How Microwave Ovens Work
Microwave ovens convert electricity into microwaves--a type of electromagnetic radiation--that are reflected inside the ovens' metal interior, and are absorbed by food. The microwaves cause water in the food to vibrate, which produces the heat that cooks the food.
Contrary to the belief that microwaves cook from the inside out, they actually heat the outer layers, which transfer heat to the inner portions. Most of us know from experience that microwaved foods are not cooked evenly. Cold and hot pockets are a hallmark of microwave ovens.
Microwave Oven Safety Concerns
Radiation emissions have been a big concern for consumers. However, the
Compared with other types of cooking, microwaves use less energy and have been shown in some studies to retain food nutrients better. As long as foods are adequately cooked, warmed, or cooled enough before they're consumed, food safety is a non-issue. So, continue to enjoy the convenience of this 20th century timesaver, but do so wisely and safely.

2. Don't heat food or liquids in plastics. Avoid toxins in plastics by removing frozen meals from plastic containers and replacing plastic wraps with a glass lid or waxed paper.
3. Heat liquids only to boiling to avoid scalding by an overheating explosion.
