气候变化正在威胁未来的全球粮食和营养安全。《巴黎协定》（2015年）规定将全球气温上升限制在1.5 °C，同时实现营养安全意味着彻底改革当前的粮食系统，以创建一个能够提供健康和可持续饮食的系统。为了实现这一目标，必须了解减缓气候变化的行动对营养的影响以及气候变化对粮食生产和食物营养成分的影响。人们普遍认为，畜牧业生产比农作物生产对环境的负担更大，因此建议减少肉类消费。这引发了一些部门对饮食中缺乏蛋白质的担忧，因此正在努力寻找蛋白质替代品。然而，在大多数高收入和中等收入国家，蛋白质摄入量远远超过膳食需求，即使从饮食中去除所有肉类，也会出现这种情况。在减少肉类时，应更多地注意微量营养素的减少。简单地少吃肉并不能保证更健康或更可持续的饮食。气候变化还将影响可生产的食物的种类、数量和营养质量。研究表明，气温升高和二氧化碳水平升高会降低一些主要作物的营养密度，这在低收入国家尤其令人关切。从气候变化的角度看营养问题，意味着要考虑任何气候行动对粮食和营养安全的潜在影响。在本文中，我们从跨学科的角度讨论这些问题。
Climate change is threatening future global food and nutrition security. Limiting the increase in global temperature to 1·5 °C set out in The Paris Agreement (2015) while achieving nutrient security means overhauling the current food system to create one that can deliver healthy and sustainable diets. To attain this, it is critical to understand the implications for nutrition of actions to mitigate climate change as well as the impacts of climate change on food production and the nutrient composition of foods. It is widely recognised that livestock production has a much greater environmental burden than crop production, and therefore advice is to reduce meat consumption. This has triggered concern in some sectors about a lack of protein in diets, which hence is driving efforts to find protein replacements. However, in most highand middle-income countries, protein intakes far exceed dietary requirements and it would even if all meat were removed from diets. Reduction in micronutrients should be given more attention when reducing meat. Simply eating less meat does not guarantee healthier or more sustainable diets. Climate change will also affect the type, amount and nutrient quality of food that can be produced. Studies have shown that increased temperature and elevated CO2 levels can reduce the nutrient density of some staple crops, which is of particular concern in low-income countries. Nutrition from a climate change perspective means considering the potential consequences of any climate action on food and nutrition security. In this paper, we discuss these issues from an interdisciplinary perspective.
