Greece was well-known for its traditional Mediterranean diet in the 1960s. Both cohorts in Greece were characterized by their very high intake of olive oil. Crete was known for its apparent longevity. The Cretan cohort was joined to the HALE project.
The cohort of Crete was made up by men resident of rural villages located inland from the northern coast, east of the capital of Heraklion where the habitual diet was very high in olive oil.
The cohort of Corfu was made up by men resident of seven rural villages located in the northern part of the island, among the highest olive oil consuming regions worldwide.
