High and Low Glycemic Index Mixed Meals and Blood Glucose in Youth with Type 2 Diabetes or Impaired Glucose Tolerance

This cross-over pilot study tested blood glucose response to low and high glycemic index meals in 12 obese youth with type 2 diabetes or impaired glucose tolerance. Participants demonstrated significantly lower mean daytime blood glucose and a trend toward lower variability, suggesting a clinically relevant impact of reducing glycemic index.
