Why does microwave heat up food?
Heating your food in the microwave can strip away its original nutrients. What may have started as a nutritious plate of food has now evolved into “dead food” due to the dielectric heating of microwaves. “They bounce around the inside of your [microwave] oven and are absorbed by the food you put in it,” writes Dr. Joseph M. Mercola, licensed physician and surgeon. The water molecules rotate rapidly in the microwave and in the food in high frequencies which creates molecular friction and heats up your food. This causes the molecular structure in your food to change, and as a result diminishes the nutrient content in the food.
What happens if you put plastic in the microwave?
When you head foods that are wrapped in plastic in the microwave, you can create carcinogens in the food. Based on Russian research and German studies, the Russian government issued a warning about the health hazards microwave ovens can have on the human body and the environment. The assembling of microwavable foods are found to contain toxic chemicals such as BPA, polyethylene terpthalate (PET), benzene, toluene, and xylene says Foodbabe.com. The plastic containers used to heat these microwave meals have been found to release the carcinogens along with other harmful toxins into your food which is then absorbed by your body.

How does microwave radiation affect the body?
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. Additionally, the lens of the eye is particularly sensitive to intense heat, and exposure to high levels of microwaves can cause cataracts. But these types of injuries – burns and cataracts – can only be caused by exposure to large amounts of microwave radiation.
