目的:对挪威成年人的饮食环境影响进行了六个环境影响类别的估计。此外,评估了符合挪威基于食物的饮食指南(FBDG)和EAT-Lancet参考饮食的情景饮食的环境效益.
方法:根据国家饮食监测调查(Norkost3)的24小时饮食回忆数据,对挪威成年人的当前饮食进行了估算。对情景饮食进行建模以代表挪威FBDG和EAT-Lancet健康参考饮食。饮食对全球变暖潜力的环境影响,淡水和海洋富营养化,陆地酸化,使用代表挪威市场的环境影响数据,对当前和情景饮食的水使用,转换和土地使用进行了估算。影响与性别/教育程度之间的显着关联被评估为P<0·05。
方法:挪威。
方法:参加Norkost3调查(2010-2011)的18-70岁成年人(n=1787)。
结果:环境影响因性别和受教育程度而异。挪威饮食对环境影响最大的食物群体是肉类,乳制品,饮料,谷物和复合菜肴。与目前的挪威饮食相比,FBDG情景将影响从2%(淡水富营养化)减少到32%(用水),而EAT-Lancet情景将影响从7%(海洋富营养化)减少到61%(土地利用)。EAT-Lancet方案比FBDG方案减少了3-48%的影响。
结论:挪威FBDG,虽然不像EAT-Lancet参考饮食那样环保,仍然可以成为减轻挪威饮食环境负担的重要工具。
OBJECTIVE: Dietary environmental impact in a Norwegian adult population was estimated for six environmental impact categories. Moreover, environmental benefits of scenario diets complying with the Norwegian Food-Based Dietary
Guidelines (FBDG) and the EAT-Lancet reference diet were assessed.
METHODS: The current diet of Norwegian adults was estimated according to 24-h dietary recall data from a national dietary surveillance survey (Norkost 3). Scenario diets were modelled to represent the Norwegian FBDG and the EAT-Lancet healthy reference diet. Dietary environmental impact in terms of global warming potential, freshwater and marine eutrophication, terrestrial acidification, water use and transformation and use of land was estimated for the current and scenario diets using environmental impact data representative of the Norwegian market. Significant associations between impact and gender/educational attainment were assessed at P < 0·05.
METHODS: Norway.
METHODS: Adults (n=1787) aged 18-70 years who participated in the Norkost 3 survey (2010-2011).
RESULTS: Environmental impact varied significantly by gender and educational attainment. The food groups contributing most to environmental impact of Norwegian diets were meat, dairy, beverages, grains and composite dishes. Compared with the current Norwegian diet, the FBDG scenario reduced impacts from 2 % (freshwater eutrophication) to 32 % (water use), while the EAT-Lancet scenario reduced impacts from 7 % (marine eutrophication) to 61 % (land use). The EAT-Lancet scenario resulted in 3-48 % larger reductions in impact than the FBDG scenario.
CONCLUSIONS: The Norwegian FBDG, while not as environmentally friendly as the EAT-Lancet reference diet, can still be an important tool in lessening environmental burden of Norwegian diets.
