Eat But Don’t Reheat These 9 Popular Foods

Are you one of those people who despise leftovers or knows someone who does? It doesn’t matter if the food came from a restaurant or Mom’s oven, it ain’t gonna happen. Or could you be a leftover advocate, noshing on last night’s stew at work or giving it a makeover for the next night?

Whether the no leftovers crowd’s stance is due to an inner knowing, scientific slant, or plain old being grossed out, it seems there’s some merit to it. The list below shows nine foods that are not the best for reheating due to them becoming toxic or causing digestive issues. You may be surprised at the who’s who of reheat villainy.



My heart is breaking a little bit over this one. Reheating potatoes can promote the growth of botulism, a form of food poisoning caused by C. botulinum bacteria. Leaving them out or wrapped in foil to sit beyond two hours is a recipe for disaster. The warmth from a reheat provides a breeding ground for the bacteria instead of killing it off.


When chicken is eaten the next day it should be done cold or reheated at a low temperature for a long time. The dense proteins in chicken change after being refrigerated overnight and sent to heat-up heaven. This can cause major stomach upset. Microwaves don’t do a particularly good job in this instance, so find a way to reheat it once where the inside can get extra hot.


Like chicken, mushrooms have specific proteins that can cause gut or even heart problems if reheated the day after. Preferably, you want to eat these the same day. For leftovers, eating them cold will help deter the issues that their broken-down proteins can trigger.


A staple food across the globe, rice has a high risk of contamination. It can contain harmful spores that are present before cooking and toxins that don’t get destroyed during the cooking process. The worst thing you can do is leave rice out at room temperature, giving the bugs a cozy place to incubate. Your best option is to let it cool out in the fridge within a couple of hours of cooking to make reheating safer. Oh, and watch out for those suspect buffets where rice might be recycled!



Oils with low smoke points can become rancid or turn into trans-fats when exposed to high temperatures. These include hazelnut, avocado, walnut, or grape seed. Use them at room temperature as a drizzle instead.


As with beets, the turnip is a root vegetable that gets exposed to nitrates in the soil. Cook and consume the same day to avoid the risk of carcinogenic nitrates, or pluck them out of your leftover stew before eating.


A common ingredient in soups, celery contains nitrates which convert to nitrites when reheated. Nitrites are toxic and linked to carcinogenic risks, and it’s suggested to remove celery and other nitrite containing veggies before reheating.

According to the USDA and the Food Standards Agency, cooling and storing foods properly is the key to preventing foodborne illness or death. Such agencies note that it’s common to see an uptick around the holidays. It’s suggested to get your food into the refrigerator in the 2 to 4 hour range, and eat it within a day or two. Keep it any longer than that and you may be courting sickness.
