Eat your veggies

And fruit, too. The fresh ones, with bright colors are best. I didn't know this, however:

But the superstars seem to be cruciferous vegetables: broccoli, Brussels sprouts, cabbage, cauliflower, arugula, kale, kohlrabi, mustard, rutabaga, turnips, bok choy, horseradish, wasabi and watercress.

These vegetables contain potent substances that seem to protect against cancer and appear to have antimicrobial activity. In April, scientists reported that substances extracted from broccoli and other cruciferous vegetables thwarted (in the laboratory, at least) the bacteria that cause stomach ulcers as well as 23 of 28 other common microbes and fungi. There's also evidence that eating cruciferous vegetables may help counteract the suspected cancer-causing chemicals found in grilled food.
