Dietary guidelines promote increased intake of fruits and vegetables, reduced consumption of meats, and the selection of whole grains over processed foods as ways to improve overall health and decrease cancer risk. Those recommendations are based on laboratory and epidemiology studies that suggest certain foods may trigger biological processes that help initiate cancers or create tumor-friendly environments. A new study by researchers at the University of Texas M. D. Anderson Cancer Center in Houston is the first to find a statistically significant association between measures of carbohydrate intake and lung cancer risk.

The March 2016 study in Cancer Epidemiology, Biomarkers, and Prevention (doi:10.1158/1055–9965.EPI-15–0765) investigated the relationship between two measures of carbohydrate intake—glycemic index and glycemic load—and lung cancer risk in non-Hispanic whites. Glycemic index scores measure the extent to which foods that contain equal amounts of carbohydrates increase glucose levels. Glycemic load takes into account both how many carbohydrates are eaten and the glycemic index of those foods. Previous studies looking at associations between glycemic index and glycemic load and cancer risk have had inconsistent findings.
