FoodFacts.com is always seeking new information that provides additional motivation for us all to stay committed to our healthy diet and lifestyle. Let’s face it, with so many processed foods and beverages surrounding us, as well as an enormous number of rather sedentary activity choices, we can all use a little extra inspiration from time to time! Today we read about a new study just published in the Journal of the National Cancer Institute that gives us plenty of encouragement for staying with our personal commitment to live the healthiest lifestyle we can.
According to this new research from the Division of Cancer Epidemiology and Genetics at the National Institutes of Health in Bethesda, Maryland, people who reported dietary intake that was the most consistent with the 2005 Dietary Guidelines for Americans had a lower risk of pancreatic cancer.
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.
Researchers 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.
Among the study participants there were 2,383 new cases of pancreatic cancer. Overall, the investigators observed a 15% lower risk of pancreatic cancer among participants with the highest HEI-2005 score compared to those with the lowest HEI-2005 score. This association was stronger among overweight or obese men compared to men of normal weight, but there was no difference for normal vs. overweight or obese women. While the authors adjusted for known risk factors such as smoking and diabetes status, they caution that other health factors not collected in the questionnaires may be associated with a more healthful diet and might explain some of the observed reduced risk. They also noted that diet is difficult to measure and the HEI-2005 was not designed specifically for the purpose of overall cancer prevention.
Researchers noted that the Dietary Guidelines for Americans are issued to promote overall health, including the maintenance of a healthy weight and disease prevention. Study findings support the hypothesis that a high-quality diet may also play a role in reducing pancreatic cancer risk. Future studies are needed to confirm these findings.
FoodFacts.com thinks that all of us who are committed to nutritional awareness and healthy habits should celebrate these findings, and others, that bring to light new benefits arising from our diligence. We encourage everyone in our community to spread the good news about the health benefits we can all repeat from that commitment!
