The Barilla Center for Food and Nutrition (BCFN) has produced an updated version of the traditional Food Pyramid based on the Mediterranean Diet in order to assess the simultaneous impact that food has on human health and the environment. The Double Pyramid model demonstrates how the foods recommended to be consumed most frequently are also those exerting less environmental impact, whereas the foods that should be consumed more periodically are those characterized by a higher environmental impact. The environmental impacts resulting from two different menus were compared. All menus were equally balanced and comparable in terms of nutrition, but they differed in relation to the presence of absence of animal flesh and animal products.. The results obtained suggest that a diet based on the principles of the Mediterranean Diet, as suggested by the Double Pyramid, generates a lower environmental impact compared to diets that are heavily based on daily meat consumption.

Introduction. The nutritional value of the Mediterranean diet has been widely recognized. At the same time, the Mediterranean Diet has been taken by FAO as an example of Sustainable Diet, for its features of healthiness, affordability and low environmental impact. As more and more studies document the interrelation between food choices, nutritional adequacy and environmental impact, the Barilla Center for Food & Nutrition (BCFN) decided to develop a graphic model to help people achieving a healthy and sustainable diet. Starting from the Mediterranean Diet, in 2010 BCFN published the first edition of the Double Food and Environmental Pyramid, a graphic tool that reproposes the traditional food pyramid model, combining it with the environmental impacts of food. Investigative Method. The Double Pyramid is a graphic tool consisting in two frameworks. The Food Pyramid on the left is based on the Mediterranean Diet pattern, and it classifies the food depending on the frequency on which they should be consumed. It suggests that a balanced diet should be based mainly on food of plant origin, while the consumption of food with increasing energy density, like red meat or sweets, should be moderated or limited. In the Environmental Pyramid, placed upside-down next to the first one, the same foods are classified depending on their impact on the environment. The environmental impacts of foods were calculated through the LCA methodology, using data for impact per kilo of product. The indicators chosen to express the impacts are Carbon, Water and Ecological Footprint. Data on the environmental impact were taken from scientific researches and available public data, and collected by BCFN into a database that up to now contains more than 1,180 data and 350 public sources. Results. Combining the two pyramids makes possible to show that two different, but equally important objectives overlap in the same dietary pattern: health and environmental protection. The Double Pyramid demonstrate that foods that should be consumed more frequently (fruit, vegetables, grains) are also those with lower environmental impact, whereas foods whose consumption should be moderate or limited are those with higher environmental impact. Indeed, our analysis shows that plant foods have an environmental impact that is sensibly lower than products of animal origin. For example, 1kg of bovine meat has a water footprint which is 61 times higher to the one associated to the same amount of vegetables ((18,870lt vs 310lt), and 11 times higher to pastas water footprint (1,770lt). Similarly the carbon footprint of fruit (475 gr CO2eq) and vegetables (820 gr CO2eq) are up to 55 times lower that the one of red meat (26,170 gr CO2eq). Starting from the second edition of the Double Pyramid, BCFN decided to identify the most efficient ways to spread the culture of sustainable diet. For this reason, it was created a tool that calculates both nutritional values and environmental impacts of dishes and foods commonly eaten. The calculation tool is not aimed at giving nutritional advices from a medical point of view, rather than raising peoples awareness on the environmental impacts of different food

choices. The database used for the calculation contains specific nutritional and environmental values of more than 220 ingredients. To estimate the extent to which the food choices of individuals affect the environment, two different daily menus were analyzed. Both were balanced from a nutritional point of view, but the first one relies mostly on proteins from plant origin (lacto-ovo-vegetarian menu), while the second is made from animal origin (meat menu). Results show that the Carbon Footprint of the meat menu is 2.6 times higher than the vegetarian one in terms of Carbon (6,497.1g Co2eq compared to 2,483.9g CO2eq), and nearly the same proportion exist between the Water Footprint of the two menus. Conclusion. Our analysis demonstrate that even little changes in the dietary pattern can result in significant changes in terms of environmental impact. For example, limiting the consumption of meat to just twice a week, it could be possible to save up to 2,868 grams of carbon dioxide and 2.021 liters of water per person per day. The results from this analysis can be useful to elaborate educational campaign aimed at modifying peoples eating habits. Indeed, we demonstrated that it is possible to adopt a healthy, sustainable diet without overturning culinary traditions and personal preferences.
