SUMMARY:

The various impacts caused by current food systems highlight the urgency of adopting healthier and more sustainable diets. The analysis of the environmental impacts of different populations’ diets helps to identify the necessary actions to achieve sustainability, considering all dimensions. This work aims to evaluate the environmental footprints of food (EFF) of people residing in the city of Natal/RN. Data from 411 people aged ≥20 years from the BRAZUCA Natal Study were used. Food consumption data were assessed using a 40-item Propensity Questionnaire. The environmental footprints of food (Water Footprint - WF, Carbon Footprint - CF, and Ecological Footprint - EF) were estimated considering food consumption data for each 1,000 kcal. The variables socioeconomic and demographic characteristics, Body Mass Index (BMI), food security, adherence scores to the Dietary Guidelines for the Brazilian population, and practices related to the purchase and consumption of food were also evaluated. The Mann-Whitney and Kruskal-Wallis tests were performed to verify the difference between EFF values of the same variable categories. Correspondence Analysis (CA) was performed to assess associations between EFF (divided into tertiles) and other variables. The estimated per capita value of CF, WF and EF of the diet was 1,709.78 gCO2eq/person/day/1,000 kcal, 1,901.81 L/person/day/1,000 kcal and 12.28 m2/person/day/1,000 kcal, respectively. Beef and chicken were the foods that most contributed to the value of all three footprints (52.7% for CF, 41.2% for WF, and 37.6% for EF). The highest EFF values were seen in males, with higher levels of education and family income, in food security, with a higher frequency of fast-food purchase, greater frequency of use food delivery services, and consumption 1 to 2 days/week in cafeterias. Considering the CA results, lower EFF, referring to the first tertile, was associated with social vulnerability variables (female gender, non-white race, lower family income strata, and food insecurity). The last tertile, referring to higher EFF, was associated with variables related to better living conditions (male gender, white race, higher strata of family income, and food security). The third tertile was also associated with a higher frequency of purchases in fast-food restaurants and cafeterias, a higher frequency of food delivery services use, and a lower frequency of food purchases at street markets. Regarding food consumption, the third tertile consumed more meats, fruits, vegetables, and dairy products than the first tertile. On the other hand, the first tertile showed higher consumption of bread and sugar. These results allow us to understand how individual characteristics influence access to food and EFF values. Recognizing these relationships is of great importance as it makes it possible to guide individual and public actions to promote healthier and more sustainable diets for all.
