It is uncertain whether using microwaves to heat food alters its molecular structure or makes healthy food less healthy.

“Then secondarily, there's this question of whether using microwaves to heat the food, which is moving the water molecules in the food, changes the molecular structure. Is it making healthy food less healthy? I don't know. I mean, intuitively, I feel like it's probably not a great thing, but I haven't seen any real solid evidence to say that it's like toxic if you put it in the microwave.”
