Are reheated potatoes safe? Debunking the toxic myth
Potatoes are a staple on many of our plates. However, some people wonder if they are safe to eat after being reheated, such as the next day. You've probably heard the claim that "reheated potatoes are poisonous." Sounds alarming, right? Let's take a closer look at this.
Concerns often arise about solanine, a natural chemical compound found in the green parts of potatoes. There's no need to worry here: solanine does not form when reheating potatoes. If the potatoes are healthy, not green, and properly cooked, reheating them does not pose a risk. The real issue is poor storage conditions—for example, leaving them in a warm place for several hours, which can encourage the growth of bacteria, especially Clostridium botulinum.
How to safely reheat potatoes?
If you want your potatoes to remain safe to eat the next day, store them in the refrigerator in a closed container. Avoid leaving them out on the kitchen counter overnight. Ideally, you should reheat them only once—in the oven, on a skillet, or in the microwave until they are hot in the middle. Repeatedly reheating them can promote the growth of harmful bacteria.
Are reheated potatoes healthier?
Many people aren't aware that as cooked potatoes cool, some of the starch transforms into what's known as resistant starch. While more difficult to digest, it benefits the intestines, much like fiber, by supporting a healthy gut flora. So, cold or reheated potatoes may actually be beneficial for our digestive system.
Feel free to eat reheated potatoes, but do so wisely
That's why you can definitely eat reheated potatoes, provided they are stored and reheated correctly. They are neither poisonous nor dangerous—it's simply a culinary myth that lacks scientific backing. So if you have leftover mashed potatoes or roasted potatoes from yesterday, go ahead and reheat them. Add a fried egg, some dill, and enjoy a delicious, guilt-free meal.
