[Shapes or icons from the dietary guidelines. A reality going beyond healthy food].

BACKGROUND
icons or shapes represent the development and approval of dietary guidelines including recommendations of food consumption and nutrient intakes according to the behavioral models of countries worldwide. The Food and Agriculture Organization (FAO) collected and recognized them.


METHODS
websites of food-based dietary guidelines of the FAO. Websites of the different Spanish scientific societies that have elaborated and developed them, including the Mediterranean Diet Foundation.


RESULTS
in all, 94 countries are collected in the FAO food guidelines website, with predominant models of 33 diet plates and 51 food pyramids, emerging 11 as new graphics systems, that reflect, in addition to food: 52, physical activity; 63, water or hydration; 20, social and emotional values; and 13, reduction or elimination of alcoholic beverages.


CONCLUSIONS
the models with icons or shapes so far are consistent with the modes of distribution of food at meals and adapting to new criteria that include behavioral guidelines. New designs are incorporated that include food safety guidelines in generic graphic structures that do not represent any of the classic models: food plates or food pyramids.
