1. Cooking or heating food in a microwave oven will destroy the nutrition of food and greatly reduce the nutrition of food, because electromagnetic radiation changes and destroys the molecular structure of food.

2. Food cooked by microwave will produce toxic and carcinogenic additives. Because proline in food becomes hydrocarbyl proline after microwave irradiation, it is a carcinogen.

Microwave is an electromagnetic wave that can pass through glass, paper, plastic and similar materials. The electromagnetic tube in the microwave oven emits microwave, which is reflected back and forth in the microwave oven and absorbed by the food, so that the water molecules in the food vibrate, thus generating heat and heating the food. But microwave will reflect when it meets metal, which is also forging.
