(Russell Mclendon/ Science Alert) — The Mediterranean diet has become famous far beyond its namesake sea, as research increasingly supports its longstanding reputation for boosting health and longevity.

Studies have shown that people on the Mediterranean diet – which emphasizes plant-based foods and fish, and not so much red meat or dairy – tend to be healthier in multiple ways, with lower rates of heart disease, cancer, diabetes, dementia, and overall mortality.

But why? Despite strong evidence for health benefits, it remains unclear how exactly this mix of foods, at the cellular level, can lengthen lifespan.

That may be changing, though. A study led by researchers from Stanford University in the US has revealed cellular effects of the Mediterranean diet for the first time, based on how one of its healthy fats influenced lifespan in nematodes, also known as roundworms.

Finding this link is a big deal, the study’s authors say, offering new insights on the health effects of various fats and the role diet plays in longevity. (…)
