Does Olive Oil actually make a difference, or is it overhyped?

Olive oil is one of the most extensively studied single foods in longevity research, both through its central role in Mediterranean-diet trials and in large cohort studies of the oil itself. Weighing the data: Olive Oil looks well-supported and consequential — the evidence is rated strong (88/100) and its estimated impact on longevity is also rated highly (80/100), making it one of the more solidly-backed choices on Vitaebase.
