Microwaves are a safe, effective, and highly convenient cooking method. There is no evidence that they cause harm — and some evidence that they are even better than other cooking methods at preserving nutrients and preventing the formation of harmful compounds.
What are 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.12-Dec-2017

Are microwaves positive or negative?
The microwaves create an electric field that oscillates rapidly back and forth inside the oven. Water molecules in the food, because they are polar (one side is positively charged and the other side is negatively charged), rotate back and forth to align with the changing field. This motion causes the food to get hot.

What happens when you microwave food?
This creates heat, but it also damages or destroys the food’s amino acids. When heating food, microwaves can cause: Transformations that create carcinogens. A reduction in the bio-compatibility of nutrients (vitamins and minerals) The loss of between 60% to 90% of caloric energy. A decrease in protein content.
How does a microwave work?
They use a form of electromagnetic energy, using longwave radiation like radio waves. Each microwave contains a magnetron, which is a tube where radiation at about 2,450 MHz interacts with the molecules in food.
Why do people reheat food in the microwave?
If you reheat or cook food in the microwave every day, it can lead to permanent, long-term damage. This is due to the transformation of food nutrients. The human body can’t break down unknown substances. The same goes for food that the microwave alters.
What happens if you don't eat enough food?
This causes memory loss, emotional instability, and a lack of concentration. Lower or alter the number of nutrients, minerals, and vitamins in food to levels so low it’s as if we hadn’t eaten it at all. Destroy up to 75% of food’s natural antioxidants.

Why do you microwave broccoli?
Using a microwave oven can prevent the loss of important vitamins and minerals in your food. Vitamin C and potassium are often lost in liquid used to boil food. Cooking broccoli in your microwave oven may prevent the loss of glucosinolate, a compound in broccoli which may be responsible for its cancer-fighting properties, and which is lost in boiling. Since proteins don't brown in the microwave oven, fewer nutrients, such as vitamins A and E, are likely to be destroyed by oxidation.
