Is it healthy to microwave meals? Is it OK to use the microwave to heat meals?

Is microwaved food harmful?

1. Because microwaves are a type of radiation, there is a misconception that it causes cancer. In fact, microwaves are electromagnetic waves, essentially the same thing as radio waves, infrared rays, and vertical visible light used in radio and telegraphs. The only difference between them is the frequency.

The frequency of microwaves is higher than that of radio waves and lower than that of infrared and visible light. Electromagnetic waves in this frequency band are not carcinogenic.

2. Scientific research has found the minimum microwave power that causes harm to the human body, and has formulated the standard for the leakage power of microwave ovens. For example, the United States stipulates that the power per square centimeter should not exceed 5 milliwatts at a distance of about 5 centimeters from the microwave oven; The standard in our country is more stringent, which is 1 milliwatt. And the energy of the microwave is attenuated by the square of the distance.

At 1 milliwatt at 5 centimeters, it is reduced to 1 hundredth milliwatt at 50 centimeters. Therefore, as long as it is a microwave oven product with a sock compartment and is not damaged during use, it will not leak out microwave products that can harm the human body.

3. If the microwave oven is used for heating, it generally does not need to reach more than 100 degrees; For high-moisture foods such as porridge, soup, milk, rice, and noodles, as long as the water is not evaporated, the food temperature will always be maintained at 100 degrees Celsius, and carcinogens will not be generated. Therefore, normal use of microwave ovens will not cause carcinogens to be produced in food. Even according to relevant studies, microwave ovens can effectively reduce the production of the above-mentioned carcinogens compared with traditional heating methods, especially burning, grilling, frying, etc.

4. Some plastics may release some harmful components when heated. The U.S. Food and Drug Administration (FDA) has determined the amount of harmful substances that may be released into food in various plastic containers during normal microwave heating, and requires this amount to be less than one percent or even one thousandth of the harmful dose determined by animal experiments before it can be labeled as "microwaveable". Therefore, it is quite safe for those qualified plastic containers that are labeled as "microwaveable".

If you are not sure, you can also use ceramic or glass containers.

There is nothing wrong with using a microwave to heat meals, and microwavable meals are not harmful to a person's health.

Easy to useThe micro-panty oven is a convenient and fast way to heat up food in a short period of time, making it easier for people to enjoy warm meals.

Still, whether it's good to use the microwave to heat your meals depends on your personal preferences and needs. From a hygiene point of view, microwaving your meals will not make them unhealthy or harmful.

Fortunately, the food heated in the microwave oven may only be heated too much, resulting in the food not having a premature moisture difference and affecting the taste.

Remember to use materials that can be heated in the microwave.

Eating food heated in the microwave is not harmful to the human body and will not cause much impact on the human body.

Microwaving meals is harmless to the human body. However, the utensils used to heat food in the microwave oven should be ceramic, heat-resistant glass, etc., to avoid the production of harmful substances in plastic and other containers at high temperatures, which is not conducive to health. Microwaving meals is usually relatively simple to operate, and it can be heated in a few minutes or so.

There is an opinion that using a microwave oven also has certain risks and contains radiation components. In fact, microwaves are electromagnetic waves, essentially the same thing as radio waves, infrared, and visible light. No carcinogens are produced.

When you usually use a microwave oven to heat food, you must judge whether the food has deteriorated, and the spoiled food cannot be continued to eat, if you feel uncomfortable after ingesting it by mistake, you should seek medical attention in time for examination.

Microwave Precautions

Do not overheat: put the food in the microwave oven to thaw or heat, if you forget to take it out, if the time is more than 2 hours, you should throw it away, so as not to cause food poisoning. Do not put ordinary plastic containers in the microwave oven to heat

One is that hot food will deform the container, and the other is that ordinary plastics will release toxic substances that can contaminate food and endanger human health.

1. Metal containers.

Metal containers have always been unable to be used in microwave ovens, metal containers in the microwave oven will reflect microwaves, easy to produce crackling electric sparks, in layman's terms, you can understand that metal materials and microwaves in the microwave oven are conflicting, so some of your metal spoons, dishes, cups, etc. should not be heated in the microwave oven as containers.

2. Ordinary plastic containers.

Some ordinary plastic lunch boxes or cups should not be put into the microwave oven, only plastic containers suitable for microwave heating can be put in the microwave oven. Therefore, when buying a plastic lunch box, if you are thinking about using a microwave oven, then you should buy a version that is suitable for microwave heating.

3. Cartons and easy-to-expand packaging.

Some milk or drinks are packaged in environmentally friendly cartons, which are not suitable for microwave heating, and at high temperatures, paper has flammable properties, and it is dangerous to force the carton into the microwave oven as a food container. Moreover, the easily expanding packaging is not suitable for microwave ovens, and it is easy to cause danger once the high temperature expands and bursts.

4. Do not use closed containers.

Wide-mouth containers should be used when heating liquids, because the heat generated by food heating in closed containers is not easy to dissipate, so that the pressure in the container is too high, which is easy to cause blasting accidents.

5. Some ceramic utensils.

Nowadays, most ceramic containers are suitable for microwave ovens, and ceramic containers that cannot be used for microwave ovens are mostly because some of the paint surfaces on the containers are susceptible to high temperature melting and release harmful substances, and some ceramic containers are not resistant to high temperatures and are not suitable for microwave ovens.

The restriction on using the microwave for hot meals is mainly due to several reasons:

1.Uneven temperatures: When microwave ovens heat food, microwave radiation is used, which causes the food to heat locally on the inside, while the outside may still be cool or cool. This means that the food is hot and crispy unevenly, which can be scalding or uncomfortable.

2.Becoming moist on the outside: When you heat a meal in the microwave, the moisture inside the food may quickly heat up and create steam, causing the food to become moist on the outside. This can affect the taste and texture of the food and can destroy the original cooking quality of the food.

3.Deterioration of quality: Heating some foods in the microwave may cause deterioration of quality. For example, bread or pastries may become soggy and softened, while crispy foods may become soft or lose their crispiness.

Still, for some simple foods, such as quickly heating milk or hot water, the microwave is a convenient and quick heating option. However, for complex foods such as meals, it is easier to control and evenly heat the food using traditional heating methods such as stovetops or steamers, thus maintaining the quality and taste of the food.

When you use the microwave to heat your meals, take care to make sure the food is well heated and stirred to ensure even heating, and be careful to avoid burns. Also, depending on the type of meal and the power of the microwave, you may need to adjust the heating time and intensity accordingly. It is best to follow the instructions on the food packaging or professional recipes.

Yes, who says no, the microwave oven is meant to be a hot meal, take a closer look at the instructions to see what the microwave is for.

Frequent microwave heating of meals is not harmful to the human body.

The principle of microwave oven heating is to cause friction between molecules in food through microwave radiation, **, and generate heat, which is like two hands rubbing to heat up. The friction between molecules is called internal friction, and the internal friction produces more than 3,000 oscillations per second, and this is where the heat of the microwave oven comes from.

Therefore, microwave heating is only physical heating, which itself heats the food from the inside out, but does not cause chemical changes in the food, and therefore does not produce so-called carcinogens.
