Eating foods with a high glycemic index (GI) can make your blood sugar rise higher and faster after eating. Theoretically, that could cause unhealthy levels of hormones like insulin, which seem to promote development of some cancers, including breast.
However, research suggests that glycemic index by itself has little to no relation to breast cancer risk.
An analysis of 19 studies found no link between breast cancer risk and diets high in GI beyond what could occur by chance. Even glycemic load (GL), which takes portion size of foods into account, showed no significant link to breast cancer risk. The links were not consistent and could reflect other qualities of those diets. Another analysis that included only studies with a stronger design that follows people over time (called prospective cohort studies) found a weak five to six percent increase in breast cancer risk when comparing diets at the very highest to the very lowest glycemic index or glycemic load, respectively.

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.
Research shows that drinking alcohol increases cancer risk. Now, a new study is suggesting that going for that daily run or walk might offset risk for cancer mortality.
This study, published in the British Journal of Sports Medicine, found the link between alcohol and cancer mortality goes away when people meet the minimum physical activity guidelines. These findings have been making headlines, but do they give you license to drink with abandon as long as you’re physically active? Not so fast.
The study used data from over 36,000 British men and women ages 40 and up who were interviewed between 1994 and 2006 about their physical activity and alcohol consumption habits as part of larger, ongoing health surveys. Researchers classified participants as never-drinkers, ex-drinkers, or current drinkers based on what they told interviewers. Current drinkers were further categorized by how much alcohol they drank in the past week. Read more… “Can Exercise Offset Alcohol-Related Cancer Death?”
