Potatoes with a little sprout can be removed before eating, while peeling the skin will be thoroughly dug around the small sprout, remove the green, purple, turning green part, to be safe you can place the potatoes in cold water, soak for half an hour before cooking, cooking with the right amount of vinegar, can play a role in neutralizing the toxins. After the above treatment, the potatoes can be eaten. Normal potatoes also contain certain toxins, mainly lobotoxin, but this toxin is soluble in water and can be absorbed into the body and dissolved in the blood, which has a certain corrosive and irritating effect on the gastrointestinal mucosa and can paralyze the respiratory center and lead to brain edema in severe cases. The potatoes with a little sprout contain less toxins, and when eating them, pay attention to dig out the eyes of the sprouts thickly, so there is generally no problem of poisoning and they can be eaten. However, potatoes with more sprouts and heavier discoloration should not be consumed because they contain a higher amount of lobotropin, which may cause itching of the oral mucosa, nausea, vomiting, diarrhea and other symptoms if consumed. The milder ones may heal themselves, while the heavier ones will have worse symptoms and may even die due to respiratory paralysis.
