In a recent study published in The Journal of Nutrition , researchers examined the effects of low- and high-glycemic-index (GI) Mediterranean-style (MED) healthy eating patterns (HEPs) on sleep and health-related quality of life (HRQoL). Study: Low- vs high-glycemic index Mediterranean-style eating patterns improved some domains of health-related quality of life but not sleep in adults at risk for type 2 diabetes: The MEDGICarb randomized controlled trial .

Evidence suggests associations between low HRQoL and higher cardiometabolic risks. The 36-item short-form health survey (SF-36) is commonly used to measure HRQoL. Sleep is an important lifestyle factor related to cardiometabolic health and HRQoL.
Various studies have reported associations between adherence to HEPs and subjective measures of well-being and health. Several studies have demonstrated associations between MED-HEP adherence and improved sleep and HRQoL; however, most studies have been cross-sectional, warranting more robust intervention studies. The GI of food represents its carbohydrate quality, and glycemic variability is a marker of blood glucose fluctuations.
Previously, the authors reported that the GI of a MED-HEP is a determinant of glycemic variability and postprandial glucose response. To date, no intervention study has investig.
