Eating hot sugar-fried chestnuts in winter is the warmest memory of many people when they were young, and because of its sweet and soft taste, it has become one of the first choice for new year's goods during the Spring Festival.

Chinese medicine believes that chestnut is sweet and warm; Entering the channels of kidney, spleen and stomach, it has the effects of nourishing stomach, strengthening spleen, benefiting qi, tonifying kidney, strengthening waist, strengthening tendons, stopping bleeding, reducing swelling and strengthening heart.

"Compendium of Materia Medica" records that "treating kidney deficiency, waist and foot weakness, hanging chestnuts in bags, eating more than ten chestnuts a day, and eating pig kidney porridge to help them, will be strong for a long time." So people with kidney deficiency may wish to eat more chestnuts.

Expert comment: There are many ways to eat chestnuts. In the south, chestnuts are used for cooking, which is a kind of banquet food. Chestnut black-bone chicken and chestnut braised mutton are household names.

Chestnuts fried with sugar in the north are waxy, fragrant, sweet and delicious. Grinding chestnut meat and cooking porridge with japonica rice can not only strengthen the spleen and stomach, but also stimulate appetite, which is especially suitable for the elderly with loss of appetite and weak waist and knees caused by functional degradation.

However, it should be noted that if you tonify the kidney, the effect of raw chestnut may be better than that of cooked chestnut, and it is appropriate to eat 1~2 capsules every morning and evening.
