Do microwave ovens decrease the nutritional content of food?

My family uses microwave ovens a lot, and I was wondering if cooking foods such as broccoli in a microwave can really diminish the antioxidants in the food. I came across a web site that said there was a study published in a science journal that showed that broccoli lost 97 percent of its antioxidants after being cooked in a microwave. I'm not sure whether to believe this or not. Could you help me out?


How do I use dental dams?

I've seen the recommendations. I've seen the suggestions for do-it-yourself workaround (cutting open a condom, plastic wrap... ). What I *haven't* seen is practical usage advice — how to place the thing effectively, how to overcome the limitations of losing direct contact, how to arrange things to permit vaginal penetration with fingers while still maintaining protection and so on. Best-practice condom use isn't perfectly obvious either, but at the most basic level it's pretty straightforward. If you want to build acceptance for barrier use during cunnilingus, it needs to be at least as clear and/or at least as well-documented.


Can I drink chlorophyll?

A coworker of mine was drinking a green liquid at the office and told me that it was "chlorophyll water". Neither of us are sure what the health benefits of ingesting chlorophyll are, and it's hard to find reliable info on the internet. Is this fad based in medical fact, or is it just a weird new drink to try?
