Experts Warn People to NEVER Microwave These 10 Foods

We all love the microwave and its convenience, especially on our busiest days. Apart from being efficient and fast, microwaves are versatile, and you can use them to reheat food. While microwaves come in handy when you need to steam vegetables, bake a mug cake, or roast chicken, certain things should never heat in a microwave. 

Here are ten foods you should never microwave.

1. Hard Boiled Eggs

Avoid heating hard-boiled eggs in your microwave, as the hard shell can lead to an explosive situation. The water inside the hard-boiled egg and its impervious shell create an impenetrable barrier, leading to pressure buildup and, eventually, an explosion. It’s best to warm hard-boiled eggs in a water bowl or eat them cold in salads instead of microwaving them.

2. Broccoli

The Journal of the Science of Food and Agriculture revealed that microwaving broccoli could destroy its flavonoids. Flavonoids are anti-inflammatory compounds that help reduce your risk of heart disease. 

Nutritional experts recommend steaming or blanching your broccoli to preserve its nutrients. 

3. Processed Meats

You should never microwave processed meats like sausage or bacon, as this process leads to the formation of cholesterol oxidation products. These compounds can cause coronary artery disease and hardened arteries. 

4. Bread

Although putting bread in the microwave has no adverse health effects, you probably won’t enjoy the result after the bread cools down. Bread has a lot of starch, with sugar atoms that break down when exposed to high heat. The melted sugar crystalizes and makes the bread harder than before microwaving. 

5. Raw Hot Peppers

Raw peppers have capsaicin, a spicy flavor compound that vaporizes when you microwave them at high temperatures. Capsaicin is an irritant that leaves you with a burning sensation when exposed to your eyes, face, and the respiratory system. Exposure to this compound can also lead to difficulty breathing, coughing, and intense discomfort. 

Microwaving raw peppers can contaminate foods you might heat later, resulting in unwanted spiciness. Experts recommend roasting or sauteing hot peppers on a stovetop for even heating and better ventilation. 

6. Dark Green Leafy Vegetables

Kales and spinach are rich in iron and nitrates. However, when reheated, these nitrates convert into nitrites, which are known carcinogens.  The high iron content may also oxidize due to the high heat, causing free radicals that may expose you to diseases like cancer or infertility. It’s safer to steam, boil, or saute your leafy greens. 

7. Potatoes

Potatoes are rich in Vitamin C, potassium, and Vitamin B6. However,  reheating them in the microwave may produce clostridium botulinum, a bacteria that causes botulism. The condition causes toxins to attack the body’s nerves, leading to breathing difficulty and symptoms like diarrhea and nausea. 

8. Pizza and Tortillas

Reheating pizza in the microwave leads to a soggy and chewy crust as the heat agitates the water molecules. Microwaving also leads to uneven heating; you may find hot or cold spots in your pizza. The heat also causes a rubbery cheese texture, which makes the pizza lose its flavor and texture. Tortillas also become brittle, making them difficult to fold. 

The best alternative is to reheat your pizza in the oven rack for ten minutes or use a skillet. 

9. Frozen Meats

Avoid reheating frozen meat in microwaves. Doing so degrades the meat’s overall quality and could lead to food safety concerns. The uneven heating on some meat parts could allow bacteria such as E. coli and Salmonella to thrive, increasing your risk of foodborne illness. Rapid heating also breaks the meat fibers down unevenly, making the meat dry and rubbery. 

Nutritional experts recommend thawing frozen meat before reheating it. Then, you can use a stovetop or oven to reheat the meat for even and controlled heating. This ensures the meat retains a better texture and flavor. 

10. Fish and Seafood

Fish and seafood are delicate, and reheating them in the microwave only overcooks them, resulting in rubbery and dry meat. These foods also lose their flavor when reheated as the uneven heating strips away the natural oils and moisture that give the fish/seafood its taste. It makes it dry and rubbery. The high heat also creates a distinct smell that lingers for hours. 

The best way to reheat your fish or seafood is through steaming, which helps maintain its texture and moisture. Alternatively, you can use the oven and cover the fish and seafood on a baking sheet to retain moisture. 

Although the microwave is a convenient kitchen appliance, it should only be used in some settings. To preserve texture and flavor, avoid reheating the above foods in the microwave and instead opt for alternative methods like steaming, blanching, or using the oven.
