Some people like to cook potato skins together, so can the potato skins be eaten? We don't recommend eating potatoes with skins, especially those that have turned blue or sprouted.
Under normal circumstances, the content of this toxin in potatoes is very low and will not cause poisoning problems. The measured data published in China 1995 showed that the lowest content was in the peeled part of common potato, and the content in100g potato meat was only 0.014g in terms of fresh weight. If you want to eat with the skin, the content is slightly higher, which is 0.026 g, but if the potato turns green, the content of the green part of 100g rises to 0. 156g, while the germinated part is 0. 179g. ..
What is the standard for safe eating?
If you want to eat a lot, the content of100g fresh food is better than 0.020g.. For this toxin, the semi-lethal dose of rats is 75 mg/kg, which is equivalent to a person weighing 50 kg eating 3.75 grams a day, which is equivalent to eating 15 kg of potatoes with skin. Divide this amount by 100, and if you eat 150 grams of normal potatoes every day, you will still not be poisoned.
