Here food choice was monitored over four weeks ( ~ 5,000 meals) in a UK university residence. Without students noticing, mathematically optimized menus achieved 30.7% and 6.3% reductions in carbon footprint and saturated fatty acid intake, respectively. This demonstrates the potential of strategic menu manipulation to benefit health and the environment, without the need for recipe changes. Menu manipulation is a promising strategy to increase environmental and health benefits of food choices. Drawing on data from a UK university residence, this study illustrates such potential.","PeriodicalId":94151,"journal":{"name":"Nature food","volume":"6 9","pages":"843-847"},"PeriodicalIF":21.9,"publicationDate":"2025-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s43016-025-01218-8.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144813042","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Transportation-to-market of Canadian crops is proportionately important, but related emissions are often more than offset by low production-related emissions. In extreme cases, Canadian crops could be shipped to western European markets an additional 17 times before their carbon footprint would break even with crops grown in Europe. Greenhouse gas emissions of major commodity field crops are of increasing interest to diverse stakeholders. A carbon footprint analysis following the ISO 14067 standard reveals key drivers of, and differences in, emissions for selected field crop production and transport to market between Canada and other countries.","PeriodicalId":94151,"journal":{"name":"Nature food","volume":"6 8","pages":"757-761"},"PeriodicalIF":21.9,"publicationDate":"2025-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s43016-025-01212-0.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144778485","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Agricultural lime can be used to alleviate production constraints associated with soil acidity, but lime is not widely available in the region, and it is unclear if applying it would be profitable. Using lime requirement models and crop yield responses to soil acidity modelled as plateau–linear decay functions, we estimated the profitability of acid soil remediation through liming. Crop yield loss to soil acidity occurs on 32.7 Mha, or 23% of sub-Saharan Africa’s cropland. The burden of acid soils is US$6.0 billion (6% of the current production value), and 75% of that could be profitably alleviated. Under prevailing conditions, liming would be profitable in the year of application on 6.2 Mha (with an average profitability of US$278 ha−1) and on 8.8 Mha when lime’s long-term effect is considered. Intensification of crop production and lower relative lime/output prices could make liming profitable on more cropland. Soil acidity constrains agricultural productivity in a large proportion of sub-Saharan Africa’s croplands. This study estimates the location- and crop-specific amounts of lime required to remediate acid soils, taking into account the profitability and returns on investment of liming in the year of application and beyond.","PeriodicalId":94151,"journal":{"name":"Nature food","volume":"6 8","pages":"799-808"},"PeriodicalIF":21.9,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144701531","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
