Energy-dense foods are foods with a high proportion of energy relative to the food weight. Such foods are considered obesogenic. Hence, consumption of energy-dense foods, particularly those with a high content of unsaturated fats and sugar, predicts weight gain and greater waist circumference. This in turn increases the risk of obesity-related cancers such as breast, bowel, ovarian, endometrial, kidney, gallbladder, esophageal and pancreatic cancer.
Foods with a high dietary energy density (DED; kilocalories or kilojoules/gram of food or beverages consumed) may be associated with lower overall satiety (feeling of fullness), resulting in greater overall energy intake, whereas low energy-dense diets have been reported as resulting in weight loss and less hunger compared with dietary fat restriction in a year-long trial .
The association between energy-dense foods and the incidence of obesity-associated cancers has been further explored in an analysis of data from 92,295 postmenopausal women, aged between 50 and 79 years, who were enrolled in the Women’s Health Initiative (WHI) study in the US . DED was defined as the amount of energy (calories or kilojoules) per gram of food. Each woman’s DED was assessed by self-reporting, using a food frequency questionnaire at baseline. The incidence of obesity-related cancer was self-reported at baseline and follow-up, and re-confirmed during the 14.6 ± 5.6 years of follow-up using medical records.
