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.
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 < 0·05.
Norway.
Adults (=1787) aged 18-70 years who participated in the Norkost 3 survey (2010-2011).
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.
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.
估计了挪威成年人中六种环境影响类别下的饮食环境影响。此外，还评估了符合挪威食物为基础的饮食指南（FBDG）和 EAT-柳叶刀参考饮食的情景饮食的环境效益。
根据国家饮食监测调查（Norkost 3）的 24 小时饮食回忆数据，估计了挪威成年人的当前饮食。为了代表挪威 FBDG 和 EAT-柳叶刀健康参考饮食，模拟了情景饮食。使用代表挪威市场的环境影响数据，估算了当前和情景饮食的全球变暖潜势、淡水和海洋富营养化、陆地酸化、水利用和转化以及土地利用方面的饮食环境影响。在 < 0·05 水平上评估了影响与性别/教育程度之间的显著关联。
挪威。
参加 Norkost 3 调查（2010-2011 年）的年龄在 18-70 岁的成年人（1787 人）。
环境影响因性别和教育程度而异。对挪威饮食环境影响贡献最大的食物组是肉类、奶制品、饮料、谷物和综合菜肴。与当前的挪威饮食相比，FBDG 情景减少了 2%（淡水富营养化）至 32%（水利用）的影响，而 EAT-柳叶刀情景减少了 7%（海洋富营养化）至 61%（土地利用）的影响。EAT-柳叶刀情景的影响减少幅度比 FBDG 情景大 3-48%。
尽管挪威 FBDG 不如 EAT-柳叶刀参考饮食环保，但它仍然是减轻挪威饮食环境负担的重要工具。
