米国の大規模調査データを用いて、7つの食事パターン指標と慢性疾患、死亡率、食事由来の温室効果ガス排出（GHGE）との関連を分析。健康的な食事パターンほどGHGEが低く、健康面でも良い結果を示し、ヒトの健康と環境面での共便益が確認された。
English
This study analyzed data from 27,517 U.S. adults (NHANES 2005-2018) to examine associations of seven dietary indices with chronic diseases, mortality, and diet-related greenhouse gas emissions (GHGE). Higher adherence to healthy dietary patterns was associated with lower prevalence of major chronic diseases (12-15% lower), reduced all-cause mortality (up to 48% lower), and lower diet-related GHGE (up to 1.84 kgCO2e/person/day less). The findings highlight co-benefits for human health and environmental sustainability.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では、食生活のGHG排出量削減は食品産業や家庭のScope3排出に直結する。本研究の結果は、日本の食品企業や政策立案者が健康的で低炭素な食事パターンを推進する根拠を提供する。
In the global GX context
This paper provides empirical evidence linking dietary patterns to both health outcomes and greenhouse gas emissions. For global GX context, it supports incorporating dietary shifts into climate mitigation strategies (e.g., national dietary guidelines, corporate Scope 3 food emissions reduction). It also demonstrates a methodology for estimating diet-related GHGE using NHANES data.
👥 読者別の含意
🔬研究者:This paper offers a methodological framework for linking dietary intake data to GHG emissions databases, and provides comparative evidence across multiple dietary indices.
🏢実務担当者:Corporate sustainability teams in food/agriculture can use these findings to design product portfolios and menu options that lower carbon footprint while promoting health.
🏛政策担当者:Policymakers can use this evidence to promote dietary guidelines that align climate and health objectives.
📄 Abstract（原文）
299 Background: Dietary patterns directly influence both human health and environmental attributes, yet comparative evidence linking the duo-impacts of different dietary patterns to health outcomes and environment remains limited. Objectives: This study aimed to examine associations of multiple dietary indices with major chronic diseases (MCDs) (including cancer, diabetes, and cardiovascular diseases), all-cause mortality, and dietary-related greenhouse gas emissions (GHGE) among United States (US) adults. Methods: We analysed data from 27,517 US adults who participated in the National Health and Nutrition Examination Survey (NHANES) 2005–2018 and provided their disease information and two-day 24-hour diet recalls. Seven dietary patterns including the Healthy Eating Index-2020 (HEI-2020), Alternate Healthy Eating Index (AHEI), Dietary Approaches to Stop Hypertension (DASH), alternate Mediterranean Diet score (aMED), Planetary Health Diet Index (PHDI), American Cancer Society 2020 diet score (ACS2020), and the Dietary Index for Gut Microbiota (DI-GM) were assessed. Dietary-related greenhouse gas emissions were estimated by linking individual food intakes to dataFRIENDS, a food environmental impact database. All-cause mortality was obtained by linkage to the National Centre for Health Statistics mortality files up to 2019. Results: For MCDs, compared with those in the lowest quintile, participants in the highest quintile of HEI-2020, AHEI, DASH, aMED, and ACS2020 were significantly associated with 12-15% lower prevalence of MCDs. No significant associations were observed between seven dietary scores and cancer in this cross-sectional analysis. For all-cause mortality, all studied diet patterns showed strong inverse associations with risk of death, especially PHDI and DI-GM (about 48% lower risk of death in Q5 vs Q1). For environmental impact, higher dietary scores were associated with lower diet-related GHGE, especially ASC2020 and PHDI (1.84 and 1.31 kgCO2e/person/day lower in Q5 vs Q1, respectively). Conclusions: Overall, higher adherence to healthy dietary patterns was associated not only with better health outcomes but also lower diet-related GHG emissions, suggesting co-benefits for human health and environmental sustainability.
