To the virtues of whole grains may now be added the possibility that they could lower the risk of pancreatic cancer, by as much as 40 per cent.
Dr. June M. Chan, of the University of California, San Francisco, and colleagues identified this reduced risk among adults who ate two or more servings of whole grains each day compared with those who ate less than one serving a day.They also noted about a 35 percent reduction in risk among individuals who ate the highest amount of fiber (26.5 grams per day or more) compared with those who ate the least (15.6 grams per day or less).
Eating a diet rich in a wide variety of grains is likely to not only help in the prevention of diabetes and heart disease, but also in a variety of cancers, especially the pancreatic.
The researchers looked at grain intake among 532 people with pancreatic cancer and 1,701 people without pancreatic cancer among the San Francisco Bay area population.
The two groups were similar in age, gender, and body weight, and had a similar history of diabetes, but those with pancreatic cancer were more frequently current smokers, the investigators note in the American Journal of Epidemiology.
Overall, the results of the study suggest that eating more whole grains may protect against pancreatic cancer.

"The risk reductions associated with some whole grain foods and fiber provide general support for the hypothesis that whole grains are better than more refined and sweetened grains for pancreatic cancer prevention," Chan said. However, "further studies are needed to confirm this," Chan added.
