At PCC we often get calls from individuals asking if microwave ovens affect the nutritional value of food. The answer is that there's much we do not know, but the research we have raises concern.
The U.S. Food and Drug Administration's (FDA) failure to review any of the research conducted on microwaved food since 1968 also raises questions.
A radiation expert at the FDA's Center for Food Safety and Applied Nutrition told PCC that the FDA made its decision in 1968 that microwaved food was safe. He said the FDA never has conducted any research of its own and that the FDA has not reviewed any of the studies conducted at Stanford University or research published by the Lancet, Pediatrics, and the Journal of Natural Sciences.
For a review of the scant research that has been, see the story, Microwaved food: is it healthy?.
