The Claim

A single 25-gram dose of phenol-rich extra virgin olive oil reduces oxidized LDL and malondialdehyde levels within two hours in healthy adults, indicating acute suppression of lipid peroxidation that contributes to reduced atherosclerotic risk by limiting oxidative damage to arterial walls.

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 25 grams of phenol-rich extra virgin olive oil lowers levels of oxidized LDL and malondialdehyde in healthy adults within two hours, which reflects a reduction in lipid peroxidation and a decrease in oxidative damage to arterial walls.

See the scientific wording

A single 25-gram dose of phenol-rich extra virgin olive oil significantly reduces oxidized LDL and malondialdehyde levels within two hours in healthy adults, indicating an acute suppression of lipid peroxidation, which may contribute to reduced atherosclerotic risk by limiting oxidative damage to arterial walls.

Why this might work

After consuming phenol-rich olive oil, hydroxytyrosol enters the bloodstream and turns on genes that make more antioxidant enzymes. These enzymes clean up harmful molecules that damage fats in the blood, which stops the fats from becoming oxidized and forming dangerous compounds that harm arteries.

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

    Eating 25 grams of high-phenol olive oil in one meal quickly lowered harmful fat damage markers in the blood within two hours, which means it may help protect arteries from damage that leads to heart disease.
