ARE POTATO EYES POISONOUS?
If the eyes of a potato are not sprouting, they can be eaten. If they are sprouting, the National Institutes of Health recommends cutting off the eyes and their sprouts before eating the potato.
Potato stems, branches, leaves and fruits are toxic, containing alkaloids such as arsenic, chaconine and solanine. Solanine is "very toxic even in small amounts," according to the NIH.
Poison is also found in green potatoes. The vegetables turn green if they have had too much exposure to light. According to the NIH, you should "never eat potatoes that are spoiled or green below the skin."
