The Dangers of Microwaves and Their Effects on Our Food

America’s most convenient appliance – microwave ovens seem to be an absolute necessity in today’s fast-paced world. They are currently present in at least 90% of homes in America thanks to their ability to cook and reheat foods or beverages in a simple, rapid way. The majority of people use this kitchen appliance without question and often thing microwaves just a simple alternative to conventional ovens. This page is here to tell you to think twice before using your microwave, as it could be one of the worst things you do for your own food.

What are microwaves and how do they work?
In short, microwave ovens are kitchen appliances which are used to cook or reheat food by emitting microwaves. Microwaves are a form of electromagnetic radiation and are on the low energy end of the energy spectrum, second to radio waves. The waves are generated by something called a magnetron – something found within every microwave oven.

Magnetrons produce an electromagnetic field with a microwave frequency of approximately 2,450 megaHertz (MGz), which is the equivalent to 2.4 gigaHertz (GHz). Microwaves produced within the microwave oven cause dialectric heating – they bounce around the inside of the oven and are absorbed by whatever is placed in the oven.

In order for something to heat in a microwave oven, water must be present within the substance. If water is not present, heating will not occur and it would remain cool. The reason for this is that water molecules within the food vibrate at incredible speeds, creating molecular friction which is responsible for the heating of the food. The structure of the water molecules are torn apart and vigorously deformed. This is much different than any other method of cooking, as other methods such as convection ovens heat up food by transferring heat convectionally from the outside inward. >
