What does it mean if a potato is green when you peel it?

A green potato is a sign that it has been exposed to light, causing the production of solanine. Solanine is a natural toxin that can make you sick.

Here's what you need to know:

* Green skin: This is the most obvious sign of solanine buildup. The green color is caused by chlorophyll, which is produced when potatoes are exposed to sunlight.

* Green flesh: Even if the skin isn't green, the flesh of the potato might be. This means the solanine has penetrated deeper into the potato.

* Bitter taste: Solanine has a bitter taste. If your potato tastes bitter, discard it.

* Symptoms: Eating too much solanine can cause nausea, vomiting, diarrhea, abdominal cramps, and headaches. In severe cases, it can lead to paralysis and even death.

What to do with green potatoes:

* Do not eat them.

* Cut off the green parts: If the greenness is only on the skin, you can cut it off and eat the rest of the potato.

* Discard the potato if the flesh is green: If the greenness has penetrated the flesh, the potato is no longer safe to eat.

Tips to prevent green potatoes:

* Store potatoes in a dark, cool, dry place.

* Don't leave potatoes in direct sunlight.

* Use potatoes within a few weeks of purchasing them.

Remember: It's always better to err on the side of caution. If you're unsure about a potato, it's best to discard it. Your health is more important than saving a few potatoes.
