Autumn and winter have arrived, and sweet potato chestnuts are popular in the market again. Most people think that sweet potato is low in calories and full, and it is a good food whether it is a staple food or a non-staple food.

I think so too. Every night when I come home from work, I will buy a baked sweet potato on the way. Sweet and warm, it not only fills my stomach, but also reduces the chill that gradually turns cold. The best of both worlds!

But last week, Uncle Liu ate a few sweet potatoes for dinner next door, and ate a persimmon less than half an hour later. When I watched TV at night, my stomach ached badly and I had to go to the hospital.

I'm surprised. Later, I asked Uncle Liu's son. What happened? Uncle Liu's son said: Alas, the doctor said that my father has diabetes, and eating sweet potatoes, especially persimmons, is simply adding fuel to the fire.

When I came back to check the information, I knew that chestnuts and sweet potatoes are rich in nutrition, but they have high starch content and will become glucose after digestion.

For diabetic patients who lack insulin and can't regulate blood sugar normally, it is not advisable to eat 50 grams of sweet potatoes or more than 5 chestnuts at a time. Eat less bread and other foods after dinner that day.

In addition, because excessive potassium will increase the burden on the kidneys and make patients with kidney disease feel more uncomfortable, it is best to eat less chestnuts and sweet potatoes.
