Sprouted or green potatoes contain concentrated toxins that heat cannot destroy, making them unsafe to eat.
Throwing away potatoes that have begun to sprout is the safest choice for your health. The tubers naturally produce toxic compounds called glycoalkaloids as a defense mechanism against fungi and insects. While healthy potatoes contain these substances at safe levels, the concentration skyrockets to dangerous amounts once sprouts or green patches appear — and no cooking method can eliminate the poison.
These toxins are typically concentrated in the skin, green areas, and damaged parts of the potato. Peeling the skin and removing very small sprouts can reduce the toxin content by 30 to 80 percent. However, large sprouts or green discoloration that has spread into the flesh indicate the toxins have permeated the entire potato. In such cases, the potato is unfit for human consumption and must be discarded immediately — especially if the tuber feels soft or gives off a strong musty or earthy odor.
Consuming high amounts of these glycoalkaloids triggers health problems that begin in the digestive system. Symptoms include abdominal cramps, a bitter taste in the mouth, nausea, and vomiting — all appearing within hours of eating. In severe cases, the effects can extend to the nervous system, causing hallucinations, dizziness, and jaundice. Very rarely, extremely high doses may lead to coma or heart failure.
Experts recommend following correct storage methods to keep potatoes safe and prevent sprout growth. Buy small quantities based on immediate need. Store them in dark, cool, well-ventilated places away from direct sunlight or the heat of electrical appliances. Do not put uncooked potatoes in the refrigerator. Use perforated plastic bags to allow air circulation, which extends shelf life and keeps natural toxin levels within safe limits.
