In fact, the study revealed that the increased risk appeared limited to women who were of a normal weight at enrollment in the program. The team found that women who consumed a diet higher in DED were 10% more likely to develop an obesity-related cancer, independent of body mass index. In order to gain a better understanding of how DED alone relates to cancer risk, researchers used data on 90,000 postmenopausal women from the Women's Health Initiative including their diet and any diagnosis of cancer. Previous studies have shown that regular consumption of foods high in DED contributes to weight gain in adults. Processed foods, like hamburgers and pizza, are considered high-DED foods because you need a larger amount to get necessary nutrients. Whole foods, including vegetables, fruits, lean protein, and beans are considered low-DED foods because they provide a lot of nutrients using very few calories. The more calories per gram of weight a food has, the higher its DED. Their findings are published in the Journal of the Academy of Nutrition and Dietetics.ĭED is a measure of food quality and the relationship of calories to nutrients. To find out, researchers looked at DED in the diets of post-menopausal women and discovered that consuming high DED foods was tied to a 10% increase in obesity-related cancer among normal weight women. While there is a proven link between obesity and certain types of cancer, less is known about how the ratio of energy to food weight, otherwise known as dietary energy density (DED), contributes to cancer risk. Current research shows that an estimated 30% of cancers could be prevented through nutritional modifications. Philadelphia, PA, AugDiet is believed to play a role in cancer risk.
