Really, I’ve so many questions. Are you able to slim off the inexperienced half and hope for the right? Or does the inexperienced tinge indicate the potato has gone harmful and it have to be thrown away? To hunt out out, I talked to a meals safety expert. Be taught on to be taught why potatoes flip inexperienced inside the first place, and whether or not or not they’re suitable for eating.
Why Do Potatoes Flip Inexperienced?
Potatoes are a root vegetable that develop underground, in order that they’re not uncovered to very lots mild. In step with Kali Kniel, PhD, professor of microbial meals safety on the School of Delaware, mild publicity can enhance the main target of chlorophyll inside potatoes, inflicting them to point out inexperienced on the pores and pores and skin.
In potatoes, the inexperienced hue might also level out an increase in a pure glycoalkaloid compound generally known as solanine. “That’s one objective it’s actually useful that potatoes are saved at nighttime and away from mild,” says Kniel.
In nature, these compounds play an important perform, serving to protect vegetation from fungi and bugs. Nevertheless everytime you eat a potato that’s developed these defending compounds, you possibly can uncover a bitter model—which is objective enough to suppose twice a few inexperienced potato for dinner.
Is It Protected to Eat Inexperienced Potatoes?
Positive, nonetheless with just some caveats. The U.S. Division of Agriculture recommends not consuming the inexperienced part of potatoes, nonetheless you don’t have to worry about tossing your complete issue.

The European Meals Safety Authority (EFSA) states that 1 milligram per kilogram of physique weight per day is the underside dose at which undesired outcomes are seen. So for those who occur to weigh 175 kilos, or nearly 80 kg, you’d have to eat 80 mg of glycoalkaloids a day (that’s masses) to notice ANY bothersome GI indicators—nonetheless most definitely way more to get really sick.
Plus, chances are you’ll protect your self from the potential opposed outcomes. “The hazard of consuming solanine might be diminished simply by peeling the potatoes, after which it is even further diminished by cooking,” says Kniel.
How To Appropriately Retailer Potatoes
To keep up your potatoes from turning inexperienced—and to help them final extra—Kniel recommends storing them in a cool, dry house that isn’t uncovered to mild, like a pantry shelf or a space for storing in your storage or basement.
