Why heating food in microwave is bad?

It is a known fact that plastic items tend to melt under excessive heat. This in turn exhibits harmful chemicals causing danger to human health and further polluting the environment. As research shows, this is the most perceived threat that comes from using microwaves.

What are the negative effects of microwaves?

Microwave radiation can heat body tissue the same way it heats food. Exposure to high levels of microwaves can cause a painful burn. Two areas of the body, the eyes and the testes, are particularly vulnerable to RF heating because there is relatively little blood flow in them to carry away excess heat.

Will reheating food kill bacteria?

Cooking and reheating are the most effective ways to eliminate bacterial hazards in food. Most foodborne bacteria and viruses can be killed when food is cooked or reheated long enough at sufficient high temperature. The core temperature of food should reach at least 75℃. … Cook with strong heat rather than low heat.

Can bacteria survive in a microwave?

Why you shouldn’t use a microwave?

It generates harmful compounds. Microwaves deplete the nutrients found in food. In addition, it replaces the healthy compounds of the dish with radioactive ones. This happens because microwave ovens use microwave ionization to heat up food. Ionization in controlled areas is found to be cancer causing in humans.

How far away from microwave is safe?
