Greater gut bacteria diversity linked to lower frailty in older women
A study linked greater gut bacteria diversity with lower frailty in older women.
It included 2,081 women aged 75 to 80, who had health assessments and stool tests.
Frailty can involve weight and muscle loss, reduced strength and physical decline, raising the risk of falls, fractures, hospital stays and death.
The study was observational, so it cannot show that gut bacteria cause or prevent frailty.
The findings add to interest in how the gut may relate to healthy ageing, including through inflammation and muscle function.
A varied diet with fruit, vegetables, whole grains and beans can provide fibre that supports gut microbes, while activity, sleep and stress also affect gut health.
Researchers say more studies are needed to clarify the relationship.
Older women with greater diversity in their gut bacteria tended to have lower levels of frailty, according to a study published in Nature Communications.
The observational study included 2,081 women aged 75 to 80.
Researchers assessed participants’ health and physical function and analyzed genetic material from microbes in stool samples.
The study cannot show that gut bacteria diversity causes or prevents frailty, and the researchers said more research is needed.
Nutrition experts cited in the article said diet and other lifestyle factors can affect gut microbiota.
- Who
- 2,081 women aged 75 to 80 took part in the study.
- What
- The study found that greater gut bacteria diversity was linked to lower frailty.
- When
- The study was published in July. The article was published on October 13, 2026.
- Where
- Not stated
- Why
- The study examined the relationship between gut microbiota and frailty. It does not establish that one causes or prevents the other.
This story does not have two clearly opposing sides.
The study was published in Nature Communications.
Folha published an article about the study.

What people are saying
The microbiota is increasingly recognized for keeping the body's functions in balance, participating in the regulation of metabolism, the immune system, inflammation, and processes related to muscle function and the neuroendocrine system.
The article mentions the role of bacteria, such as Faecalibacterium prausnitzii, in producing substances that regulate inflammation.
