Traditional wisdom claims that moderate beer consumption may be beneficial for initiation of breastfeeding and enhancement of breastfeeding success. Here we review the question whether or not there is any scientific basis for this popular belief. There are clear indications that beer can stimulate prolactin secretion which may enhance lactogenesis both in non-lactating humans and in experimental animals. The component in beer responsible for the effect on prolactin secretion is not the alcohol content but apparently a polysaccharide from barley, which explains that the effect on prolactin can also be induced by non-alcoholic beer. No systematic studies are available to evaluate the clinical effects of beer on induction of lactogenesis, and short term studies have shown a reduced breast milk intake by infants after moderate alcohol consumption of their mothers. It is conceivable that relaxing effects of both alcohol and components of hop might also have beneficial effects on lactogenesis is some women, but there is no hard evidence for causal effects. It appears prudent not to generally advocate the regular use of alcoholic drinks during lactation but to rather refer mothers to non-alcoholic beer, even though no adverse effects of an occasional alcoholic drink during lactation have been documented.
传统观点认为，适度饮用啤酒可能有助于启动母乳喂养并提高母乳喂养的成功率。在此，我们审视这一普遍观念是否有任何科学依据。有明确迹象表明，啤酒能刺激催乳素分泌，这可能在非哺乳期人类和实验动物中增强泌乳作用。啤酒中对催乳素分泌起作用的成分并非酒精含量，而是显然来自大麦的一种多糖，这就解释了无醇啤酒也能诱导对催乳素的作用。目前尚无系统研究来评估啤酒对泌乳诱导的临床效果，短期研究表明，母亲适度饮酒后，婴儿的母乳摄入量会减少。可以想象，酒精和啤酒花成分的放松作用可能对一些女性的泌乳也有有益影响，但尚无确凿证据证明存在因果关系。似乎谨慎的做法是，一般不提倡在哺乳期常规饮用酒精饮料，而应推荐母亲饮用无醇啤酒，尽管尚无文献记载哺乳期偶尔饮用酒精饮料会产生不良影响。
