Existe-t-il un modèle alimentaire optimal ?

Adequate nutrients intake is important for the maintenance of health and the prevention of chronic diseases. The deal is to design a food intake pattern that is healthy while maintaining the intake of local and culture specific foods. Food models meeting these requirements are useful in the development of practical and achievable dietary guidelines. Taking into account the results of many observational and interventional studies, the Mediterranean diet and the Nordic diet are close to an optimal diet, in southern and septentrional occidental countries respectively. Other models such as paleolithic, vegeterian or vegan diets may be also healthy, however they are less realistic and more stringent for occidental populations.
