摘要

全球范围内的食品和饮食对环境有着重大影响。虽然人们对健康、可持续饮食的基本原则达成了广泛共识,但对其在实践中可能意味着什么的解释却存在广泛争议。误解很常见,包括鸡蛋对环境的影响及其在健康、可持续饮食中的地位。在报告食物和饮食对环境的潜在影响时,鸡蛋通常与牛肉、羊肉、家禽、肉类和乳制品等其他动物蛋白分类。然而,向更环保的饮食转变需要清楚地了解这种饮食应该基于的证据基础。这篇综述评估了科学报告和同行评审文章,这些报告和文章从温室气体排放、土地和水的使用方面评估了鸡蛋对环境的影响,并将鸡蛋的影响与其他动植物蛋白质的影响进行了比较。这一综述表明,鸡蛋比其他动物蛋白质,特别是牛肉,对碳、土地和水的使用更少,只比大多数植物蛋白质略多。鸡蛋是一种营养丰富、方便且相对便宜的食物,传统上在英国和全球的饮食中都占有重要地位。因此,重要的是要了解它们在环境影响方面的适用性,并为更健康、更可持续的饮食模式提供建议。

The importance of eggs in an environmentally sustainable diet.

Food and diet globally have a significant environmental impact. Whilst there is broad agreement on the principles underpinning a healthy, sustainable diet, the interpretation of what it might mean in practice is widely debated. Misconceptions are common, including around the environmental impact of eggs and their place in a healthy, sustainable diet. Eggs are often categorised with other animal proteins such as beef, lamb, poultry, meat and dairy when reporting on the potential environmental impact of food and diets. However, the shift towards more planet-friendly diets demands a clear understanding of the evidence base on which such a diet should be based. This review evaluates scientific reports and peer-reviewed articles that have evaluated the environmental impact of hens' eggs in terms of greenhouse gas emissions (GHGEs), and land and water use and compared the impacts of eggs with those of other animal and plant proteins. This overview shows that eggs are responsible for less carbon, land and water use than other animal proteins, particularly beef and only slightly more than most plant proteins. Eggs are a nutritious, convenient and relatively inexpensive food, which traditionally has had an important place in the diet both in the United Kingdom and globally. It is therefore important to understand where they fit in terms of environmental impact and into advice on healthier, more sustainable dietary patterns.
