Should we use Microwaves to cook our food? By:Kiahna


I believe that using a microwave is not bad. The Microwave has a electric tube called a magnetron. It produces electromagnetic radiation.  The Magnetron inside the oven changes regular electric power from a wall socket into super short radio waves. They are about four inches from crest to crest. They are made when the microwave's magnetron is at a frequency of 2450 megahertz. When  something gets to that frequency the power is absorbed and absorbed  by water, fats, and sugars, that become  very fast vibrations and high temperatures that cook the food.   
           
Microwave ovens  heat food by making radiation which is caused by the water molecules being  absorbed. It  makes the water molecules vibrate and makes heat and then cooks the  food.  Almost all ovens that are made  recently are safe to use as long as you follow the instructions. Almost everyone has a microwave, some people think that cooking food in a  microwave can harm you. They think that it gets rid of all the nutrients.
           
Microwaves do spill out some radiation, but that is the same as using a cordless phone, cellphone, laptop. They turn on and off like a lightbulb. It does make radiation waves so when it is on it is better to stand away. When the microwave is off the waves can’t emit. They also can’t flow around in the oven  and get into the food.


It is actually better to cook your vegetables in the microwave because it cooks them fast and it doesn’t use as much as water as steaming does. Using a microwave is very helpful but you need to use microwave safe containers. Microwaves will kill bacteria when a food is cooking, microwaving is safe.
