One, microwave ovens have radiation and are harmful to the human body?

The microwave oven is a very popular small kitchen appliance that can not only quickly defrost and heat all kinds of food, but also make a variety of gourmet food, efficient and convenient, loved by families and office workers, even many companies will have a microwave oven to warm up the staff.

However, over the years, there have been many rumors about the microwave oven, such as the radiation generated by the microwave oven is harmful to humans, and the microwave oven heats food not only to lose nutrients, but also to produce carcinogens, etc. But is the microwave oven really that terrible?

First of all, radiation is generally divided into two types, ionizing radiation and non-ionizing radiation. The first is that the company's products are not only in the market, but also in the market. Non-ionizing radiation refers to radiation with low energy, which does not have the ability to interrupt DNA and cause genetic mutations, and generally does not pose a health risk. And the radiation produced by microwave ovens is non-ionizing radiation, and there is no scientific evidence that they pose a cancer risk.

Then, look at how a microwave oven works. It uses an internal magnetron to convert electrical energy into microwaves for a short period of time, currently typically at 2.45 GHz, which means that the molecules within the food can vibrate 2.45 billion times per second, generating a lot of heat in a short period of time, but without changing the chemical bonds of the molecules.

Dr. Yun Wuxin, a food engineering doctor, said microwaves are a type of non-ionizing radiation, but they are actually an electromagnetic wave, which is essentially the same thing as the electric waves and visible light used in everyday radio and telegraph. The company's main goal is to provide a comprehensive range of products and services to help you achieve your goals.

The director of the comprehensive inspection department of the National Center for Household Appliance Quality Supervision and Inspection Lu Jianguo pointed out that the quality of qualified microwave ovens are strictly tested and repeatedly experimented with, and the radiation generated during their operation is within the national standard, and normal daily use will not bring harm to the body.

Two, microwave heating of food, can cause cancer?

Even though microwaves are known not to affect health, many people worry that microwaved food can produce carcinogens inside.

Whether food is carcinogenic or not depends on the cooking temperature. Under high temperature cooking, harmful substances such as polycyclic aromatic hydrocarbons, heterocyclic amines and acrylamide are produced, which do have a certain risk of causing cancer when they enter the body.

Which is more likely to produce carcinogens, microwave heating or traditional cooking?

Some scholars have compared the carcinogens produced under several cooking methods and found that microwave heating does not produce more carcinogens. The microwave oven relies on electromagnetic waves to heat food without an open flame, and the cooking temperature is generally lower than traditional ones, making it less likely to produce carcinogens by comparison.

As for whether microwave heating of food will lead to nutritional loss of food, Fan Zhihong, an associate professor at the School of Food, China Agricultural University, pointed out that for food with high moisture content, as long as it is heated at the right temperature for the time, it will not lose more nutrients than other ways. And vegetables and fruits and other foods in the microwave cooking, the loss of vitamin C, chlorophyll and so on inside is relatively small. However, some fish may have a decreased proportion of omega-3 fatty acids after cooking in the microwave, and it is recommended to choose steaming and other ways to preserve nutrients as well.

Three kinds of food can't be heated in microwave ovens, although they are good

It is important to note that although microwave ovens are good, not all food can be heated in them.

Three kinds of food cannot be heated in the microwave

Three kinds of containers can not be used in microwave ovens

Microwave ovens, as one of the most commonly used household appliances, do not pose a health risk under normal use, so there is no need to worry too much about it.
