The lives of post-harvest fisheries workers, over half of them women, are deeply affected by these technologies, but their equity and equality outcomes are poorly understood. This systematic review synthesizes evidence of post-harvest aquatic food processing technology outcomes, showing that persistent inequalities in social structure and norms disadvantage women across a range of technologies, both traditional and improved, especially regarding control over resources. We found that improved technologies bring enhanced productivity and possibly income for workers, yet contracts are often precarious due to pre-existing social inequities. While power and control of resources is more unequal in factory settings, it is not necessarily equal in traditional contexts either, despite offering greater flexibility. More rigorous comparative research, including voices of diverse actors, is key to understanding the impacts of different technologies on gender equality and social justice and inform policymaking.</p>","PeriodicalId":94151,"journal":{"name":"Nature food","volume":null,"pages":null},"PeriodicalIF":23.6,"publicationDate":"2024-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142083016","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}

However, current production technologies result in low yields, leading to economic projections that prohibit cultivated meat scalability. Here we use tangential flow filtration for continuous manufacturing of cultivated meat to produce biomass of up to 130 × 106 cells per ml, corresponding to yields of 43% w/v and multiple harvests for over 20 days. Continuous manufacturing was carried out in an animal-component-free culture medium for US$0.63 l−1 that supports the long-term, high density culture of chicken cells. Using this empirical data, we conducted a techno-economic analysis for a theoretical production facility of 50,000 l, showing that the cost of cultivated chicken can drop to within the range of organic chicken at US$6.2 lb−1 by using perfusion technology. Whereas other variables would also affect actual market prices, continuous manufacturing can offer cost reductions for scaling up cultivated meat production. Data from tangential flow filtration experiments using cell culture medium without animal products are used to estimate the costs of scaled-up, continuous cultivated chicken manufacturing.","PeriodicalId":94151,"journal":{"name":"Nature food","volume":null,"pages":null},"PeriodicalIF":23.6,"publicationDate":"2024-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142013810","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}

Here we compare the environmental impact and cost of diets based on the HSDG 2023, current diets and the Mexican-adapted EAT healthy reference diet. Diets following HSDG 2023 are 21% less expensive, require 30% less land to be produced and have 34% less carbon emissions than current diets—particularly in Mexico City and other urban areas with higher prevalence of Westernized diets. This is driven by reduced animal-source food, especially red meat, and ultra-processed foods. In south–rural areas, the water footprint and cost of diets following HSDG 2023 were higher than those of current diets owing to increased intake of nuts, fruits and vegetables not offset by lower meat consumption (which is already close to recommendations). Diet environmental impact and cost could be further reduced with the Mexican-adapted EAT healthy reference diet compared with the HSDG 2023. Sustainability is increasingly integrated into national food-based dietary guidelines, but how and to what effect requires investigation. This study analyses the costs and environmental impact of the 2023 Mexican Healthy and Sustainable Dietary Guidelines (HSDG) relative to current diets and the Mexican-adapted EAT healthy reference diet.","PeriodicalId":94151,"journal":{"name":"Nature food","volume":null,"pages":null},"PeriodicalIF":23.6,"publicationDate":"2024-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141895366","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}
