Food from the microwave. Are microwave ovens dangerous? What is a microwave and when was it invented?
Microwave ovens have taken a strong position in our kitchens. They significantly speed up the preparation and heating of food. Together with the undeniable merits of microwaves, their harmful effects on humans are also discussed. This is what my post is about today.
The history of microwave ovens
The very first patent for a microwave was issued back in 1946 in the USA. The world’s first microwave oven Radarange was released in 1947 by Raytheon and was not designed for cooking, but for the quick defrosting of food.
The installation was used only in the military. The size of the system was impressive – about the height of a person.
The mass of the furnace reached 340 kilograms. The initial power was 3 kW. The installation went to the serial production only in 1949. The official price in 1949 was $3,000.
How does a microwave work?
In order to warm up food, high-power electromagnetic waves are used in a microwave oven. They act on water molecules, penetrating into the structure of the products. Molecules start to move around the electromagnetic field and a friction effect is created, which causes the temperature of the food to rise. The whole process is carried out from the inside and takes only a few seconds, unlike usual ovens.
Is it more harmful or beneficial?
When food is heated in a microwave, its molecules move at a breakneck pace. Because of this, the integrity of the structure suffers. There is a deformation of the molecules and the disintegration of their shell. And at the output we get a product with a completely different molecular structure.
This is a scientific rationale for the harmful effect of a microwave oven on human health. Here are several factors that, according to experts, make the use of the microwave dangerous for humans:
– changes in the structure of food and as a result, that the food is more difficult to digest;
– the release of harmful carcinogens that increase the risk of cancer;
– the human body does not absorb the vitamins and mineral substances changed under the influence of electromagnetic waves;
– radiation can penetrate through the walls of the microwave oven and adversely affect the person;
– useful properties of food when heated in a microwave are lost and it becomes alien to the human body;
– a metal object that was inadvertently inside the furnace can lead to an explosion and injure a person

Swiss scientists conducted an experiment: they hired a man who was alternately fed food from a microwave and food cooked in the traditional way.
