Ancel Keys and his Italian colleague Flaminio Fidanza and their colleagues at the Seven Countries Study were central to the modern recognition, definition, and promotion of the eating pattern they found in Italy and Greece in the 1950s and ’60s, now popularly called “The Mediterranean Diet”.
Ancel Keys was the first researcher who associated the traditional Mediterranean diet with a low risk of CHD. However, “the” Mediterranean diet does not exist. The Mediterranean Sea borders 18 countries that differ markedly in geography, economic status, health, lifestyle, and diet.
Scores on the Mediterranean diet
Mediterranean Adequacy Index (MAI). An index score based on typical Mediterranean foods: bread, cereals, legumes, potatoes, vegetables, fruit, fish, olive oil, and wine and non-typical Mediterranean foods: milk, cheese, eggs, meat, hard fats and sweet products.
Mediterranean Diet score (MDS). A score indicating compliance to the Mediterranean diet. A high intake of Mediterranean foods: cereals, legumes, fruit, vegetables, fish, Mon-unsaturated fatty acids to Saturated fatty acids (M/S) ratio, and wine were scored positive (1) and a high intake of the non-Mediterranean foods: dairy and meat negative (0). The score ranged from 0 to 9 and the higher the score the better the compliance to a traditional Mediterranean diet.
