The Claim

Phenol-rich extra virgin olive oil acutely modulates gene expression related to oxidative stress and inflammation in healthy adults, but the clinical relevance of these changes for long-term cardiovascular disease prevention remains unproven.

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

How it works
1 study reviewed
In plain English

Consuming phenol-rich extra virgin olive oil changes the activity of genes involved in oxidative stress and inflammation in healthy adults within a short time, but it is not known whether these changes affect the risk of developing cardiovascular disease over the long term.

See the scientific wording

Phenol-rich extra virgin olive oil acutely modulates gene expression related to oxidative stress and inflammation in healthy adults, but the clinical relevance of these changes for long-term cardiovascular disease prevention remains unproven.

Why this might work

When phenol-rich olive oil is consumed, hydroxytyrosol enters the bloodstream and turns on specific genes that make proteins to neutralize harmful molecules produced during metabolism. These proteins break down damaging compounds, which lowers the level of oxidized fats in the blood.

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

    This study found that eating a special kind of olive oil high in antioxidants quickly changes how your body’s genes work to fight damage and inflammation. But it doesn’t prove yet that this actually lowers your risk of heart disease over many years.
