Microwave oven can be said to be a very common household appliance now, but do you know what the harm of microwave oven is? Do you know what to pay attention to when using microwave oven? Do you want to know which foods can't be used in the microwave oven? The following is my collection of the hazards of using microwave ovens. I welcome your reference and hope it will help you.

Harm of microwave oven heating rice

1, microwave food will produce new toxic and even carcinogenic compounds.

The function of microwave oven is much more than just heating objects. The molecules of food absorb a lot of energy, which is enough to decompose the molecular structure of protein, leading to molecular variation that does not normally occur. As a result, many new and strange molecules appeared. That's the problem. The molecular structure of food has changed, resulting in molecules that the human body cannot recognize. These strange new molecules are unacceptable to the human body, some of which are toxic and may cause cancer. Therefore, people or animals who often eat microwave food will have serious physiological changes in their bodies.

The Soviets found that no matter what kind of food is heated by microwave, it will produce known carcinogens. Meat, milk, grains, fruits and vegetables all produce chemicals that cause cancer. In addition, the researchers also found that people who eat microwave food have disorder of digestive system, disorder of lymphatic system and increase of cancer cells in blood. Statistics show that people who often eat microwave food are more likely to suffer from gastrointestinal cancer and their digestive system will gradually collapse.

2. The nutritional value of food is seriously lost.

The Soviets also found that the nutritional value of all the foods in the experiment was reduced. The nutritional value of microwave food has decreased by 60% to 90%, including minerals and biochemical enzymes, vitamins B, C and E, and anti-fatty substances. Even the nutritional components in protein have decreased.

3, mood swings, memory loss

Long-term consumption of microwave food will lead to permanent brain damage, resulting in memory loss, inability to concentrate, mood swings and mental decline.

Therefore, the use of microwave ovens needs to pay more attention to some matters:

1, the prepared food is medium-cooked.

In order to prevent repeated loss of vitamins, it's best to only cook the food medium-ripe when taking meals. You can put out the food you want to bring when the food is fried to the middle of maturity, and then eat the rest when it is cooked. In addition to vegetables that may cause poisoning, such as beans, this can retain more vitamins in vegetables and taste more delicious. The red-cooked chicken and fried pork slices in the meat dishes are made into medium-cooked, and the taste will be better if they are reheated before eating.

2. Use utensils marked with microwave oven.

Be sure to choose a lunch box suitable for microwave heating. Such a lunch box will be marked with the words "Suitable for microwave oven". Plastics are not marked. Poor lunch boxes are easy to dissolve substances into meals when heated. Some plastics may release some harmful ingredients when heated, polluting food and endangering human health. Don't use metal utensils, because iron, aluminum, stainless steel, enamel and other utensils put into the furnace will generate electric sparks and reflect microwaves when heated by the microwave oven, which will not only damage the furnace body but also heat food.

3. Cover and heat

When heating, in order to prevent excessive evaporation of water, the cover should be covered for heating. Under normal circumstances, the time for heating the box lunch in the microwave oven is controlled at about two minutes. If the food is not hot enough, put it in the microwave oven and turn it around a little. If there is no bowl cover, wrap it with plastic wrap and wrap it instead. You can also sprinkle a little water on the surface of the food.

4, heating time should not be too long.

Heating time should not be too long. If the food is thawed or heated in the microwave oven, if you forget to take it out, if it takes more than 2 hours, you should throw it away to avoid food poisoning.

5. Don't leave food for too long.

Generally, the food prepared should not be kept for too long. It is best to get up in the morning to cook within 8 hours, so that the food is not easy to deteriorate and have bacteria. If there is no time, it can be stored in the refrigerator.

6, liquid heating to put a spoon.

If you want hot soup, you'd better put a nonmetallic stirring stick or spoon in the container, unless you want to watch the hot water splash show.

What can't microwave heat?

1, avoid heating the meat until it is half cooked before heating it in the microwave oven.

Because bacteria will still grow in semi-cooked food, it is impossible to kill all bacteria when heating in microwave oven for the second time because of the short time. Frozen meat must be thawed in the microwave oven before being heated into cooked food.

2. Avoid freezing the meat thawed in the microwave oven again.

Because after the meat is thawed in the microwave oven, it has actually heated the outer layer at a low temperature. At this temperature, bacteria can reproduce. Although refreezing can stop its reproduction, it cannot kill the living bacteria. Meat that has been thawed in the microwave oven must be heated until it is fully cooked if it is frozen in the refrigerator again.

3, avoid fried food

Oil will splash at high temperature, which will lead to fire. In case of accidental fire in the furnace, don't open the door, but turn off the power first, and then open the door to cool down after the fire is extinguished.

4, avoid overtime heating

If the food is thawed or heated in the microwave oven, if you forget to take it out, if it takes more than 2 hours, you should throw it away to avoid food poisoning.

5, avoid using ordinary plastic containers

Use special microwave oven utensils to hold food and heat it in the microwave oven. First, hot food will deform the plastic container. Second, ordinary plastic will release toxic substances, pollute food and endanger human health.

6, avoid using metal utensils

Because of the iron, aluminum, stainless steel, enamel and other utensils put into the furnace, the microwave oven will generate electric sparks and reflect microwaves when heating, which will not only damage the furnace body but also heat the uncooked food.

7. Avoid using closed containers.

A wide-mouth container should be used when heating liquid, because the heat generated by food heating in a closed container is not easy to dissipate, which makes the pressure in the container too high and easy to cause blasting accidents. Even when cooking food with shells, you should pierce the shells with needles or chopsticks in advance to avoid bursting after heating, splashing and polluting the furnace wall, or splashing and injuring people.

Conclusion: Have you all remembered the hazards of some microwave ovens introduced above? Are there any foods that can't be heated in the microwave oven? Everyone must be careful when using the microwave oven!
