Chinese medicine believes that chestnuts are sweet and warm, and have the effects of nourishing stomach and strengthening spleen, tonifying kidney and strengthening tendons, promoting blood circulation and stopping bleeding, relieving cough and resolving phlegm, and are especially suitable for people with weak waist and knees, paralysis of waist and legs, frequent urination, spleen deficiency and fear of cold. Modern research believes that chestnut is a kind of dried fruit with high carbohydrate content, which can provide more heat energy and help the body resist the cold, so it is more suitable for autumn and winter.
Chestnut contains unsaturated fatty acids, vitamins and minerals, which has a good preventive and therapeutic effect on diseases such as hypertension, coronary heart disease, arteriosclerosis and osteoporosis. Therefore, the elderly often eat chestnuts, which can achieve the purpose of prolonging life. In addition, chestnuts are rich in riboflavin, which can be eaten frequently by friends who are troubled by oral ulcers.
Chestnuts can not only be cooked, but also eaten raw, and eating raw chestnuts has a better effect of tonifying kidney. As early as the Tang Dynasty, Sun Simiao, a medical scientist, called chestnut "the fruit of kidney", pointed out that eating it raw could cure lumbago and leg pain, and emphasized its usage. If middle-aged and elderly people develop the habit of eating air-dried raw chestnuts every day, they can effectively prevent kidney deficiency, backache and leg pain.
Although chestnuts can tonify the kidney, too much raw food can also cause indigestion, and too much cooked food can cause gastrointestinal obstruction. So the daily consumption of chestnuts is about 5- 10.
Remind diabetics again that chestnuts are not edible. Chestnuts are high in sugar, so it is best to eat them in moderation.
