最新研究发现,啤酒有益于男性肠道菌群健康

2022-06-20 生物世界 生物世界

结果表明,啤酒对肠道菌群调节的影响与酒精本身无关,可能由啤酒中富含的多酚类物质介导。

众所周知,喝酒有害健康,许多研究表明,酒精是一种致癌物,喝酒与包括癌症在内的一系列伤害和疾病有关。但生活中williamhill asia 也经常听到一种说法:小酌怡情,适度饮酒有益健康。

近日,美国化学会(ACS)旗下期刊 Journal of Agricultural and Food Chemistry 上发表了一篇题为:Impact of Beer and Nonalcoholic Beer Consumption on the Gut Microbiota: A Randomized, Double-Blind, Controlled Trial 的研究论文。

这是一项随机、双盲对照实验,以探究啤酒无酒精啤酒肠道菌群的影响,实验结果显示,连续4周每天饮用330ml 含酒精啤酒或无酒精啤酒,都会增使得肠道菌群多样性更高,粪便碱性磷酸酶水平更高,这表明肠道健康有所改善。

该研究招募了22名健康男性,随机平均分配到两组,在为期4周的研究期间,分别每天饮用330mL的酒精啤酒,或正常啤酒(5.2%酒精度)。

在开始研究前和研究结束后,分别收集他们的血液和粪便样本。通过16S rRNA 测序分析他们的肠道菌群。

实验结果显示,连续4周,每天饮用无酒精啤酒或含酒精啤酒,不会增加体重和体脂,也不会显著改变血清心脏代谢生物标志物。

此外,该研究表明,无酒精啤酒和含酒精啤酒都增加了肠道菌群的多样性,这与积极的健康结果相关,还增加了参与者粪便碱性磷酸酶活性,这是肠道屏障功能的标志。这些结果表明,啤酒对肠道菌群调节的影响与酒精本身无关,可能由啤酒中富含的多酚类物质介导。

然而,2018年8月,国际顶尖医学期刊《柳叶刀》发表了一项对全球195个国家和地区的酒精使用负担的大型研究,该研究指出酒精是全球15至49岁男性和女性患病和早逝的主要风险因素,全球近十分之一人口的死亡是饮酒所致。该研究得出的结论是:对健康危害最小的饮酒量就是完全不饮酒

2021年7月,《柳叶刀·肿瘤学》发表了世界卫生组织国际癌症研究机署(IARC)领导的一项大型研究研。该研究指出,2020年有超过74万人因喝酒导致癌症,即使是少量饮酒也会明显增加癌症发病率。

这两项大规模研究都指出,即使适度饮酒,也有害健康

该论文的作者也赞同这一观点,他们指出,最安全的饮酒量是不饮酒,因此,无酒精啤酒可能是一个更健康的选择。
