Peanut contains 40% ~ 50% fat, twice as much as soybean and higher than rapeseed. 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 longevity effects of peanuts are as follows: first, eating peanuts can decompose cholesterol in human liver into bile acids, which can enhance its excretion and thus reduce cholesterol. Second, peanut coat 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.

As a perfect match for peanuts, vinegar can not only make vegetables tender and sweet, but also stimulate appetite, promote digestion and sterilize, especially for salty and greasy foods, adding vinegar can reduce the salty taste and greasy feeling. The "fairy match" between vinegar and peanuts is scientific, because the value of peanuts lies in containing unsaturated fatty acids needed by the human body, but after all, it is high in fat, high in calories and greasy. All kinds of organic acids in vinegar are 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, which can be described as the best of both worlds! However, it should be noted that it is necessary to eat in moderation, up to a dozen capsules, and rinse your mouth in time after eating, otherwise it will be bad for your teeth. Both cooked and raw peanuts are acceptable (it is better to eat raw peanuts with skin, which is better)
