I don't see that microwaves will destroy more goodness that traditional cooking. I have occasionally used it to cook vegetables and they cook more quickly than if you boil them.

Having said that, I only use ours to cook porridge, custard, white sauces, and to reheat portions of cooked food that I've had in the freezer. It's particularly good at those tasks.

The article I read was fairly alarmist, but I can't find it again. :(

The effects on nutrition are minimal, according to most sources. What you put in your mouth is more important than how you heat it up.

There are some sources that claim the microwaves will make your food toxic. They also are against vaccines, say that aircraft condensation trails are mind-altering nerve agents, and claims that Microsoft deliberately destroyed an essay they were writing.

Thanks.

WE're having a debate now about whether to reinstate the microwave. I'm pretty much convinced that there isn't really a health issue- so it comes down to whether we need to clutter up the kitchen with a large piece of kit that we barely use- but which comes in handy every now and then.

Ah, yeah, for heating water for drinks or drinks that have gone cold (for such short stuff), it works fine. Also for meals that had been properly cooked before. Or for helping defrosting stuff a little.
But, other than that, nothing gets close to the effect of a real oven or a stove. Simply, it just takes way too much water out of the thing you're trying to heat up. Quickly turns everything into shoe soles. Or doesn't really get through to the core with that kind of heat it produces.
With normal means to cook - no problem.
I think, the stuff you heated up in it also tends to get cold again too quickly, at least for meals and food. Don't have that effect with stuff prepared on a stove at least.

It's been a long time since we did any serious cooking in the microwave. And now we won't be doing any.
