Do foods high in glycemic index increase breast cancer risk?

By Posted on 1 Comment on Do foods high in glycemic index increase breast cancer risk?

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.

The Research

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.

    Low calorie-dense diets – think veggies – may lower breast cancer risk

    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.

    The study was published in The Journal of Nutrition.

    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.

    The study analyzed data from almost 57,000 postmenopausal women who had no history of breast cancer.

      Health Talk: Do eggs increase ovarian cancer risk?

      By Posted on 3 Comments on Health Talk: Do eggs increase ovarian cancer risk?

      Right now, the research does not show any strong link between eggs and ovarian cancer risk. There have been a few studies that have found a modest increased risk of ovarian cancer among women with the highest weekly egg consumption compared to those who don’t eat eggs. However, the studies that show a link are usually the study types more likely to have problems accurately estimating egg consumption and controlling for other potential influences on risk.

      And many studies examining this link have not adjusted for being overweight, which increases ovarian cancer risk. A recent analysis of the global research on eggs and ovarian cancer risk by the American Institute for Cancer Research found that current evidence is too limited to support any conclusion. More research is needed.

      Theoretically, high consumption of eggs’ cholesterol could lead to formation of compounds that pose risk. Yet it’s also possible that eggs’ rich content of choline (an essential nutrient) could play a role in maintaining healthy DNA to reduce cancer risk.
