Some claim that using microwaves is unhealthy, that these cooking contraptions are capable of killing the nutrients in our food and reversing the benefits of beverages like tea. This doctor -- the well-known Dr. Katz -- says microwaving may actually be the least damaging to nutrients. Microwaves ovens are not unhealthy, he says. They are, in fact, a very nutritious way to cook.

Microwaves allow for quick cooking and in most cases, the less time a food is exposed to heat, the higher its nutrient levels. As for tea, all you're doing is heating the water and adding the tea bag later. There's just no way nutrient levels can be adversely affected in this case.

The only argument Dr. Katz can identify against microwave cooking is this: It can leave food a bit dry or perhaps with a different taste. But it won't leave your diet any less nutritious.
