18 Regular Foods that When Microwaved Turns into Harmful Toxic Poison | Food Hacks for Microwave

Microwave ovens are handy appliances and the best gift or technology on busy weeknights.

Between warming up your favorite hot beverage that has gone cold, reheating a pizza, heating up the dinners or leftovers at your office, there's little doubt you use the microwave more than you think.

However, certain things should never be put into the microwave. You've undoubtedly heard about the containers and wraps that cause fires, melt, or radiate harmful toxins. However, you must not have thought about the foods that shouldn't have gone into the microwaves.

Wait, really? It turns out that there are numerous foods and food products. These include some of them that you regularly microwave. From toxins, explosions to ineffectiveness to burns, there are several reasons why these foods should never be microwaved.

Read on to find more about the foods that must stay out of the microwave and why.

Eggs in Shell

Beware! You should definitely never try hard-boiling eggs into a microwave. It might seem like beyond a genius life hack, it is dangerous. The high temperatures in the microwave create steam within an egg, and as the pressure builds, it will cause the egg to explode. Well, that's not great!

Chilli Peppers

The Daily Meal states that the capsaicin (the compound of the peppers that determines its spiciness) present in the peppers vaporizes when exposed to high heat inside the microwave. While the peppers remain unexploded, fumes given off should be avoided, if possible.

Breast milk

Many moms pump and store their breast milk into a freezer. It is then thawed and given to the baby when needed. However, you require being careful enough about how exactly you thaw and heat the frozen breast milk.

In the view of The Food and Drug Administration (FDA), thawing and heating the breast milk in the microwave can heat it evenly. However, it creates hot spots that are dangerous and might scald the sensitive palate of babies.

A mug of water

Heating up a mug of water for preparing hot tea, coffee, or for other purposes seems to be regular use of your microwave. Right? It is convenient and quicker than doing the same in a kettle, especially when you lack the one that runs on electricity.

However, according to The Daily Meal, when you are heating a mug of water in a microwave, it superheats the water, rather than boiling it. Then, when you add a tea bag or stir the liquid in the mug, it boils rapidly, which causes spillage or explodes, burning you dangerously.

Processed meats

Microwaving hot dogs is a bad idea. Sounds silly. Right? According to research published in the journal Food Control, microwaving processed meats (especially that are full of preservatives) lead to the formation of cholesterol oxidation products (COPs). A study conducted by researchers in 2006 in India states that these COPs have previously linked to coronary heart disease.

Microwaving lousy food is the easiest way to make it worse. It is advisable to indulge the same on a stove.

Leafy greens

Microwaving the leafy greens are a bit dangerous. A report produced by NPR states that kale and other such vegetables spark when microwaved. Thereby destroying singeing your dinner along with damaging your appliances. It is not a great decision when you are trying to make a healthy dinner.


Olive, grape seed, canola, avocado, peanut, and other oils used for cooking aren't liquids, but fats. According to Prevention, heating an oil, like, olive oil in the microwave for either cooking or in beauty products does not pose danger. However, it is not a productive action because there is not any liquid within the olive oil to heat. It won't be warmed as you would've liked.

Red pasta sauce

If you love cooking and heating the red pasta sauce in a microwave, you have experienced the mess it creates. Spitting, splattering, and exploding all over the surface when it takes a turn, no matter how brief.

Jon Hotchkiss, the creator of This vs That, in a piece for HuffPost, wrote, "the [insoluble] fibrous tomato chunks only block the steam's escape temporarily — that is, until such point as the volume and strength of steam overpowers the chunks... and thus causing an 'explosion'."

The red pasta sauce and other tomato-based sauces have an overall viscosity quite similar to water. They wouldn't make a mess of your microwave when they are reheated. Instead, warm the sauce low and slow in a saucepan on the stove. The sauce will have some consistency as a sauce rather than drying out, and you'll be happy because the microwave stayed spotless.

If you are microwaving grapes, the result will be just the opposite than you expect. Astonished? As noted by IFLScience, you won't get raisins or roasted grapes. Instead, you could end up with balls of fiery plasma. It's dangerous!

Uncooked rice

Microwaving uncooked rice? Never do so! Why? According to the Food Standards Agency of the UK, rice becomes house spores of bacteria that cause potential danger. Microwaving it cannot kill those spores, thereby leaving you potentially susceptible to food poising.


In most households, broccoli takes a regular turn in the microwave. Wait, what? A study published in the Journal of the Science of Food and Agriculture in 2003 reports that it really shouldn't.

When compared with other popular cooking methods for broccoli, microwaving destroys far more good nutrients that you might typically get from eating those tiny green trees. It is better gently steaming the broccoli before eating it so that you never lose the nutrients fr
