Traditional diets shape unique gut microbes of Indian tribes, necessitating biobanking
Research on eight Indian tribal populations reveals that their traditional diets foster unique gut microbiomes, distinct from industrialised populations. The study, published in Gut Microbes, highlights the need for biobanking to preserve this microbial diversity and develop region-specific probiotic therapies. Trans-Himalayan tribes, with high dairy consumption, showed a more diverse microbiome, including a distinct strain of Bifidobacterium adolescentis, linked to improved gut health. The findings underscore India's unique microbial landscape and the potential impact of globalisation on these indigenous microbiomes.
Key Points
- Indian tribal populations possess unique gut microbiomes shaped by their traditional diets.
- These microbiomes differ significantly from those in industrialised settings.
- Biobanking of indigenous microbiomes is crucial before urbanisation erodes this diversity.
- High dairy consumption in trans-Himalayan tribes is linked to specific beneficial bacterial strains like Bifidobacterium adolescentis.
- The study advocates for region-specific probiotic interventions tailored to Indian communities.
