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.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
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).
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 studyEating 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.
