Peanut contains 40%-50% fat, twice as much as soybean and higher than rapeseed. It contains about 30% of 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 fruits". The longevity effects of peanuts are as follows: First, eating peanuts can decompose cholesterol in human liver into bile acids, so that its excretion is enhanced, thus lowering cholesterol. Second, peanut skin 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 the "perfect match" of peanuts, vinegar can not only make vegetables fresh, sweet and fragrant, but also have the effects of stimulating appetite, promoting digestion and sterilization, especially for salty and greasy foods, adding vinegar can reduce salty taste and greasy feeling. The "fairy match" between vinegar and peanuts is scientific, because the value of peanuts lies in the fact that they contain unsaturated fatty acids needed by the human body, but after all, they are high in lipid content, high in calories and greasy. The various organic acids in vinegar are just greasy and fragrant, so soaking peanuts in vinegar 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 you should eat in moderation and rinse your mouth in time after eating, otherwise it will be bad for your teeth. Cooked and raw peanuts can be used (it is best to eat raw peanuts with skin, which is better). It seems so.
