Purple potato has high nutritional value, but when eating it, we should pay attention to:

1, purple sweet potato contains more carbohydrates, and it is best not to exceed 200 grams at a time.

2. Purple sweet potato should not be eaten on an empty stomach, and it is easy to feel heartburn. It is recommended to eat with foods rich in fat and protein, such as eggs, or with other vegetables.

3. The germinated purple potato is poisonous. When purple sweet potato germinates, starch and sugar will be degraded into nutrients needed for germination. Purple potato will release some toxins in the process of degradation, which will make purple potato easy to mildew and rot (due to the increase of starch decomposition, it is easy to deteriorate).
