2. Go for the grain
Opt for two or more servings of whole-grain breads, cereals, and pastas and you could slash your risk of developing pancreatic cancer by a whopping 40 percent. In premenopausal women, the fiber in whole-grain cereals was shown to cut the risk of developing breast cancer in half. Research also shows the fiber in whole grains can modestly reduce your risk of developing colorectal cancer.
