Diets high in fruits, vegetables and other foods with fewer calories per bite may lower an older women’s risk of breast cancer compared to women who eat lots of high calorie-dense foods, suggests a new study. The findings suggest the link is independent of overweight and obesity, a risk factor for postmenopausal breast cancer.
In this study researchers looked at energy density, the amount of calories in a certain weight of food, typically a gram. Cakes, ice cream and other foods heavy in oils and added sugars are high in energy density. Low energy-dense foods are higher in water and fiber, making these foods generally lower in calories for every gram. Vegetables, fruits and many unprocessed grains are generally low in energy-density.
At the same time that global warming is making news, a study suggests that eating more fruits, vegetables and nuts and less meat and alcohol — with fewer calories — can reduce greenhouse gas emission by almost 20 percent, compared to the average diet. Many of the dietary patterns identified as environmentally healthy align with AICR’s recommendations for cancer prevention.
