Overview
Brief Summary
Moderate alcohol consumption is associated with a decreased risk of type II diabetes mellitus. In a recent study of Greenfield et al. it was observed that moderate alcohol consumption significantly improved postprandial glucose concentrations. Similar observations were made in our previous study. One of the mechanisms by which this may occur is delayed gastric emptying after alcohol consumption.
Detailed Description
Purpose: The primary objective of this study is to investigate the effect of moderate daily alcohol consumption on hepatic glucose uptake and peripheral glucose storage. Secondly, the effect of moderate alcohol consumption on gastric emptying and postprandial wellness will be studied. These effects will be studied in apparently healthy, lean or overweight young men.
Design: Randomized, partially diet-controlled, placebo controlled cross-over design.
Subjects: Healthy male lean and obese volunteers aged between 18 and 40 years (n=18).
Intervention: During 2 periods of 21 days either white wine or white grape juice has to be consumed with the evening meal. The last 7 days of each period will be fully dietary controlled.
Treatment A: 375 ml of white wine (35 g alcohol) per day Treatment B: 375 ml of white grape juice per day
Measures:
- Glucose metabolism: glucose uptake and peripheral glucose storage (measurement of isotopic enriched plasma glucose levels.
- Gastric emptying and postprandial wellness.
- Postprandial glycemic response and related factors (glucose, insulin, lactate, FFA, glucagon, ghrelin, CCK, GIP, GLP-1, PYY, triglycerides, total cholesterol, HDL cholesterol, LDL cholesterol, paracetamol (absorption test)
