I wish these people would do their research. Even briefly steaming or frying broccoli will cook out much of the cancer-fighting and anti-inflammatory goodness they skimmed over. Slow cooking is the worst of all. Wash the heads whole, in cold water, then cut to size and chew thoroughly. Otherwise you might as well take a damn multivitamin and eat whatever you want.
I have heard that cooking vegetables kills the nutrients, just like microwaves destroy all the water cells in whatever gets nuked. Instead of water wash your vegetables and fruits with vinegar. And multivitamins are the rocksalt version of the chemical, and most of the time the users body is not active or large enough to need a full vitamin.
Its better to take everything fresh from the source.
Huh, I'd never considered vinegar, but that's a great idea. I'll definitely give that a try. I don't even wash my home-grown crops (besides root crops), though anything store-bought has to be washed. I'm a firm believer that the native bacteria on a properly grown plant is good for you, but I might just be a hippie at heart. Still haven't gotten food poisoning (knock on wood).
Another thing many people don't consider is that munching on something like a broccoli stalk is actually going to clean your teeth to a degree. Its obviously no replacement for brushing morning and night, and will leave your teeth with all kinds of unsightly green bits, but my dentist theorizes that before we subsisted on processed sugars, a diet of raw veggies and roots was probably enough to keep teeth functioning well into adulthood.
Broccoli makes me toot.
