The is widely recognised as one of the healthiest and most sustainable eating patterns in the world. Rooted in the olive-growing regions of the Mediterranean basin, it is more than a dietary model – it is a cultural heritage shaped by centuries of tradition, with olive oil at its heart.
Although its origins are ancient, the Mediterranean diet began gaining international scientific recognition in the 1960s, thanks to the pioneering work of Professor and the landmark Seven Countries Study. This momentum grew through the collaborative efforts of leading institutions such as the , the and . Their work led to the creation of the now-iconic Traditional Healthy Mediterranean Diet Pyramid, first presented in the early 1990s, and supported by scientific publications that reshaped global nutrition thinking.
Since then, decades of research have confirmed the Mediterranean diet’s ability to reduce cardiovascular risk, improve cognitive function, combat cellular ageing, and even help prevent certain types of cancer. Its emphasis on plant-based foods, seasonal produce, moderate consumption, and above all, extra virgin olive oil, make it a model for both human and planetary health. In recognition of its cultural value, the Mediterranean diet was inscribed by UNESCO in 2013 as an Intangible Cultural Heritage of Humanity.

In this section of the IOC’s website, you can listen to theof the experts’ thoughts on the challenges and opportunities of the Mediterranean diet. These videos highlight the ongoing contributions of researchers who have shaped global awareness of the Mediterranean diet and continue to advance its role in nutrition science, cultural preservation and sustainable development.
