This paper reviews the current literature around the environmental impacts of dietary recommendations. The focus of the review is on collating evidence relating to environmental impacts of the dietary advice found in the World Health Organisation guidelines, and environmental impact literature: reducing the consumption of fat, reducing the consumption of meat-based protein and animal-based foods, and increasing the consumption of fruit and vegetables. The environmental impact of reducing dietary fat intake is unclear, although reducing consumption of the food category of edible fats and oils appears to have little impact. However most, but not all, studies support environmental benefits of a reduced consumption of animal-based foods and increased consumption of fruit and vegetables. In general, it appears that adhering to dietary guidelines reduces impact on the environment, but further study is required to examine the environmental impacts of animal-based foods, and fruit and vegetable intake in depth.
本文综述了有关饮食建议对环境影响的现有文献。本综述的重点是整理与世界卫生组织指南中发现的饮食建议的环境影响以及环境影响文献有关的证据：减少脂肪摄入、减少基于肉类的蛋白质和动物食品的摄入，以及增加水果和蔬菜的摄入。减少膳食脂肪摄入的环境影响尚不清楚，尽管减少食用脂肪和油这一食物类别的摄入似乎影响不大。然而，大多数（但不是全部）研究支持减少动物食品的摄入和增加水果和蔬菜的摄入对环境有益。总的来说，遵循饮食指南似乎可以减少对环境的影响，但需要进一步研究以深入探讨动物食品以及水果和蔬菜摄入对环境的影响。
