Potatoes are green and it is best not to eat them.

Potatoes germinate and the skin of potatoes turns green, so you can't eat them, so you must pay attention when peeling potatoes. If you find that potatoes turn green, you must cut off the green part and try to cut as much as possible. If the green area is large, it is best to throw away such potatoes.

The green color of potatoes is the coloring of chlorophyll, which is not toxic in itself, but it reflects the increase of solanine content in potatoes. Solanine is a toxic substance, and 0.2-0.5g solanine is enough to kill an adult. This is the real reason why green potatoes are poisonous.

When potatoes are exposed to the sun for a long time, the amount of solanine in them will increase, which is a self-protection way for potatoes to prevent being eaten by herbivores. Solanine will make the taste of potatoes bitter. After eating potatoes containing solanine, you will feel thirsty, palpitation and shortness of breath, and even more serious, you will have mental disorder, hallucinations and paralysis.

Solanine exists in the whole potato, and the epidermis is more. Peeling can remove 30%-90% of the toxins, so it is best to peel potatoes and eat them. Once the potato turns green, don't be reluctant to throw it away, because at this time, the solanine content of the whole potato is already very high. Just cut off the green part and it will still be poisoned.
