How it works

The compounds in high-phenol olive oil turn on genes that make protective enzymes in the blood. These enzymes remove damaging molecules that interfere with fat processing. With less damage, the body clears fat from the blood faster after eating.

Most probable mechanism

In Simple Terms

After consuming olive oil rich in hydroxytyrosol, the compound enters the bloodstream and turns on genes that make more antioxidant enzymes. These enzymes clean up harmful molecules that damage fats, allowing the body to break down and remove fat from the blood faster after a meal.

Causal chain
1

Hydroxytyrosol and its derivatives are absorbed from the gastrointestinal tract and enter systemic circulation.

Supported by evidence
which leads to
2

Hydroxytyrosol activates transcription factors that bind to antioxidant response elements in DNA.

Verified by multiple studies
which leads to
3

Activated transcription factors increase the production of catalase and superoxide dismutase 1.

Verified by multiple studies
which leads to
4

Elevated catalase and superoxide dismutase 1 reduce reactive oxygen species and prevent oxidation of lipids.

Verified by multiple studies
which leads to
5

Reduced lipid oxidation improves the efficiency of triglyceride metabolism and clearance from the bloodstream.

Drinking 25 mL of high-phenolic extra virgin olive oil daily delivers 8 mg of tyrosol and hydroxytyrosol, more than the 5 mg/day recommended for antioxidant benefits, but blood levels of these compounds do not increase after fasting.
