium. 100 grams of shrimp skin contains 991 mg of calcium, second only to sesame paste. Shrimp is rich in nutrients, containing several to dozens of times more protein than fish, eggs, and milk. It is also rich in minerals such as potassium, iodine, magnesium, phosphorus, and vitamin A, aminophylline and other ingredients. Its meat is soft and easy to digest, making it an excellent food for people who are weak or need recuperation after illness.

3. Milk

Milk is very nutritious and contains a wide variety of minerals. In addition to the calcium we are all familiar with, it also contains a lot of phosphorus, iron, zinc, copper, manganese and molybdenum. The most valuable thing is that milk is the best source of calcium for the human body, and the calcium-phosphorus ratio is very appropriate, which is conducive to calcium absorption. The types are complex, with at least 100 kinds, and the main components are water, fat, phospholipids, protein, lactose, inorganic salts, etc.

4. Black Fungus
