When selecting yam in the market, it is best to choose yam with white color, no pests and diseases, and yam with long sticky line and tender meat after cutting. If you choose: 1 by variety, the iron stick yam in Henan is the best (the price is too expensive). Besides, white mouth (purple medicine) is also delicious (at a moderate price). There are too many kinds of great drugs, so I won't say them one by one.

Sweet potato is called "soft gold"

Yam: It is warm and sweet, non-toxic, and has the functions of invigorating the middle energizer, strengthening the spleen and stomach, promoting granulation, stopping diarrhea, strengthening the kidney, solidifying essence and benefiting the lung.

Suitable for weakness, mental fatigue, loss of appetite, dyspepsia, chronic diarrhea, cough, nocturnal emission, night sweats, diabetes and nocturia. Yam is rich in nutrition, containing protein, arginine, vitamins, sugars, minerals, mucus, starch and other substances. Amylase decomposes starch, so it does not stagnate.

Therefore, eating some yam every day is good for your health. Especially after cooking, the taste is soft, which is beneficial to chewing and absorption, and is more suitable for people with bad teeth like the elderly and children.

(Mashu not only clears the lungs but also helps digestion.)

In addition, it is precisely because of its low calorie and no sucrose that it has become an ideal food for diabetic patients.
