The glycemic index of a food refers to its effect on raising blood glucose levels after consumption. Carbohydrates that are rapidly digested and absorbed tend to have a high glycemic index, because they release glucose quickly into the bloodstream. Foods with a high glycemic index create a rapid rise in blood sugar and a corresponding increase in insulin demand. Refined sugars, desserts, and sweet snack foods typically fall into this category.
Research published in the European Journal of Clinical Nutrition (e-published ahead of print June 1, 2011) examined dietary patterns in women with polycystic ovary syndrome (PCOS), with particular attention to glycemic index and macronutrient intake.
The study included 210 female participants. Among the subjects, 53% had a body mass index (BMI) greater than 25 kg/m². The researchers reported that 68% of women with PCOS consumed more than 35% of their total daily calories from fat. Higher body weight and dietary patterns characterized by greater fat intake were common among women with PCOS in the study population.
The authors analyzed dietary composition in relation to metabolic and reproductive features of polycystic ovary syndrome, noting that both body weight and carbohydrate quality were relevant factors in the dietary profiles observed.
