The Claim

Among older adults with metabolic syndrome, higher consumption of common olive oil is associated with lower gut microbiota alpha diversity, as indicated by significant negative trends across the Chao1, Simpson, Shannon, and Inverse Simpson indices.

In plain English

In older adults with metabolic syndrome, eating more regular olive oil is linked to having a smaller variety of gut bacteria. This pattern is seen when measuring gut bacteria in four different ways.

See the scientific wording

Higher consumption of common olive oil is associated with lower gut microbiota diversity (alpha diversity) in older adults with metabolic syndrome, with significant negative trends across all four diversity indices (Chao1, Simpson, Shannon, and Inverse Simpson).

Why this might work

Eating regular olive oil brings more fat into your gut. Your body releases extra bile to digest the fat. The extra bile kills many kinds of bacteria, so only a few types survive. This lowers the variety of bacteria in your gut.

What the research says

1 study
  1. Study: Total and different types of olive oil consumption, gut microbiota, and cognitive function changes in older adults

    Eating more common olive oil is linked to having fewer types of gut bacteria, and this study found that connection in older adults with metabolic syndrome.
