It's not uncommon to see people microwaving leftovers in plastic dishes, heating up meals in the plastic containers they come in, or placing plastic wrap over foods to protect the inside of a microwave from splatters. Is all this as innocent as it seems?I don't think so. While plastic has many terrific uses, when it comes to cooking it should be avoided. DEHA [di-(2-ethylhexyl)adipate], sometimes found in cling wrap, and other chemicals commonly found in plastic are potential endocrine disrupters, and can negatively influence hormonal activity. While studies are underway to better define the health risks associated with plastics, it is best to steer clear of using plastic and plastic wrap in the microwave, as the heat can drive plastic molecules into your food. Instead, use glass or ceramic containers and cover foods with waxed paper or a paper towel. I also suggest avoiding pre-packaged foods that come in cling wrap (if you purchase such products, transfer these items to a different storage container once you get home).
