Beer has been related to gastroesophageal reflux (GER) and dyspepsia, based on its alcohol and gas content. A study evaluated the association between moderate consumption of traditional and alcohol-free beer and upper digestive symptoms, gastric accommodation and GER.
The study included healthy adults without frequent gastrointestinal symptoms and GER. The intervention involved administration of traditional beer to 10 subjects (substudy 1) and alcohol-free beer to 20 (substudy 2); control intervention entailed administration of water. The study duration was 2 weeks.
Postprandial gastric accommodation was assessed through the maximum tolerated volume during a nutrient drink test after the ingestion of water (day 1) and beer (day 8), in which symptoms of dyspepsia were evaluated every 5 minutes. An impedance-pH monitoring assessed 24 hours and post-NDT GER (days 1 and 8). Symptoms were evaluated daily during the study. The defined variables were compared between visits and weeks using a nonparametric test for paired data.
Dyspepsia symptoms showed a progressive increase during the NDT for both interventions in the 2 substudies, though no significant differences were detected in the MTV analysis. No differences were detected in the sum of weekly symptoms. The analysis of impedance-pH monitoring did not show any differences between intervention and control visits for both interventions.
Moderate consumption of traditional and alcoholfree beer does not increase dyspeptic symptoms or GER in healthy subjects, whether in a controlledintake or real-life situation, the authors conclude. Neither gastric accommodation nor reflux episodes are modified in this context.
