For instance, in France, FBDG recommend consuming no more than 500 g of red meat and 150 g of processed meat per week. This study uses modeling to investigate the range of greenhouse gas emissions (GHGe) that can be achieved under FBDG compliance.</p><p><strong>Methods: </strong>The study analyzed data collected in 2014 from 29,413 NutriNet-Santé participants to assess their adherence to the French FBDG. GHGe, cumulative energy demand (CED), and land occupation (LO) for organic and conventional foods were obtained from the DIALECTE database. First, diets adequate in nutrients, culturally acceptable, and consistent with FBDG were modeled while minimizing or maximizing GHGe. Then, the spectrum of diets between minimum and maximum GHGe was explored while minimizing total departure from the observed diet with a gradual constraint on GHGE using the same other constraints. Environmental, economic (monetary cost), nutritional, and health criteria (Health risk score denoting long-term risk for health associated with diet) were then estimated for each diet.</p><p><strong>Results: </strong>The average observed adequacy to FBDG was low (19%, SD = 25%) and GHGe were 4.34 (SD = 2.7%) kgCO2eq/d. Under nutritional, acceptability and FBDG constraints, the GHGe range of the diets varied from 1.16 to 6.99 kgCO2eq/d, depending up to ∼ 85% on the level of meat consumption. A similar shape was observed for CED, LO, and Health Risk Score, but costs were consistently higher than in the observed diet, and exhibited a U-shape. A greater proportion of organic foods was noted in the lower-emission diet; however, this proportion was low in the meat-rich, high-emission diet. At isoenergetic diets, the diet with the lowest emissions had more vegetables, whole grains, and plant-based substitutes.</p><p><strong>Conclusions: </strong>While French dietary guidelines contribute, on average, to mitigating climate change and promoting health, this study emphasizes levers in recommended food consumption to more efficiently reduce diets' GHGe and points to total meat as the critical issue to better account for pressure on climate change. Other environmental pressures should also be taken into account when designing dietary guidelines.</p>","PeriodicalId":50336,"journal":{"name":"International Journal of Behavioral Nutrition and Physical Activity","volume":"22 1","pages":"95"},"PeriodicalIF":5.6,"publicationDate":"2025-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12239361/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144602091","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the third phase, a combined nudge was applied, adding a verbal recommendation to the order nudge. Data from 6,575 inpatients (mean age: 57.3 ± 18.7; 50.6% female) covering 26,949 meal choices were analyzed using logistic regression and generalized linear modeling.</p><p><strong>Results: </strong>Independent of nudging, female sex and younger age predicted plant-based menu choices (p <. 001, respectively). Controlling for the effects of sex and age, patients were nearly twice as likely to choose the plant-based menu during both intervention phases compared to baseline (order nudge: OR = 1.95; 95% CI [1.55-2.45]; p <.001; combined nudge: OR = 1.95; 95% CI, [1.56-2.44]; p <.001). However, there was no significant difference in plant-based menu selection between the two nudges (OR = 1.00; 95% CI [0.80-1.25]; p =.992). Subgroup analyses further revealed that both women and men as well as middle-aged (36-64 years) and older adults (≥ 65 years), but not younger adults (18-35), were significantly more likely to select plant-based menus during the interventions compared to baseline. Among both sexes and across all age groups, no differences in plant-based meal selection were found between the order and the combined nudge (all p >.001).</p><p><strong>Conclusion: </strong>Centrally implemented nudging is a simple and effective strategy that can increase patients' choice of plant-based menus, which in turn may promote patient health and contribute to positive environmental outcomes.</p><p><strong>Trial registration: </strong>DRKS00036763.
