Gut microbiota modulation might constitute a mechanism mediating the effects of beer on health. In this randomized, double-blinded, two-arm parallel trial, 22 healthy men were recruited to drink 330 mL of nonalcoholic beer (0.0% v/v) or alcoholic beer (5.2% v/v) daily during a 4-week follow-up period. Blood and faecal samples were collected before and after the intervention period. Gut microbiota was analyzed by 16S rRNA gene sequencing. Drinking nonalcoholic or alcoholic beer daily for 4 weeks did not increase body weight and body fat mass and did not changed significantly serum cardiometabolic biomarkers. Nonalcoholic and alcoholic beer increased gut microbiota diversity which has been associated with positive health outcomes and tended to increase faecal alkaline phosphatase activity, a marker of intestinal barrier function. These results suggest the effects of beer on gut microbiota modulation are independent of alcohol and may be mediated by beer polyphenols.
肠道微生物群调节可能是介导啤酒对健康影响的机制之一。在这项随机、双盲、双臂平行试验中,招募了 22 名健康男性,在为期 4 周的随访期间,每天饮用 330 毫升无酒精啤酒(0.0%v/v)或酒精啤酒(5.2%v/v)。干预前后采集了血液和粪便样本。通过 16S rRNA 基因测序分析肠道微生物群。连续 4 周每天饮用无酒精或酒精啤酒不会增加体重和体脂肪量,也不会显著改变血清心血管代谢生物标志物。无酒精和酒精啤酒增加了肠道微生物群的多样性,这与健康结果呈正相关,并倾向于增加粪便碱性磷酸酶活性,这是肠道屏障功能的标志物。这些结果表明,啤酒对肠道微生物群调节的影响与酒精无关,可能是由啤酒多酚介导的。
