Those odd little sprouts on your potatoes are your first clue that something inside has started to change. As they grow, the tuber ramps up production of natural toxins called glycoalkaloids—mainly solanine and chaconine. The plant uses them as a defense, but your body reads them as a threat. Nausea, cramping, vomiting, and headaches can all be the price of ignoring those signals.
You don’t have to panic at every tiny sprout, but you do need to pay attention. If the potato is still firm and its skin isn’t turning green, carefully cut away the sprouts and any damaged areas before cooking. However, once it’s soft, wrinkled, bitter-tasting, or covered in long, thick sprouts, it belongs in the trash or compost, not on your plate. A few seconds of inspection can spare you hours of misery—and turn a casual habit into a quiet act of self‑protection.
