Microwave oven can be said to be an indispensable household appliance in modern families, which brings great convenience to people’s fast-paced life. But when we use the microwave oven, we only pay attention to its rapidity, and its harm is often ignored. So what harm will long-term use of microwave ovens bring to our health, and how can we effectively avoid or reduce this harm? The following is an explanation for you.
The microwave oven has made a great contribution to the fast-paced life today. You can use it to cook food, thaw and heat food quickly, and even bake cakes instead of the oven. But we should pay more attention to the harm of microwave oven.
first, microwave foods produce carcinogenic compounds some studies have shown that microwave treated meat can produce carcinogens; Amino acids in milk, fruit and cereal will also be converted into carcinogens after microwave irradiation; The plant alkaloids in vegetables will also be converted into carcinogens after microwave, which will harm our health.
Second, food nutrition is seriously lost food cooked in microwave oven will greatly reduce the minerals, vitamins and nutrients in vegetables, or turn them into carcinogens.
Third, there will be certain changes in the body for example, hormone disorders, lymphatic and digestive system disorders, abnormal blood and immunity, low mood, memory degradation, permanent brain damage, and even heart disease.
Seeing the harm of microwave ovens to us, are you also shocked. So what mistakes will lead to such harm in the use process?
first, the misunderstanding of cooking containers
Maybe you are used to throwing packaged food together with plastic lunch boxes into the microwave oven for heating, which is absolutely not allowed. Because plastic containers will deform during heating, and release toxic substances to pollute food, which will cause cancer in the long run.
In addition, it should be noted that metal containers are also undesirable, because sparks will be generated when heating in the microwave oven, which will not only damage the furnace body but also cause explosion. We should use a special container for microwave oven to heat food, and do not cover the container tightly during the heating process, because the heat generated by food heating in the closed container is not easy to be dissipated, which makes the pressure in the container too high and easily leads to explosion accidents.
▲ avoid heating food with metal or plastic containers.
Second, misunderstanding of heating time
People often put food into the microwave oven to thaw or heat, and sometimes forget to take it out, leaving it for several hours. If you forget to take it out for more than 3 hours, you’d better throw it away to avoid food poisoning. Moreover, food heated for too long is easy to dry out due to the rapid loss of water, which not only makes it taste bad, but also greatly reduces its nutritional value.
▲ the heating time should not be too long
Third, mistakes in freezing or heating
Heating half cooked meat in the microwave oven until it is fully cooked can shorten the cooking time, but bacteria will still grow when the food is half cooked. When it is heated in the microwave oven for the second time, the time is too short to kill all the bacteria. In this case, you can thaw the frozen meat food in the microwave oven first, and then heat it to cooked food, so that you can eat it safely.
▲ pay attention to heating or thawing food with microwave oven
In addition, the same is true when thawing. Meat thawed in the microwave oven should not be frozen, because after thawing in the microwave oven, the outer layer of meat has actually been heated at a low temperature. Under this temperature, bacteria can reproduce, but freezing again can not kill live bacteria. If you have thawed the meat in the microwave oven, you can heat it until it is fully cooked before putting it in the refrigerator.
Fourth, the food to be heated is taboo
It is better not to fry food in the microwave oven, because the high temperature will make the oil splash, leading to fire. If there is a fire in the oven, do not open the door of the microwave oven. Cut off the power supply first, and then open the door after the fire is extinguished. In addition, when cooking food with shells, the shells should be punctured first to avoid explosion.
▲ microwave oven explodes and catches fire
fifth, mistakes in placement
Because the microwave oven has radiation, do not put it in the bedroom, but try to put it in a ventilated place. Besides, it is necessary to keep a certain distance from the TV and radio, otherwise the audio-visual effect will be affected.
After starting the micro furnace, it is better to keep a distance of 1m from it and not to look directly at it. Otherwise, it will cause dizziness, dizziness, fatigue, emaciation, hair loss and other symptoms.
▲ after the microwave oven is turned on, do not look directly at it
