Higher Intake of Quality Carbohydrates Associated With Reduced Risk of Breast Cancer
The Carbohydrate Quality Index (CQI) classifies dietary intake of carbohydrates based on four criteria: dietary fiber, ratio of solid carbohydrates to total carbohydrates, glycemic index, and ratio of whole grains to total grains. A recent study has found that women with a higher CQI may have a reduced risk of breast cancer.
Participants in the study included 461 women diagnosed with breast cancer and 495 women without breast cancer. Food frequency questionnaires were used to calculate the CGI for each participant.
Participants with the highest CQI were found to have a lower risk of breast cancer compared to those with the lowest CQI. In addition, premenopausal women with the highest glycemic index scores were 1.85 times more likely to have breast cancer compared to those with the lowest glycemic index scores.
The study was conducted by researchers from Shahid Sadoughi University of Medical Sciences. It was published online ahead of print on November 26, 2021 in the Nutrition Journal.
