Microwave ovens have been in widespread use since the 1980s, and today almost every American home has one. Many of us happily use it daily, whether to warm up leftovers or boil a cup of water, without a second thought. But there are some health-conscious people out there who believe that microwave ovens are a health hazard, and/or that they destroy the nutrients in our food. Should we be concerned?
The short answer is no—with one caveat. According to Harvard Medical School, microwaves cook or heat food using waves of energy that are similar to radio waves. These waves primarily affect water molecules in the food, by causing them to vibrate and quickly build up heat as a result. There is no evidence that these types of waves harm our bodies in any way.
And microwaving our food is actually one of the best ways to preserve nutrients. When it comes to nutrient preservation, the faster the cooking method the better, and as we all know, the microwave tends to win the speed contest.
One thing we do need to be vigilant about is microwaving food in plastic. When many types of plastic are heated, either bisphenol-A (BPA) or phthalates can leach out of the plastic into the food—not a good situation. Both substances can mimic human hormones and are considered endocrine disruptors, which may produce adverse developmental, reproductive, neurological, and immune effects in humans.
So as long as you’re careful about what containers you use to heat up your foods, you’re good to go!
