Find your whey

Not since lycopene landed in our lives has there been a more promising prostate-cancer-fighting nutrient than whey protein. In a recent Ohio State University study, researchers treated human prostate cells with whey protein and then measured the cells' levels of a natural cancer-blocking compound called glutathione.
The finding: Glutathione levels rose by a remarkable 64 percent. "Whey is a great source of the amino acid cysteine, and cysteine can become glutathione in the body," explains Rosemary L. Walzem, R.D., Ph.D., director of the Center for Nutrition, Health, and Food Genomics at Texas A&M University.
One of the best sources of whey is yogurt; a lot of the protein is in the clear liquid on top, so don't pour it off. You can also pick up powdered whey-protein isolate—vanilla-flavored—and add it to instant oatmeal.
