The Claim

In elderly individuals with a prior myocardial infarction, consumption of high-phenolic extra virgin olive oil for 26 weeks does not significantly alter plasma malondialdehyde levels, lecithin-cholesterol acyltransferase activity, or fasting plasma (poly)phenol concentrations, despite a significant increase in FRAP and PON-1 activity.

In plain English

In older adults who previously had a heart attack, drinking high-phenolic extra virgin olive oil for 26 weeks does not change plasma malondialdehyde levels, lecithin-cholesterol acyltransferase activity, or fasting polyphenol concentrations, but it does increase FRAP and PON-1 activity.

See the scientific wording

In elderly individuals with a prior myocardial infarction, consumption of high-phenolic extra virgin olive oil for 26 weeks does not significantly alter plasma malondialdehyde (MDA) levels, lecithin-cholesterol acyltransferase (LCAT) activity, or fasting plasma (poly)phenol concentrations, despite a significant increase in FRAP and PON-1 activity.

Why this might work

Special olive oil compounds enter the bloodstream and turn on a cellular switch that boosts the production of natural antioxidant tools. These tools make the blood better at neutralizing harmful molecules and protect an enzyme that cleans up damaged fats, but they do not reduce the amount of damaged fats in the blood or increase the levels of olive oil compounds that can be measured in the blood.

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

    Older people who had heart attacks and drank special olive oil for 6 months saw some of their body’s antioxidant defenses get stronger, but other signs of damage didn’t change—so the oil helps in some ways, but not all.
