Chestnuts are warm, fried and eaten more warmly, and it is easy to get angry if you eat too much. Chestnuts can tonify spleen and stomach, tonify kidney and strengthen tendons, and promote blood circulation to stop bleeding. It has a good curative effect on kidney deficiency, so it is also called "the fruit of kidney".

But chestnuts are hard to digest when eaten raw, and cooked food is easy to lag behind. Eating too much at a time will hurt the spleen and stomach, and eat at most 10 chestnuts a day.

Others like to stew things with chestnuts, mostly meat. Because stewing will increase the sugar and fat content in chestnut, it is easier to get angry if you eat too much. Moreover, eating chestnut is easy to cause flatulence and difficult to digest.
