  27. 27. CommentAncel Keys’ original message was (esp. In the USA) lost in ”fat-is-bad mantra – although the message was in the ”Mediterranean diet” of Ancel Keys was unsaturated fats over saturated.Thus fats in esp. the USA were replaced with sugars, with obesity epidemic as result.Mediterranean diet is a balanced diet, with quality of fat plus fruits and vegetables as key – with proper amount of calories with regular physical activity.12/04/12 Pekka Puska, Director General
