This article conflates diversity with gut health. It has not been proven that more diversity is necessarily better[1]. In fact, in infants a less diverse b. infantis dominant environment is probably advantageous[2]. If you're having a baby, the best thing you can do is to supplement b. infantis, especially the robust strain from Evolve Biosystems[3]. The Hadza have more b. infantis[4] which kicks off a set of immune host interactions that have positive effects on inflammation during the critical period after birth[5]. "After around 3 years, the gut microbiota stabilises retaining relative proportions of taxa with adaptations to composition harder to impose,"[6] so I doubt it's diet as much as it is vertical transmission of the right kinds of bacteria that set the infants up for a lifetime of healthy immune response. 1. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5103657/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5103657/ 2. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6177445/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6177445/ 3. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7352178/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7352178/ 4. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9894631/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9894631/ 5. https://www.sciencedirect.com/science/article/pii/S0092867421006607 https://www.sciencedirect.com/science/article/pii/S009286742... 6. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6950569/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6950569/
