Peanut has a high nutritional value, containing 40%-50% fat, which is twice that of soybean. It contains about 30% protein, which is more than twice that of wheat and three times that of rice. Moreover, peanuts are easily absorbed by the human body, and the digestion coefficient is about 90%. In addition, peanuts also contain riboflavin, calcium, phosphorus, lecithin, choline, unsaturated fatty acids and various vitamins, so peanuts are also called "longevity fruit".

The health care functions of peanuts are as follows: 1. Eating peanuts can decompose cholesterol in human liver into bile acids, so that its excretion is enhanced, thus lowering cholesterol. Second, the red coat of peanut kernel (the skin of peanut kernel) can inhibit the dissolution of fibrin, promote platelet regeneration and strengthen the contraction function of capillaries, which is beneficial to patients with thrombocytopenia, pulmonary tuberculosis hemoptysis and urinary tract bleeding.

To give full play to the health care function of peanuts, we should pay attention to scientific eating methods:

Peanuts should not be eaten raw: peanuts contain more fat and are slowly digested and absorbed by the human body. Eating a lot of peanuts raw can lead to indigestion. In addition, peanuts grow in the soil and are often polluted by parasitic eggs, which can easily cause parasitic diseases if eaten raw. At the same time, peanuts are often polluted by rodents, which is easy to spread natural focus diseases, especially epidemic hemorrhagic fever. Therefore, peanuts should not be eaten raw, and it is best to cook them before eating.

Boiled peanuts have high nutrition: some people are used to eating fried peanuts or eating them after frying, which will destroy a large number of glycerides and ethylene glycol esters contained in peanut red clothes, so boiled peanuts and red clothes have higher nutritional value. In addition, peanuts are susceptible to aflatoxin. Aflatoxin contaminated by peanuts can be basically dissolved in water after being boiled, so it is safer to eat.

Peanut soaked in vinegar "immortal match": Peanut contains unsaturated fatty acids needed by human body, but after all, it has high fat content, high calorie and greasy feeling. However, many organic acids in vinegar are just greasy and fragrant. Therefore, soaking peanuts in vinegar for more than a week and eating 7- 10 capsules every night for a week can lower blood pressure, soften blood vessels and reduce the accumulation of cholesterol.

Eating more peanuts is harmful to your health: peanuts are rich in oil and are not easy to digest. Too much peanuts can't be digested, resulting in direct excretion of peanuts. Those with cold, dampness, stagnation and diarrhea should take it according to the doctor's advice;

Avoid eating moldy peanuts. In the experiment of eating moldy edible animals, it was found that the consumption of moldy peanuts was the smallest and liver cancer was the fastest.

Peanuts that are not obviously mildewed are generally ignored, but the risk of disease is not small.

It should be used in a timely and appropriate manner, and the dosage should be reduced in hot summer. Make it beneficial and harmless.
