A new study published in Cell Host & Microbe has compared the development of the microbiota in breast-fed and formula-fed infants. In the trial, 210 infants were randomly assigned to be breast-fed or to receive one of four formulas containing varying supplements, such as bifidobacteria or galacto-oligosaccharides, during the first year of life. The researchers found similar faecal bacterial communities between breast-fed and formula-fed infants, but differences across time points. There were large differences in metabolite profiles between breast-fed and formula-fed infants. In addition, it was demonstrated that bacterial circadian rhythmicity develops early, is affected by diet and increases with age.

发表在《细胞宿主与微生物》上的一项新研究比较了母乳喂养和配方奶喂养婴儿的微生物群发育。在试验中，210 名婴儿在出生后的第一年被随机分配接受母乳喂养或接受含有不同补充剂（例如双歧杆菌或低聚半乳糖）的四种配方奶粉中的一种。研究人员发现母乳喂养和配方奶喂养的婴儿之间的粪便细菌群落相似，但不同时间点之间存在差异。母乳喂养和配方奶喂养的婴儿之间的代谢特征存在很大差异。此外，研究表明，细菌的昼夜节律发展较早，受饮食影响，并随着年龄的增长而增加。
