What should we be scoffing if we want to help fight the climate crisis from our kitchens? The question has never been more important or confusing – here is a guide to help you get started

Was ever a word so misused as “sustainable”? “Healthy” comes close, and indeed the two are often bandied around together, in trite “good for you, good for the planet” taglines that often appear on foods which are anything but. The question of what we should eat to help combat climate change and environmental degradation has never been more important – nor so confusing. In July, the government will publish its National Food Strategy, based on a year-long independent review, which should shed some light on the matter. In the meantime, there are some foods which, with caveats, you can scoff with a clear conscience.

“Good eating starts at home, and one of the most important things we can do for the future of the planet is to minimise food miles – so our staples should be foods that can grow perfectly well in this country,” advises Patrick Holden, chief executive of the Sustainable Food Trust. Another basic principle is to do your best to understand the story behind what you’re eating – be it plant or animal: “If you know who produced your food, they are accountable to you, and more likely to care.”
