In a
previous study of 24 healthy women, vaginal microbiome
composition became less diverse between the second and third trimesters of pregnancy and just before delivery was enriched with Lactobacillus species, likely contributing to vertical transmission of these bacteria during vaginal birth.21 In a
study of 10 newborns in Venezuela, within hours of delivery, the intestinal tracts of infants born vaginally were colonized by Lactobacillus and Prevotella, whereas infants delivered operatively acquired bacteria present on the mother's skin and the hospital environment, such as Staphylococcus, Proprionibacterium, and Corynebacterium.15 Quiz Ref ID Our findings, based on a large group of 6 - week - old infants, indicated that Lactobacillus also contributes to the microbial environment of the gut but to a lesser extent
than Bifidobacteria, Bacteroides, and Streptococcus.
Thanks to a
previous study, the scientists already knew that replacing the traditional three big meals per day with 6 smaller meals worked better for shedding fat and building muscle, so now they wanted to find out whether 6 solid meals per day provided better results in terms of body
composition and physical performance
than 3 solid meals and 3 protein shakes per day.
