The use of microwaves to warm food does not pose any health risk, even during pregnancy, because the radiation is contained inside, not spreading.
In addition, the radiation is not in foods, because the heating happens by the movement of the particles of water and not by the absorption of the rays and, therefore, any type of food, like popcorn or baby food, can be prepared in the microwave .
The microwaves are built so that most of the radiation is contained inside and so even if some radiation can escape through the door or glass, it does not pass in sufficient quantity and is within the recommended levels international standards.
How to ensure that the microwave does not affect health
