High carbohydrate intake raises blood triglycerides, glucose, and insulin; reduces HDLs; and may increase risk of coronary heart disease (CHD). Epidemiological studies indicate that high dietary glycemic index (GI) and glycemic load (GL) are associated with increased CHD risk. The aim of this study was to determine whether dietary GI, GL, and available carbohydrates are associated with CHD risk in both sexes.
