Chestnuts themselves are rich in nutritional value, and chestnuts fried with sugar in a large iron pot are softer and more delicious. The heat of 100g chestnut is about 2 14kcal, while that of 1 16kcal rice is 165438, which means there are 100g small-shell chestnuts or six large-shell chestnuts, so the heat of chestnuts is not low.
