The Claim

Higher consumption of virgin olive oil is associated with greater diversity of gut microbiota, as indicated by higher Chao1 and Inverse Simpson indices, in older adults with metabolic syndrome, suggesting a potential prebiotic effect of polyphenol-rich virgin olive oil on gut microbial richness.

In plain English

Older adults with metabolic syndrome who eat more virgin olive oil tend to have a wider variety of helpful bacteria in their gut, and the polyphenols in the oil may act as food for these bacteria.

See the scientific wording

Higher consumption of virgin olive oil is associated with greater diversity of gut microbiota, as indicated by higher Chao1 and Inverse Simpson indices, in older adults with metabolic syndrome. This suggests a potential prebiotic effect of polyphenol-rich virgin olive oil on gut microbial richness.

Why this might work

When people eat virgin olive oil, special plant chemicals from the oil go into the gut. These chemicals feed the good bacteria and stop the bad ones, so more different kinds of bacteria can grow. This makes the gut a healthier place with a wider variety of microbes.
