Of course there will be "mythbusters" paid for by the food industry who has a food product line to protect. They will try and down play the facts, we've seen it before. They'll hope people forget the truth.
Yes, cooking can destroy vits and nutrients but cooking in a conventional oven is the opposite of cooking in a micro. with the outcome hoping to be the same. ... but it never is.
A micro cooks from the INSIDE of the food with the heat working it's way out. A conventional oven or stove top cooks from the OUTSIDE working the heat in. That's why micros leave food rubbery. They blast the inside and the outside stays more firm.
Whereas conventional cooking can brown food and potentially leave the inside uncooked or under cooked. No MV browns food.
With conventional you have more control because as soon as one removes the heat source, the product stops cooking.
With MV there so much heat INSIDE that it really can be dangerous, like the exploding potato, hotdog, or any other MV'd food item that's been in for too long.
With food, the nutrients are INSIDE because once a food surface is exposed to air the nutrients start degrading so the last place anyone should apply heat is to the INSIDE of the food.
It's like sauteeing a stir-fry. Throw the veg into the wok, shuffle them around for a minute or so to get the outsides seered and eat up for a nutritious meal.
VS.
rubbery veg that was in the MV, in a plastic coated box and now have ZERO nutritional value (and probably lots of salt to make it palatable)
