Environmental impact of four meals with different protein sources: Case studies in Spain and Sweden

摘要: The production of food protein has a considerable impact on the environment. This paper investigates potential environmental benefits introducing more grain legumes in human nutrition. Four meals with different amounts soybeans or peas (either used as feed for pork directly consumed) were analysed using life cycle assessment methodology. results this analysis demonstrate that it is environmentally favourable to replace meat peas. In particular, addition nutrition potentially aids reduction global warming, eutrophication, acidification, and land use; however, terms energy use, completely vegetarian pea burger meal requires same amount other meat-containing meals. Feeding pigs European-produced instead imported soybeans, partial replacement (10%) protein, failed reduce meal. summary, can be considered ‘green’, but there remains significant need energy-efficient processing products.
