地中海食
The concept of a Mediterranean diet was developed to reflect "food patterns typical of Crete, much of the rest of Greece, and Italy in the early 1960s". Although it was first publicized in 1975 by the American biologist Ancel Keys and chemist Margaret Keys (a husband and wife team), the Mediterranean diet failed to gain widespread recognition until the 1990s. Objective data showing that the Mediterranean diet is healthy originated from results of epidemiological studies in Naples and Madrid, confirmed later by the Seven Countries Study first published in 1970, and a book-length report in 1980.
