Sweet potatoes will not produce harmful components like potatoes after germination. As long as the long buds on the sweet potato are removed, they can be eaten, and there will be no legendary poisoning symptoms. However, it should be noted that sweet potato not only tastes bad after germination, but also loses its edible value because of a large loss of nutrition and water.

As for the statement that eating germinated sweet potatoes will cause poisoning, it is groundless, unscientific and purely a misunderstanding of life. Nutritionists believe that sweet potato is not only a nutritious food, but also a good dietotherapy for many diseases. Eating sweet potatoes has many benefits, but we must pay attention to scientific methods.

Although the germinated sweet potato can be eaten, if the skin is brown or black spots, it can't be eaten because it is polluted by black spot bacteria. The toxin released by Alternaria alternata contains sweet potato ketone and sweet potato ketone alcohol, which makes sweet potato hard and bitter and highly toxic to human liver. Although this toxin is boiled and baked, its biological activity will not be destroyed. After eating, it usually occurs within 24 hours, with gastrointestinal symptoms such as nausea, vomiting and diarrhea. Severe cases also have high fever, headache, asthma, confusion, vomiting, coma and even death.

What should I pay attention to when eating sweet potatoes?

1, it is good to eat sweet potatoes at lunch time.

This is because after we eat sweet potatoes, the calcium contained in them needs to be absorbed in the human body for 4 to 5 hours, and the afternoon sunshine can just promote the absorption of calcium. But it is good to eat sweet potatoes before lunch, so that calcium can be completely absorbed before lunch, and it will not affect the absorption of calcium in other foods at dinner.

2. When the sweet potato is processed, it must be steamed and cooked thoroughly.

This will destroy the cell membrane of starch because it is difficult to digest. In addition, if the gasification enzyme in sweet potato is not destroyed by high temperature, we will feel uncomfortable after taking it.
