Microwave Safety
I reheat many foods in the microwave. Is there any harm in eating microwaved foods every day? —E.S., Bayou Cane, Louisiana
Current research suggests that cooking food in the microwave is not harmful. In fact, using a microwave to cook foods preserves more of their vitamins and minerals, since their exposure to heat and water is shorter than with conventional cooking methods. (But don't forget to use microwave-safe dishes when cooking or reheating foods.)
