The microwave has changed the way we think about cooking for decades. A modern marvel, microwaving food does more than just reheat and cook food, it provides users with the priceless luxury of more time. Unfortunately, it is not safe to cook or reheat these foods in the microwave. While some of the foods on this list may be common knowledge, some of the foods on this list are both surprising and disappointing. If you’re thinking about re-heating that chicken and rice dish in the microwave tonight, you might want to read this first.



Okay, you’re probably thinking, “who puts celery in a microwave?”, but celery isn’t an uncommon addition to soups and dishes that are often reheated in a microwave. Celery contains a high nitrate content and when reheated in a microwave the nitrate in celery is converted into nitrite. Nitrite, in excess, is linked to certain cancers and can compromise the health of pregnant women and newborns. Remove the celery before reheating soup or other dish containing celery to avoid consuming the highly toxic compound. Carrots also fall under the same category as celery when it comes to foods to avoid microwaving

Leafy Greens

Spinach, kale and other leafy greens go from healthy to risky when heated in a microwave. Like celery, leafy greens contain high concentrations of nitrates which, when heated in a microwave, turn to nitrites. Not only does reheating in the microwave convert the nitrate to nitrite, but a host of carcinogens also become present. Carcinogens have been known to cause various types of cancers and other potentially fatal illnesses and disease. Besides, leafy greens are best eaten cold or chilled. Reheating in the microwave not only makes them bad for your health, it makes them taste bad too.
