Whey Protein May Protect Against Prostate Cancer

You, or someone you know, uses whey as a dietary supplement. Many associate the protein as a means of gaining muscle mass for pre- or post-workout meals. However, the cheese byproduct has other advantages than purely body-building.

Scientists of Ohio State University treated male human prostate cells with whey protein in vitro. The cells, in response, increased cellular production of the antioxidant glutathione by as much as 64 percent. Glutathione is one of several antioxidants known to control the production of cancer-causing free radicals. Whey contains the amino acid cysteine, a key element in the synthesis of glutathione.
