Gill or be killed
Shark cartilage won't ward off cancer, but a shark's diet might. A recently completed 12-year Harvard study of nearly 48,000 men determined that those who ate fish more than three times a week were 40 percent less likely to develop advanced prostate cancer than those who hit the surf only twice a month.
It's those amazing omega-3s again, though they don't deserve all the credit. "Fish also contains vitamin A and vitamin D, which may help prevent prostate cancer," says Michael F. Leitzmann, M.D., a coauthor of the study.
That's why it may be better to skip supplements and stick with actual fish. Salmon, mackerel, and herring have the best balance of omega-3s, vitamin A, and vitamin D.
Note: Don't wait until the weekend to go fishing, says Dr. Leitzmann. "Space your fish consumption out over the week so you consume a steady supply of these compounds."
