It rubs me the wrong way to watch people microwave food in in plastic containers, plastic bags or Styrofoam. It’s like you can just feel the chemicals cooking! I used microwave in plastic too, but my dad saw me doing it one day and stopped me. Now I tell other people same thing, even if it pisses them off because they’re hungry. When you microwave your food in plastic not labeled microwave-safe, you may be allowing toxins into your food, increasing the levels of carcinogens you consume. Watch out for rubber lids and their containers too! Freezer bags aren’t innocent either along with meat trays, foam containers, coated cardboard, and most soup and noodle cups. A lot of people microwave food with Saran Wrap on top of it. All of this is bad for you!!
It may be time for you to ditch the plastics and learn about other ways you can store and heat up food.
