Bones, dairy products, beans, shrimp skin, fish, soybeans, melon seeds (sunflower seeds and pumpkin seeds), grains (especially rye, millet and barley), kelp and nuts.

Maintain the normal excitement of muscles and nerves. For example, the increase of blood calcium can inhibit the excitability of muscles and nerves; When the blood calcium is lower than 70mg/L, the excitability of neuromuscular increases and convulsions occur. Irritable bowel syndrome, dysmenorrhea in girls and calcium deficiency are important reasons.

2: containing phosphorus

Soybeans, string beans, tofu coat, mushrooms, laver, fried watermelon seeds, fried pumpkin seeds, skimmed milk powder, egg yolk, sharks, sharks, dried whitebait, scallops, dried squid, shrimps, dried shrimps, river crabs and sesame paste.

Both phosphorus and calcium are important components of bones and teeth, and they are indispensable nutrients to promote calcification of bones and teeth. Some babies often suffer from rickets or rickets because of lack of calcium and phosphorus. The main component of bones and teeth is called apatite, which is composed of phosphorus and calcium.

3: containing iron

Apricot, spinach, cherry, jujube, fish, kelp, milk, eggs, laver, soybean, celery, rape, tomato, orange, sesame paste, auricularia auricula, bean products, animal liver, animal whole blood, and livestock meat.

4: Does it contain iodine?

Kelp, laver, jellyfish, clam, shrimp skin, squid, mussel, sea cucumber, marine fish, shrimp, dried clam, spinach, Chinese cabbage and corn.

Adults contain 20-50 mg of iodine, which is an essential element to maintain the normal function of human thyroid. If the human body lacks iodine, it will suffer from goiter. Therefore, iodide can prevent and treat goiter. Eating more iodine-rich foods such as kelp and marine fish is also effective in preventing and treating goiter. Radioisotope I of iodine can be used for early diagnosis and treatment of thyroid tumors.

5: containing zinc

Oyster, animal liver, peanuts, fish, eggs, milk, meat, fruit, pig liver, pig kidney and lean meat; Fish, seaweed, oysters and clams in seafood.

Zinc is a nutrient for thymus development of immune organs. Only sufficient zinc can effectively ensure the development of thymus, differentiate T lymphocytes normally and promote cellular immune function.

Zinc contributes to growth and development, intellectual development and improving immunity. Zinc deficiency will seriously affect our health, especially our growth and development. Therefore, it is necessary to supplement enough zinc to promote growth and intellectual development. In addition to a balanced diet, don't forget to supplement nutrition properly.

Extended data:

First of all, shrimp skin

Shrimp skin is actually mainly made of a kind of shrimp called hairy shrimp. Shrimp skin has high nutritional value. As far as the protein content used to measure the nutritional value is concerned, every 100g shrimp skin contains 39.3g of protein, which is much higher than aquatic products such as Pseudosciaena crocea, yellow croaker, prawn, hairtail and pomfret, and meat products such as beef, pork and chicken.

Second, soybeans.

Soybean fat also has high nutritional value, contains a lot of unsaturated fatty acids, and is easily digested and absorbed by human body. Moreover, soybean fat can prevent the absorption of cholesterol, so soybean is an ideal nutrient for patients with arteriosclerosis.

Third, kelp.

Kelp is rich in laminarin, mainly fucoidan, fucoidan and fucoidan. It also contains acidic polysaccharide, fucoidan, fucoidan, galacturonic acid, laminin, taurine, bifidus factor and other active ingredients.

Kelp is a kind of nutritious edible brown algae, which contains more than 60 kinds of nutrients, mainly including protein, fatty carotene, nicotinic acid, calcium, iron and phosphorus, and is also rich in alginic acid, cellulose, mannitol and various trace elements.

Fourth, spinach.

Spinach is known as a "nutrition model student", which is rich in carotenoids, vitamin C, vitamin K, minerals (calcium, iron, etc. ), coenzyme Q 10 and other nutrients.

Verb (abbreviation for verb) oyster

Oyster meat contains a lot of glycogen, which is the energy of cell metabolism. Supplementing glycogen can improve heart function and blood circulation, enhance liver function and protect liver. Glycogen in oysters can also be directly absorbed and utilized by the body, thus reducing the burden on the pancreas, so it is very beneficial to diabetes.
