Consuming a high quality diet is associated with lower risk of pancreatic cancer

Extract

People who reported dietary intake that was most consistent with the 2005 Dietary Guidelines for Americans had lower risk of pancreatic cancer, according to a new study published August 15 in the Journal of the National Cancer Institute .

Previous studies investigating the relationship between food and nutrient intake and pancreatic cancer have yielded inconsistent results. The U.S. Government issues evidence-based dietary guidelines that provide the basis for federal nutrition policy and education activities to promote overall health for Americans. The authors evaluated how closely study participants’ diets matched the 2005 Dietary Guidelines for Americans, as measured by the Healthy Eating Index (HEI-2005), and then compared their risk of pancreatic cancer.

Hannah Arem, Ph.D., from the Division of Cancer Epidemiology and Genetics at the National Institutes of Health in Bethesda, MD, and colleagues calculated HEI-2005 scores for 537,218 participants in the NIH-AARP Diet and Health Study (ages 50–71 years), based on responses to food frequency questionnaires. Pancreatic cancer risk was then compared between those with high and low HEI-2005 scores, accounting for the influence of other known pancreatic cancer risk factors.
