（2023秋·江苏无锡·高三统考期末）Avoid the supermarket shelves piled with cheese, cupcakes and pies. That is the message of an analysis that found these items are the worst when looking at both nutritional and environmental impacts of thousands of food and drink products sold in the UK and Ireland. So far, most studies have focused on the environmental impact of goods such as beef or beans, rather than tofu and other products that shoppers often buy.

The team took the ingredients (成份) data from eight retailers (零售商), including major supermarkets Tesco and Sainsbury’s. However, precise figures on how much of each ingredient is in each product were only available for around a tenth of them. To estimate the rest, Clark and his colleagues trained an algorithm (算法) on the known products and used it to predict the composition of the unknown ones. Finally, the team linked all the ingredients to an existing database of environmental impacts, including emissions (排放), land use and water stress.
The results may come as no surprise: meat, fish and cheese products had highest environmental impact while fruit, vegetables, bread and sugary drink products had the lowest burden. Clark admits that none of this is exciting, given what we already knew from past research. “What is important is that you can start getting these impact estimates for products that people are purchasing, which then has a lot of effects,” he says.
