Evaluating the water footprint and nutritional quality of takeaway dishes for selected large cities in China

Abstract

The takeaway food and delivery market is developing rapidly in China, raising concerns about the impacts of takeaway dishes on both health and the environment. Here, we compare the environmental impact and nutritional performance of 32 popular takeaway dishes, which stem from the top 10 best-selling takeaway dishes in 10 large cities in China. We select water footprint and water scarcity footprint indicators to represent the environmental impact, and the Food Compass Score to measure nutritional quality. Our results show that 24 out of 32 takeaway dishes contains meat, which has a higher water footprint. The inhabitants of water stressed Chinese cities, mainly located in northern China, tend to favor meat dishes, resulting in a larger water scarcity footprint. The results also highlight the lower nutrition quality of the majority of takeaway dishes, with only three takeaway dishes meeting acceptable environmental and nutritional standards. Our study highlights the importance of analyzing dishes rather than individual foods, which can facilitate sustainable dietary choices for consumers.
