Chestnut Hao health

"Purple, red and wrinkled dates are always sweet, but easy chestnuts are always lost", which is a poem by Fan Chengda, an idyllic poet in the Song Dynasty, praising chestnuts. Chestnut, commonly known as Castanea mollissima and Castanea mollissima, is the fruit of Castanea mollissima of Fagaceae. It is not only rich in nutrition, but also has good dietotherapy and health care functions. It is the favorite health care fruit in mid-autumn and is known as the "king of dried fruits". Chestnut has a long history of cultivation in China. In the ancient book The Book of Songs, there are records of "hazel chestnut in the tree" and "chestnut in the east gate". "Lu's Spring and Autumn Annals" also has the saying that "those who are beautiful in fruit have chestnuts in Mount Ji". Chestnuts are also found in the Neolithic relics unearthed in Banpo, Shaanxi Province, indicating that chestnuts were eaten by people more than 5,000 years ago. In the Warring States Policy, there is a record that "there are benefits of jujube chestnuts in the north, although the people do not farm, jujube chestnuts are enough to eat". There are many varieties of chestnut in China, but they can be roughly divided into two groups: the chestnut in the north of the Yellow River has smaller particles, low starch content and fine and waxy texture, which is suitable for frying chestnut; Chestnut produced in the south of the Yellow River has large fruit, high starch content, thick and sticky quality, and is suitable for vegetable use. According to the determination, every100g of fresh chestnut contains 53g of water, 4g of protein, 39.9g of carbohydrate, 0/86kcal of calories/kloc-0, 5mg of calcium/kloc-0, 60mg of vitamin C and carrots. Chestnut is sweet and crisp when eaten raw, but it is pink and fragrant when cooked, which has a unique flavor.
