Wondering if my title is true or not. I am trying to save money and also eat healthier. Its hard when your only feeding yourself to stock up without anything going bad.

I know when you use the microwave that takes nutrients away but what about when dethawed and cooked again?

I love beef stir fry but i only use half of the ingredents and the other half goes bad. ( snow pees, etc) I don't tink you can freeze stir fry either. When i freeze foods in old butter containers , even after a week a layer of frost is on top. I know thats not good

looked up a few answer/ sites for your question.

Microwaving food may destroy some nutrients.

One that is really harmed is folic acid.

This article discusses the loss of nutrients during blanching and microwaving. This article is about FRESH cooking.

REheating previously cooked food would damage more nutrients further.

I'd use a good Vitamin supplement if you reheat frozen food alot ..like Centrum.

This article goes into more detail for other veggies:

Sure, when you cook food--either microwave or regular--you'll take out anything vulnerable to heat. That's why fresh food is so important.

But if it's been cooked once, and you're not re-heating in water and tossing the water out, then you won't do much more than has already been done. Basically, cooking is a chemical reaction that's triggered by heat; and your cooked food has already had that chemical reaction happen--it won't go any further unless you actually burn it.

Actually, that's not necessarily true. It depends on what heat at which it was cooked the first time and the second time (microwaving is the worst). For instance - if it was cooked over low heat and contains unrefined polyunsaturated or monounsaturated fat, and then it is reheated over high heat - you risk oxidizing those fats.

Fresh food is really the way to go. If you *have* to use frozen food, re-heat it at the lowest heat you have patience for.
