Regular consumption of extra virgin olive oil is associated with better cardiovascular health and improved liver health due to the presence of polyphenols.
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.
In elderly people, high-phenolic extra virgin olive oil increases FRAP and PON-1 antioxidant activity only in those who have had a heart attack, not in those who have not, when both groups consume the same amount and have similar baseline health.
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.
Elderly people who have had a heart attack have lower levels of a specific antioxidant enzyme in their blood compared to healthy elderly people, and consuming high-phenolic extra virgin olive oil for 26 weeks increases this enzyme level partially.
