Abstract

The aim of this study was to investigate the effect of consuming small amounts of beer or a nonalcoholic beer taste beverage (non-beer) on gastric emptying and the polymorphisms in alcohol metabolism-related enzyme-encoding genes. Twenty male healthy volunteers were questioned regarding their alcohol consumption status,and body measurement was performed. The genetic polymorphisms in ADH1B (rs1229984,Arg47His) and ALDH2 (rs671 Glu487Lys) were analyzed. The subjects consumed 150 mL of beer or non-beer once per week,followed by the ingestion of 200 kcal of the test nutrient containing 13C-acetate 15 min later,after which the subjects’ exhalations were collected up to 120 min. The concentration peak of 13C was measured as Tmax. Diamine oxidase (DAO) activity for the marker of small intestinal function activity was also measured the day after the test. Gastric emptying was significantly slower in the group that consumed a small amount of beer,and in daily beer consumption group,and also in the ADH1B */*2,ALDH2 *1/*2 genotypes compared to non-beer drinking group. DAO values were not significantly changed between beer and non-beer group. The consumption of even a small amount of beer and the polymorphisms in ADH1B / ALDH2 affects gastric motility.
