OBJECTIVE The purpose of this study was to quantify the effects of glycemic index on postprandial glucose excursion (PPGE) in children with type 1 diabetes receiving multiple daily injections and to determine optimal insulin therapy for a low-glycemic index meal. RESEARCH DESIGN AND METHODS Twenty subjects consumed test breakfasts with equal macronutrient contents on 4 consecutive days; high-...

Acne vulgaris may be improved by dietary factors that increase insulin sensitivity. We hypothesized that a low-glycemic index diet would improve facial acne severity and insulin sensitivity. Fifty-eight adolescent males (mean age ± standard deviation 16.5 ± 1.0 y and body mass index 23.1 ± 3.5 kg/m(2)) were alternately allocated to high or low glycemic index diets. Severity of inflammatory lesi...

Previous studies have provided limited evidence for a harmful effect of high glycemic index and dietary glycemic load on cancer. The authors analyzed associations among glycemic index, glycemic load, and risk of cancer in women and men in the National Institutes of Health-AARP Diet and Health Study. Published glycemic index values were assigned to 225 foods/food groups. Glycemic load was calcul...

BACKGROUND Dietary glycemic index, an indicator of the ability of the carbohydrate to raise blood glucose levels, and glycemic load, the product of glycemic index and carbohydrate intake, have been positively related to risk of coronary heart disease. However, the relationships between glycemic index and glycemic load and high-density lipoprotein cholesterol (HDL-C) concentration in the US popu...

BACKGROUND Previous epidemiological investigations of associations between dietary glycemic intake and insulin resistance have used average daily measures of glycemic index (GI) and glycemic load (GL). We explored multiple and novel measures of dietary glycemic intake to determine which was most predictive of an association with insulin resistance. METHODS Usual dietary intakes were assessed ...

Earlier this year, I enjoyed an opportunity to speak at the Swiss Forum for Sport Nutrition in Zurich, organized by Dr. Paolo Colombani. One of my fellow presenters at this forum was Samuel Mettler, a graduate of the Movement Sciences and Sport course at the Swiss Federal Institute of Technology (ETH Zurich). Samuel is about to finish his doctoral thesis on the glycemic index in sport and the i...
