PG - 706-10 AB - OBJECTIVES: Bedtime carbohydrate (CHO) intake in patients with type-2 diabetes may improve glucose tolerance at breakfast the next morning. We examined the 'overnight second-meal effect' of bedtime supplements containing 'rapid' or 'slow' CHOs. DESIGN: Randomized cross-over study with three test-periods, each consisting of two days on a standardized diet, followed by a breakfast tolerance test on the third morning. SETTING: The Lundberg Laboratory for Diabetes Research, Sahlgrenska University Hospital, Goteborg, Sweden. SUBJECTS: Sixteen patients with type 2 diabetes on oral agents and/or diet. INTERVENTIONS: Two different bedtime (22.00 h) CHO supplements (0.46 g available CHO/kg body weight) were compared to a starch-free placebo ('normal' food regimen). The CHOs were provided as uncooked cornstarch (slow-release CHOs) or white bread (rapid CHOs). RESULTS: On the mornings after different bedtime meals we found similar fasting glucose, insulin, free fatty acid and lactate levels. However, the glycaemic response after breakfast was 21% less after uncooked cornstarch compared to placebo ingestion at bedtime (406 +/- 46 vs 511 +/- 61 mmol min l(-1), P < 0.01). In contrast, it did not differ when the evening meal consisted of white bread (451 +/- 57 mmol min l(-1)) compared to placebo. According to an in vitro analysis, uncooked cornstarch contained approximately 4 times more slowly digestible starch as compared to white bread. CONCLUSIONS: A bedtime meal providing uncooked cornstarch improved breakfast tolerance the next morning while, in contrast, this was not found following a bedtime meal of white bread. The results are consistent, therefore, with the concept that an increased intake of slowly digestible carbohydrates exert an overnight second-meal effect in patients with type 2 diabetes.
