ABSTRACT
BACKGROUND:
The diet proposed by the EAT-Lancet Commission, which supports both health and environmental sustainability, provides an opportunity to assess the sustainability of food-based dietary guidelines.OBJECTIVES:
The primary objective was to assess the alignment of the 2019 Canada's Food Guide (CFG) with the EAT-Lancet diet. To do so, an index assessing adherence to the EAT-Lancet diet was developed and evaluated.METHODS:
Data from 1147 adults were used from the cross-sectional PRÉDicteurs Individuals, Sociaux et Environnementaux (PREDISE) study conducted between 2015 and 2017 in the province of Québec. The EAT-Lancet Dietary Index (EAT-I) was developed to evaluate adherence to the EAT-Lancet diet. Adherence to the 2019 CFG was assessed using the Healthy Eating Food Index (HEFI)-2019. Associations between the HEFI-2019 score and component scores and the EAT-I score were examined using linear regression models.RESULTS:
The mean EAT-I score (/80) in this population was 33.4 points [95% confidence interval (CI) 32.2, 34.6]. EAT-I scores were consistent with expected differences in diet quality between females and males (+6.9 points, 95% CI 4.8, 9.0) and between adults aged 50-65 y and 18-34 y (+4.3 points, 95% CI 1.6, 7.0). The mean HEFI-2019 (/80) score was 44.9 points (95% CI 44.1, 45.7). The HEFI-2019 was strongly associated with the EAT-I (ß = 0.76, 95% CI 0.72, 0.80). Among the 10 components of the HEFI-2019, components such as the whole-grain foods (ß =4.01, 95% CI 3.49, 4.52), grain foods ratio (ß =3.65, 95% CI 3.24, 4.07), plant-based protein foods (ß =2.41, 95% CI 2.03, 2.78), and fatty acids ratio (ß =3.12, 95% CI 2.72, 3.51) showed the strongest associations with the EAT-I.CONCLUSIONS:
These results suggest that recommendations in the 2019 CFG are largely coherent with the EAT-Lancet diet underscoring the complementarity and compatibility of the 2019 CFG for sustainability and health promotion purposes.Palavras-chave
