- Postprandial glucose is a major determinant of A1C that to specifically improve PPG have the ability to improve A1C. Activating oxidative stress
- Blood sugars are affected at any given moment by -basal insulin -Food -Boluses and corrections -activity -Stress and illness Carbohydrate amount is considered the most important dietary determinant of postprandial glucose control: ADA position paper 2006
- Glycaemic index for meal planning has not been endorsed by the ADA. However base on experience, people can develop their own “personal glycaemic index”. Whilst some evidence that following a lower Gi meal can have a small but clinically sig effect on glycaemic contro Fat delays peak glycaemic response Sugar alcohols: (average 2 cals per gram) recommended if >10g per serve, divide by 2 and count it. Sorbitol, Xylitol, Mannitol, Maltitol Study showed that addition of extra protein showed a greater glucose response and insulin req Peters AL, Davidson MB.

- Testing using 50g CHO Glycaemic load – validated in glycaemic response and insulin demand in healthy adults, whether it can be employed as a predictor of exogenous insulin req, not examined. Low GL may not necessarily offer the glycaemic benefits of a low GI diet
- Carbohydrate amount is considered the most important dietary determinant of postprandial glucose control: ADA position paper 2006 Second meal effect of GI Meta analysis low Gi 0.5% than those produced by high GI diets, small but clinically useful second article: PPGE lower with low GI and pre-prandial insulin better than post Low GI diet JADA had more fibre les fat and no diff in energy (education and food lists given), sig lower mean BSL on day they consumed low GI Adolescents with diabetes consume fewer calories from CHO and more from fat (esp boys, more sat fat) than those without diabetes: Diabetes Care 2006
- Pizza Study 50:50 over 8 hours Cross-sectional study 499 records Lowest HBA1C’s were found in the group using 1 or more alternate boluses per day
- Meals had equal macronutrient ( CHO ~60g) calories and fibre, only GI varied, n=20 Randomised to either standard or Dual wave 50:50 2 hours Consumed either low or high 2 consecutive days CGMS used to monitor A DW bolus before low GI meal decreased PPG are under curve by 47% and lowered risk for hypoglycaemia for the same premeal glucose compared to std bolus. High GI meals resulted in SIG upward trend regardless of bolus type 11 hypos’ seen in low GI group (7 with std bolus, 4 with dual wave bolus). Those with lower pre-meal BSL’s more likely to go low using a std bolus than a dual wave
