BACKGROUND<\/strong>
\nA carbon footprint is the sum of greenhouse gas emissions (GHGEs) associated with food production, processing, transporting, and retailing.<\/p>\n

OBJECTIVE<\/strong>
\nWe examined the relation between the energy and nutrient content of foods and associated GHGEs as expressed as g CO2 equivalents.<\/p>\n

DESIGN<\/strong>
\nGHGE values, which were calculated and provided by a French supermarket chain, were merged with the Composition Nutritionnelle des Aliments (French food-composition table) nutrient-composition data for 483 foods and beverages from the French Agency for Food, Environmental and Occupational Health and Safety. Foods were aggregated into 34 food categories and 5 major food groups as follows: meat and meat products, milk and dairy products, frozen and processed fruit and vegetables, grains, and sweets. Energy density was expressed as kcal\/100 g. Nutrient density was determined by using 2 alternative nutrient-density scores, each based on the sum of the percentage of daily values for 6 or 15 nutrients, respectively. The energy and nutrient densities of foods were linked to log-transformed GHGE values expressed per 100 g or 100 kcal.<\/p>\n

RESULTS<\/strong>
\nGrains and sweets had lowest GHGEs (per 100 g and 100 kcal) but had high energy density and a low nutrient content. The more-nutrient-dense animal products, including meat and dairy, had higher GHGE values per 100 g but much lower values per 100 kcal. In general, a higher nutrient density of foods was associated with higher GHGEs per 100 kcal, although the slopes of fitted lines varied for meat and dairy compared with fats and sweets.<\/p>\n

CONCLUSIONS<\/strong>
\nConsiderations of the environmental impact of foods need to be linked to concerns about nutrient density and health. The point at which the higher carbon footprint of some nutrient-dense foods is offset by their higher nutritional value is a priority area for additional research.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-29697","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"From the Center for Public Health
