It’s probably happened to you: you’re rummaging through the corner of your pantry when you come across a sack of potatoes with a few pointy sprouty things sticking out every which way. You vaguely remember hearing something about the sprouts being poisonous. Or was that an old wives’ tale? Do you toss ‘em or break out the peeler and masher?
It turns out that the sprouts do contain potentially harmful concentrations of glycoalkaloids, compounds that can have toxic effects. But sprouted spuds aren’t necessarily duds: the root itself is likely still safe to eat, so long as you cut away the little growths.
In a paper published in the Journal of Agricultural and Food Chemistry, USDA research chemist Mendel Friedman explains that “glycoalkaloids are produced in all parts of the potato plant including leaves, roots, tubers, and sprouts.” When consumed in large enough doses, glycoalkaloids can have some pretty nasty effects, like nausea and vomiting. The levels of these compounds in the root itself are generally too low to have any bad effects. But “sprouts contain higher levels than do leaves or tubers,” therefore it’s best to avoid them.
Friedman mentions that “light and heat or mechanical injury stimulates glycoalkaloid synthesis,” which is why it’s a good idea to store your potatoes in a dark place. Light also encourages chlorophyll formation, which is harmless in itself. But it causes potatoes to turn green in the same areas that are at the most risk for being poisonous, acting as a visual clue for the parts you should avoid.
The USDA recommends that “if a potato has begun to grow sprouts, cut off the sprouts before cooking” and to “cut off any skin that started to turn green.” The remainder of the potato should be safe for consumption. If you do notice an unusually bitter taste in the potato, however, this could be a sign of increased glycoalkaloids in the root. It should not be eaten.
