Peanut, formerly known as groundnut (scientific name: Arachis hypogaea Linn.), is a kind of nut with abundant yield and wide consumption in China, also known as "longevity fruit" and "mudou". It belongs to Rosaceae, panicum miliaceum, Leguminosae, with erect or creeping stems, 30-80 cm long, wings separated from keel, pods 2-5 cm long, 1- 1.3 cm wide, swollen, thick pods, and flowering and fruiting in June-August. Mainly distributed in Brazil, China, Egypt and other places. It can be used as raw material for cosmetics such as soap and hair tonic.

Peanut fruit contains protein, fat, sugar, vitamin A, vitamin B6, vitamin E, vitamin K, and minerals such as calcium, phosphorus and iron. It contains eight kinds of amino acids and unsaturated fatty acids needed by human body, including lecithin, choline, carotene and crude fiber.

The fat content is 44%-45%, the protein content is 24-36% and the sugar content is about 20%. It is rich in vitamins B2, PP, A, D, E, calcium and iron. It also contains thiamine, riboflavin, niacin and other vitamins. It can promote the development of human brain cells and enhance memory.

Extended data:

When the soluble fiber in peanut fiber tissue is digested and absorbed by the human body, it will absorb liquid and other substances like a sponge, and then expand into a tape body to be excreted with feces. When these objects pass through the intestine, they come into contact with many harmful substances and absorb some toxins, thus reducing the accumulation of harmful substances in the body and the toxic effects, and reducing the chance of intestinal cancer.
