Thread: Reheating food in the microwave -- effects on nutrients?

I've always read that cooking food from raw in a microwave will kill some of the nutrients. What about reheating food?

I cook all my food without a microwave, but at work I have to reheat food for meals that I made the night before. Is this killing any of my nutrients?

lol, ya but in this day and age you get crap in your body from just about everything. Walk outside and you breah car exhaust and second hand smoke all day. Even healthy food has to come in packages.

I buy all organic food. I eat nothing but whole foods. And even when I do package meals for work in tupperware it's not for very long.

Beef roasts microwaved at "simmer" were comparable with conventionally cooked roasts in sensory quality, while vegetables cooked by an institutional (1,150 w) microwave oven were superior to those cooked in a domestic (550 w) microwave oven. Microwave-cooked bacon had lower levels of nitrosamines than conventionally cooked bacon; however, the use of a new alpha-tocopherol coating system has been found to be a safe N-nitrosamine inhibitor regardless of cooking method used."

Granted, it doesn't specify what the "normal" nutrient retention is.

Thanks for the link. I'll have to look in to how new my work's microwave is. I imagine it's pretty modern. It's provincial government. They're overwhelmingly on top of work health and safety. We're a ministry of about 180 people and we have an ergonomics department, lol. When I started they came to me to see if my chair and keyboard were postioned in a safe way for my spine. Talk about service!
