Precautions:

For people with poor gastrointestinal digestive function, sweet potatoes and eggs are not easy to digest, and it is even more difficult to digest when eaten together, which is easy to cause abdominal distension and abdominal pain. So sweet potatoes can't be eaten with eggs.

Persimmons should not be eaten for a short time after eating sweet potatoes. If eaten together, the sugar in sweet potato will ferment in the stomach and produce too much gastric acid. Tannin and pectin in persimmon will coagulate with substances in sweet potato, resulting in abdominal mass, which will also lead to gastric bleeding and gastric ulcer in severe cases.
