Hard-boiled eggs
Whether or not boiled eggs have a shell, it is not recommended to put them in the microwave. During microwave heat treatment, a huge amount of steam accumulates in the eggs, which can turn them into something like a pressure cooker. The egg may explode, crack inside the microwave oven, or even damage it.
Processed meat
Processed meat contains a significant amount of preservatives and flavor enhancers that extend the shelf life of the product. These substances can become toxic in the microwave. According to the Journal of American and Food Chemistry, they undergo chemical changes, such as oxidation of cholesterol during reheating. Research suggests that reheating processed meat in a microwave oven can lead to oxidative processes in foods that are potentially carcinogenic.
Potatoes
It is not recommended to heat potatoes in a microwave oven, especially in aluminum foil, as this can cause C. botulinum to multiply and cause infections such as botulism. The microwave oven is not capable of killing such bacteria. It is advisable to cook and preheat the potatoes in a regular oven.
Grapes
You are unlikely to heat grapes or any fruit in the microwave unless they are in a dish, pastry, sauce or beverage. However, this is not the best idea, because grapes are very rich in water, which expands when heated and can burst, scatter over the entire surface of the microwave oven, as well as worsen the condition of the dishes in which it is.
Red pepper
Hot pepper contains the substance capsaicin, which gives them a sharp taste. This biochemical compound can become even more active after reheating in a microwave oven, saturating the air in the room and causing breathing and eye problems.
Beets
Like leafy vegetables, beets also convert nitrates to nitrosamines. A microwave oven can also change the taste of this root.
Leafy vegetables
If you plan to cook or reheat green leafy vegetables, it is better to do it in a standard oven than in a microwave oven. In the microwave, nitrates in vegetables are converted to nitrosamines, which can be carcinogenic, writes thehealthy.com.
Chicken
A microwave oven for chicken does not always kill bacteria. This also applies to chicken. It contains many bacteria that are potentially dangerous to the human body. Salmonella is one such bacterium. It is impossible to completely neutralize it in a microwave oven. Therefore, cooking chicken there is not recommended.
Figure
It may seem that rice is suitable for heating in a microwave oven, but this is not the case. The problem with rice can be due to the fact that it contains certain bacteria that can leave their spores in the rice, because the microwaves are not enough to kill them. According to a study published in the International Journal of Food Microbiology, the bacterium Bacillus Cereus is surprisingly resistant to microwave heating. Its spores can cause food poisoning if they multiply in the digestive tract.
Breast milk
Many mothers freeze milk and then heat it to offer the baby. If you do, you are not doing anything wrong. This method is allowed by doctors, but it is important not to overheat the milk in the microwave, no matter how much time you have. The liquids in the microwave are heated unevenly. This means that there may be hot spots in the milk that
