What's with Microwaves?



In today’s society, most people have no idea how everyday items work. We go about our daily lives using machines that we have no understanding of how they work. Earlier in the week I asked 50 people, “How often do you use a microwave for heating or cooking?” 33% of those people said they use a microwave 3 times a week. In the hope of shedding some light on our seemingly dark world, I decided to investigate microwave ovens (or microwaves for short).

Microwave ovens use microwaves; a concept not hard to understand. What’s interesting is how it uses microwaves to heat up food or water. Microwaves are electromagnetic waves with alternating electric and magnetic fields. Since the electric fields alternate between positive and negative, when they hit a molecule they cause the molecule’s electric field to shift back and forth causing the molecule’s particles to move. The movement of the particles causes friction, and friction causes heat. Microwaves ovens basically use microwaves to make the molecules in food vibrate and make friction, which in return, heats the food up. This is why you sometimes have cold spots in your food. Microwave ovens can only “heat” the areas that the microwaves hit.

 
Hitting food with crazy waves seems kind of sketchy to me, so I wanted to figure out if it is safe to use or not. When looking up information on microwave ovens, it’s very confusing deciding which information is correct. On one hand, people say it’s bad and can cause cancer. On the other hand, people say it’s good and can help prevent cancer. It’s hard to make a decision when you have conflicting information. Here are just a few of the quotes I ran across during my research:

“While X-rays, gamma radiation, and even sunlight can cause cancer, microwave radiation cannot because it simply doesn’t pack enough power to damage your DNA.” - Gary Zeman of the Health Physics Society in McLean, Virginia

“I generally recommend that patients microwave their meats for 1-5
minutes and discard the juices before grilling.” [The juices are said to be linked to cancer]- Cyndi Thomson of the Arizona Cancer Center at the University of Arizona

“If you microwave your food you’re zapping away nutrients and risking your
health,” says physician Joseph Mercola, who recommends that consumers
get rid of their microwave ovens and eat at least a third of their food raw.

“Actually, microwaving retains more nutrients than other forms of cooking, if you don’t use a lot of water and don’t overcook the food.” - Barry Swanson, food scientist

“There is a tendency for most microwave users to cook everything on high power, except when defrosting. High is the default setting. The higher the power, the stronger the electric field, and the more damaging it is to nutrients. So, the lower the power, the safer [it is]. But only some microwave ovens are capable of true low power cooking. The microwave ovens equipped with inverter magnetrons actually reduce the power instead of just cycling it between high and off.” – John Andrews, naturalnews.com

“Cooking food destroys nutrients, whether it's on a stove, or in the microwave oven. But microwaving food on high power can be more destructive than cooking on the stove. So if you use a microwave, use one with an inverter magnetron, and cook on low power. Cooking on true low power (not intermittent high) will greatly reduce the amount of damage done to the food. Even on low power, I still don't know if a stove or microwave is worse. It's like asking me if I'd rather get beat by a club, or shocked by a taser.” John Andrews, naturalnews.com

The information on this topic is very conflicting. I even ran across an article about a little girl’s scientific experiment of microwave water verses boiled water that has been recycled all over the web and doesn’t show any true scenes of origin:

Ten Reasons to dispose of your microwave oven:
1.) Continually eating food processed from a microwave oven causes long term – permanent – brain damage by ‘shorting out’ electrical impulses in the brain [de-polarizing or de-magnetizing the brain tissue].
2). The human body cannot metabolize [break down] the unknown by-products created in microwaved food.
3). Male and female hormone production is shut down and/or altered by continually eating microwaved foods.
-Unknown Origin (many users)

Is this experiment real or not? Who knows? In the world of the Internet, anybody can post information about anything and claim that it’s true. Even Youtube was divided on the issue. After 3 hours of watching microwave videos both pro and con, I still can’t tell you if it’s safe to use or not. That’s pretty ridiculous! I can only tell you how it works and the side effects of cooking with a microwave oven. Since water evaporates when exposed to high energies, your food can be dried out or even taste funny from being cooked in microwaves. As far as it causing cancer, I don’t know. The official U.S. Department of Health website had no information on microwave use, but I wouldn’t be surprised if it did cause cancer. It seems like everything in America causes cancers these days. I guess we’re just forced to do what we think is right and see what happens afterwards.
