Gastric emptying of beer in Mexican-Americans compared with non-Hispanic whites.
Gastric emptying studies were performed on 11 nondiabetic Mexican-Americans and 11 nondiabetic non-Hispanic whites following ingestion of 450 mL beer. Plasma glucose, serum insulin, and serum alcohol levels were measured in the fasting state and at 7, 15, 30, 45, and 60 minutes following ingestion of the beer. The area under the gastric emptying curve was significantly larger for non-Hispanic whites compared with Mexican-Americans (P = .0492), indicating that Mexican-Americans had faster stomach emptying. Partial correlation coefficients (adjusted for ethnicity, gender, age, and body mass index [BMI]) showed the gastric half-emptying time was inversely related to the incremental levels of glucose (r = -.709, P = .0010) and alcohol (r = -.650, P = .0035). The faster the rate of gastric emptying of beer, the higher the glucose and alcohol levels. There were no significant correlations between insulin and the rate of gastric emptying. The caloric emptying rate for the beer was much more rapid than previously reported for other liquid meals.
