Sprouted potatoes are not recommended for consumption, especially those with large sprouted areas. Sprouted potatoes have a high content of toxic substances. Potatoes contain natural toxicity, i.e. the component of lobelia alkaloids, which is a poisonous substance that is highly irritating and corrosive to the gastric mucosa. Fresh potatoes contain trace amounts of lobelia alkaloids, which do not have harmful effects on the human body. However, sprouted potatoes have a higher content of anemone alkaloids, after treatment can still not completely eliminate its toxicity, consumption can cause poisoning, nausea, vomiting, diarrhea and other gastrointestinal reactions, severe cases can also cause convulsions, coma and so on. Therefore, sprouted potatoes are not recommended to continue to eat after treatment. In addition, spoiled, green potatoes are not recommended for consumption.
