The researchers in this Australian study interviewed 102 people of Mediterranean origin about their diet and also observed their food preparation techniques. The researchers grouped the diets into Western, Eastern, North African and Adriatic groups and detailed the components of the diets. They also cross-checked their findings with a number of diet books from different countries.
What I found particularly interesting was a reference to earlier literature referencing a wide variation in individual components of the diet between countries. For example there was four fold difference in fruit consumption between the highest and lowest consuming groups as well as a four-fold difference in vegetable consumption. The authors also reference differences in life expectancy between the countries.
The results of the present study are summarised in Tables 1 and 2 which identify both the frequency of consumption of the diet as well as the components of the diet. The components of the diet detailed here range from Melokhia and Okra through to Focaccia and preserved Walnut. The researchers identified similar diets in neighbouring countries and increasing differences with geographical separation.
This is a detailed study looking at differences in the Mediterranean diet across the Mediterranean region. There is also a reference to the literature for further reading.
