The Claim

A single 25-gram dose of phenol-rich extra virgin olive oil upregulates gene expression of catalase, superoxide dismutase 1, and upstream transcription factor 1 within two hours in healthy adults.

Source: Effects of postprandial hydroxytyrosol and derivates on oxidation of LDL, cardiometabolic state and gene expression: a nutrigenomic approach for cardiovascular prevention.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

How it works
1 study reviewed
In plain English

Consuming 25 grams of phenol-rich extra virgin olive oil increases the activity of genes involved in antioxidant defense in healthy adults within two hours.

See the scientific wording

A single 25-gram dose of phenol-rich extra virgin olive oil upregulates gene expression of catalase, superoxide dismutase 1, and upstream transcription factor 1 within two hours in healthy adults, suggesting an acute activation of endogenous antioxidant defense pathways.

Why this might work

After consuming phenol-rich olive oil, hydroxytyrosol enters the bloodstream and turns on a specific gene regulator that switches on the production of three key proteins that destroy harmful molecules in cells.
