A new study suggested that consumption of high glycemic index (GI) or high carb diets may increase the risk of breast cancer in postmenopausal women, particularly those who've received hormone replacement therapy (HRT) and or were not involved in vigorous physical activity.
The study involved 50,000 Canadian Women who were enrolled in the National Breast Screening Study. Their dietary habits and other relevant information were surveyed between 1980 and 1985. During an average 16.6-year of follow-up, 1461 breast cancer cases were identified.
The researchers found that among the postmenopausal women, those used diets with highest quartile levels of glycemic index were 87 percent more likely to develop breast cancer compared to those using diets with the lowest quartile levels of glycemic index.
However, among the premenopausal women, those whose diets had the highest quartile levels of glycemic index were somehow 22 percent less likely to develop breast cancer compared to those who used diets with the lowest quartile levels of glycemic index.
The association of GI and the risk was slightly stronger among those postmenopausal women who were not involved vigorous physical activity and or had ever received HRT.
Glycemic index indicates how fast a food can raise the blood sugar. Cornflakes, cheerios, and puffed wheat are a few examples of foods with high glycemic index.
The study was conducted by Stephanie A. Navarro Silvera and colleagues from Albert Einstein College of Medicine in New York and University of Toronto In Toronto, Canada. The results were published in the April 20, 2005 issue of the International Journal of Cancer.
