The World Index for Sustainability and Health (WISH) measured adherence to the EAT-Lancet reference diet, reflecting dietary quality aligned with planetary health principles. Diet-related environmental indicators (greenhouse gas emissions [GHGE] and land use [LU]) were estimated using the SHARP-Indicators database. BMI (measured) z-scores were classified according to WHO criteria. Dietary patterns (DP) were derived using latent class analysis. Simulations aligned current dietary intake with the EAT-Lancet reference diet. The potential to prevent obesity cases was estimated by Potential Impact Fractions (PIF).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Overall, current diets are not aligned with the Planetary Health Diet. Among children, reducing the consumption of eggs, meats, fish, and soft drinks improved WISH scores and decreased environmental indicators. For adolescents, the greatest reductions of these indicators were achieved by reducing dairy and red meat. The scenario that led to the largest significant reduction in obesity cases involved a shift towards a plant-based dietary pattern (PIF\u2009=\u20090.7% children, 0.2% adolescents), which also increased environmental impact (with mean GHGE increasing from 3.9 to 4.1\u00a0kg CO\n                      <jats:sub>2<\/jats:sub>\n                      -eq), as it replaced diets already low in animal products with a plant-based pattern of greater overall food intake.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>To effectively enhance adherence to the EAT-Lancet diet, promoting plant-based foods should be coupled with reductions in dairy, meat, soft drinks, and total dietary quantity.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1007\/s00394-026-04069-6","type":"journal-article","created":{"date-parts":[[2026,7,21]],"date-time":"2026-07-21T10:36:24Z","timestamp":1784630184000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Modelling EAT-lancet dietary patterns scenarios: effects on environmental and health metrics in children and adolescents"],"prefix":"10.1007","volume":"65","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9738-704X","authenticated-orcid":false,"given":"Beatriz","family":"Teixeira","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cl\u00e1udia","family":"Afonso","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Catarina","family":"Carvalho","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Duarte","family":"Torres","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carla","family":"Lopes","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Milton","family":"Severo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andreia","family":"Oliveira","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2026,7,21]]},"reference":[{"issue":"26","key":"4069_CR1","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.2219272120","volume":"120","author":"S Biesbroek","year":"2023","unstructured":"Biesbroek S, Kok FJ, Tufford AR, Bloem MW, Darmon N, Drewnowski A, Fan S, Fanzo J, Gordon LJ, Hu FB, L\u00e4hteenm\u00e4ki L, Nnam N, Ridoutt BG, Rivera J, Swinburn B, Veer PV (2023) Toward healthy and sustainable diets for the 21st century: importance of sociocultural and economic considerations.
