Can you eat the green parts of a potato plant?

Here's why:

* Solanine: The green parts of potato plants contain a toxic compound called solanine. This compound can cause nausea, vomiting, diarrhea, headaches, and in severe cases, even death.

* Sunlight: Potatoes turn green when exposed to sunlight because they produce chlorophyll to photosynthesize. This process also increases the solanine content in the potato.

It's always best to err on the side of caution and only eat the starchy tubers (the potatoes themselves) and avoid the green parts, leaves, and stems.
