This randomized controlled trial evaluated the impact of long-term consumption of extra-virgin olive oil (EVOO) on plasma total antioxidant capacity (TEAC) in 34 older adults at high cardiovascular risk. Results indicated that post-myocardial infarction participants experienced a significant increase in TEAC of +402 μM, and those with high Mediterranean diet adherence showed an increase of +274 μM, suggesting that dietary context influences antioxidant responses.
Key findings
- Post-MI participants showed a TEAC increase of +402 μM compared to healthy controls.
- Participants with high Mediterranean diet adherence had a TEAC increase of +274 μM.
- No significant TEAC differences were observed between HP-EVOO and refined olive oil groups.
Why it matters
Understanding how dietary patterns, such as adherence to the Mediterranean diet, influence antioxidant responses can help clinicians tailor dietary recommendations for older adults, particularly those at high cardiovascular risk.
