4. Green Potatoes
When potatoes are exposed to light, they produce solanine, a natural toxin that can cause nausea, headaches, and neurological issues if consumed in high amounts. The danger signs are green patches on the skin or sprouting eyes. To stay safe, always peel away green areas and discard heavily green or sprouted potatoes. Cooking does not remove solanine, so prevention is key.
How to enjoy without risk: Store potatoes in the dark and discard green or sprouted ones.
