Study finds South Asian guts need region-specific health advice
Scientists studied the tiny organisms living in the guts of people from India and Sri Lanka.
They found that different South Asian communities can have different gut microbiomes.
These differences may be linked to food, culture, geography and daily habits.
Moving toward city lifestyles was linked with changes in the gut’s microbial communities.
City-related habits can include eating more packaged foods, eating less fibre and sleeping irregularly.
This does not prove that cities directly cause unhealthy guts.
Experts suggest eating a variety of minimally processed foods and following nutritious traditional eating patterns.
Scientists need larger and longer studies before gut tests can routinely prescribe personal diets.
Researchers analysed stool samples and lifestyle, dietary and health data from 575 healthy adults across 10 communities in India and Sri Lanka.
The study found South Asian gut microbiomes differ from profiles reported in other parts of the world.
Diet, culture, geography, lifestyle and urbanisation were associated with differences in gut microbial communities.
Urbanisation-related changes included lower microbial diversity and higher levels of some disease-associated taxa.
Experts say diverse, minimally processed foods may help, but microbiome-based personalised diets are not yet ready for routine use.
- Who
- Researchers studied 575 healthy adults from 10 South Asian communities, with comments from Dr Nishant Kurian of PSRI Hospital.
- What
- The study examined how South Asian gut microbiomes differ and how diet, lifestyle and urbanisation may shape them.
- Where
- The communities were located in India and Sri Lanka.
- When
- The research is described as a recent study; no specific date is provided.
- Why
- The research may help determine whether gut-health and nutrition advice developed from Western populations applies equally to South Asians.

“Truly personalised nutrition is still developing. Initial studies are promising, but larger, longer-term studies are needed before microbiome testing can be used routinely to guide individual treatment.”

“The point is there may not be one formula for a ‘healthy gut’ that fits all. Our regional diets, culture and environment influence Indian gut microbiomes.”
