Environmental and nutritional analysis of the EAT-Lancet diet at the individual level: insights from the NutriNet-Santé study

The EAT-Lancet Commission has recently proposed a “universal” healthy reference diet. However, no study specifically investigated its possible environmental benefits at the individual level based on observed data. Our objective was therefore to characterize pressures and impacts related of adherence diet among French adults. Dietary data from 264-item FFQ in 29,210 NutriNet-Santé participants (75% women, mean age = 53.5y (SD 14.0)), were used estimate (i) through index (ELD-I), (ii) food production-related using 3 indicators (greenhouse gas emissions, cumulative energy demand land occupation) (iii) overall impact validated aggregated partial score (pReCiPe). For clarity purpose, results are presented by quintile (Q) ELD-I. High ELD-I (Q5), compared low (Q1), associated with lower greenhouse emissions (−56%), (−31%) occupation, (−54%). pRECIPE 62% high than but range pReCiPe Q1 large. In this large scale-study adults, recommendations led impacts. Nonetheless, some low-EAT diets (reflecting unhealthy diets), may exhibit
