However, current instruments measuring adherence to the EAT-Lancet planetary health diet are unsuitable for large-scale surveys. Simplified tools assessing consumption frequency can improve response rates, lower costs, and facilitate administration. OBJECTIVES: This study aimed to develop a practical and concise index for evaluating relative adherence to the EAT-Lancet diet across large-scale multicountry surveys. METHODS: First, the EAT-Lancet Consumption Frequency Index (ELFI) was developed using a brief food propensity questionnaire of 14 food groups representing the planetary health diet from the Food systems that support transitions to hEalthy And Sustainable dieTs survey, which encompassed 27 European countries (n = 27,417). Subsequently, ELFI was further validated using 24-h dietary recalls from the Third French Individual and National Food Consumption Survey (n = 1645), correlating it with the valid EAT-Lancet Index (ELI), which evaluates absolute adherence, as well as with food group consumption, measures of nutritional health (nutrient adequacy and diet quality), and environmental impact. Analyses included assessment of reliability, structural validity, concurrent validity, and nomological validity. RESULTS: ELFI showed strong reliability (α > 0.80) and factor analysis revealed a 2-factor solution: \"foods to encourage\" and \"foods to balance and to limit.\" Confirmatory factor analysis demonstrated that ELFI is structurally valid. Concurrent validity was confirmed as it was associated with sex, age, education, income, household size, physical activity, and smoking habit (P < 0.05). ELFI correlated with ELI (0.44, P < 0.0001) and food group consumptions. Regarding nomological validity, the ELFI subscores for \"foods to encourage\" and \"foods to balance and to limit\" were associated with better nutritional health (β = 0.62 and 0.23, respectively; P < 0.0001) and a lower environmental impact (β = -0.16 and -0.36, respectively; P < 0.0001). CONCLUSIONS: ELFI approach represents a valuable and easy-to-implement index for evaluating relative adherence to sustainable and healthy diets in large-scale multicountry studies.","is_dataset_classified":null,"base_score":1.0986122886681096,"endowment":1.0986122886681096,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"40602723","pmcid":null,"openalex_id":"https://openalex.org/W4411969364","authors":[],"funders":[{"funder_name":"Innovate UK","grant_id":"10041509","title":"FEAST (Food systems that support transitions to hEalthy And Sustainable dieTs"},{"funder_name":"Swiss State Secretariat for Education Research and Innovation","grant_id":"22.00156","title":null},{"funder_name":"European Commission","grant_id":"101060536","title":"FEAST"},{"funder_name":"Horizon Europe","grant_id":"","title":null},{"funder_name":"Spine Education and Research Institute","grant_id":"","title":null}],"total_grants":5,"fwci":1.8978,"citation_percentile":0.84753015,"influential_citations":0,"citation_trend":[{"year":2026,"count":2}],"oa_status":"hybrid","license":"cc-by","oa_locations":[{"url":"https://doi.org/10.1016/j.tjnut.2025.06.018","host_type":"journal"},{"url":"https://doi.org/10.1016/j.tjnut.2025.06.018","host_type":"publisher"},{"url":"https://api.elsevier.com/content/article/PII:S0022316625004031?httpAccept=text/xml","host_type":"publisher"},{"url":"https://api.elsevier.com/content/article/PII:S0022316625004031?httpAccept=text/plain","host_type":"publisher"},{"url":"https://pubmed.ncbi.nlm.nih.gov/40602723","host_type":"repository"},{"url":"https://hal.science/hal-05184615","host_type":"repository"},{"url":"https://www.sciencedirect.com/science/article/pii/S0022316625004031?CMX_ID=&SIS_ID=&dgcid=STMJ_220042_AUTH_SERV_PA&utm_acid=245472969&utm_campaign=STMJ_220042_AUTH_SERV_PA&utm_in=DM580037&utm_medium=email&utm_source=AC_","host_type":"repository"},{"url":"https://doi.org/10.1101/2025.02.07.25321862","host_type":""},{"url":"https://hal.science/hal-05184615v1/document","host_type":""},{"url":"https://hal.science/hal-05184615v1","host_type":""},{"url":"http://dx.doi.org/10.1016/j.tjnut.2025.06.018","host_type":""},{"url":"https://zenodo.org/records/17418926","host_type":""},{"url":"https://hdl.handle.net/11382/580233","host_type":""},{"url":"http://dx.doi.org/10.1016/J.TJNUT.2025.06.018","host_type":""}],"fields_of_study":["Agriculture Sustainability and Environmental Impact","Nutritional Studies and Diet","Consumer Attitudes and Food Labeling","0303 health sciences","03 medical and health sciences"],"mesh_terms":[],"keywords":["Environmental health","Scale (ratio)","Concurrent validity","Medicine","Gerontology","Psychometrics","Clinical psychology","Geography","Nutrition Surveys","Dietary Assessment","Healthy Eating","Sustainable Diet","Food Behaviors","Dietary Index","[SDV.AEN] Life Sciences [q-bio]/Food and Nutrition","[SDV.SPEE] Life Sciences [q-bio]/Santé publique et épidémiologie","sustainable dietdietary indexhealthy eatingdietary assessmentnutrition surveysfood behaviors","sustainable diet, dietary index, healthy eating, dietary assessment, nutrition surveys, food behaviors"],"sdg_mappings":[{"sdg_number":0,"sdg_label":"Zero hunger"}],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-09T02:28:31.833142Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
