Food, not pills. Food, not pills.........I've said it before, so I'll say it again.
I still eat 5-7 servings/week of Brassica vegetables, some raw, some very lightly cooked (i.e. still crunchy). This is the season to really enjoy the wide variety of these delicious vegetables.
Let's see what have I eaten during this past week already: arugala, kale (of course), mustard greens, turnips, kohlrabi, broccoli, bok choy, daikon radish, and there are still two days still to go!
The Linus Pauling Institute has a great website that is always up to date with its information about Brassica vegetables.
I love food, not pills, just in case you did not catch my drift! :-)
Addendum (2.28.2012) - I just found the link to the actual PhD thesis from which the data for this research publication were derived. The important tidbit I gleaned from skimming through the thesis is that one serving/day of the cruciferous food consumed was enough, safe, and recommended to maintain a steady and effective level of anti-cancer molecules in the body.
Where kale is still more than decoration on my plate!
