Shikany JM et al. – Overall, there were no associations of baseline carbohydrate, glycemic index (GI), or glycemic load (GL) with incident prostate cancer in minimally or fully adjusted models. There were no associations when the 228 advanced and 2,208 non–advanced cancers were analyzed separately. Dietary carbohydrate, GI, and GL were not associated with incident prostate cancer in Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial (PLCO). The narrow range of GI in this cohort may have limited the ability to detect associations, an issue that future studies should address.
