The Claim

Consuming 25 mL per day of high-phenolic extra virgin olive oil (containing 123.1 mg/kg tyrosol and 233.6 mg/kg hydroxytyrosol) for 26 weeks significantly increases serum ferric reducing antioxidant power (FRAP) by 67.7 μM Fe²⁺ and paraoxonase-1 (PON-1) activity by 3.68 U/mL in elderly individuals (mean age 74) with a prior myocardial infarction, compared to baseline.

In plain English

In elderly individuals with a prior heart attack, daily consumption of 25 mL of high-phenolic extra virgin olive oil for 26 weeks increases serum antioxidant capacity by 67.7 μM Fe²⁺ and paraoxonase-1 activity by 3.68 U/mL compared to baseline levels.

See the scientific wording

Consuming 25 mL per day of high-phenolic extra virgin olive oil (containing 123.1 mg/kg tyrosol and 233.6 mg/kg hydroxytyrosol) for 26 weeks significantly increases serum ferric reducing antioxidant power (FRAP) by 67.7 μM Fe²⁺ and paraoxonase-1 (PON-1) activity by 3.68 U/mL in elderly individuals (mean age 74) with a prior myocardial infarction, compared to baseline, suggesting enhanced antioxidant capacity in this high-risk population.

Why this might work

Special compounds in olive oil enter the bloodstream and turn on a cellular switch that makes more antioxidant proteins. These proteins neutralize harmful molecules in the blood and protect an enzyme that prevents fat damage in cholesterol particles, leading to stronger overall antioxidant defense.

  1. Study: High-Tyrosol/Hydroxytyrosol Extra Virgin Olive Oil Enhances Antioxidant Activity in Elderly Post-Myocardial Infarction Patients

    This study found that elderly people who had a heart attack and drank a specific kind of high-phenol olive oil every day for six months showed better antioxidant markers in their blood, meaning their bodies got better at fighting harmful molecules. This matches exactly what the claim says.
