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.

    Diet Plays a Role in Colon Cancer Reccurence: New Study

    By Posted on 2 Comments on Diet Plays a Role in Colon Cancer Reccurence: New Study

    It was only in the past few decades that research found diet plays a role in preventing colon cancer. Now, a study suggests that colon cancer patients whose diets are relatively low in starchy foods and carbohydrates have a lower risk of recurrence and death compared to those eating a high carb diet.

    The findings were published online yesterday in the Journal of the National Cancer Institute.

    The study builds on the authors’ earlier research that observed a link between an overall pattern of eating and recurrence among colon cancer patients. That study found patients who ate the most fats, meats, carbs and sugary desserts — a Western diet — were three times more likely to have their cancer recur compared to those whose diets were least Western.

    The current study focused on teasing apart which part of the Western diet might most contribute to the effect. Read more… “Diet Plays a Role in Colon Cancer Reccurence: New Study”
