‘We must change our diet. The planet can’t support billions of meat-eaters,’ said Sir David Attenborough in his recent Netflix documentary, A Life on Our Planet. More and more people are shifting to plant-based diets, believing they are better for their health and the planet.

But what does science actually say on the impacts of vegetarianism and veganism? Do we miss out on anything nutritionally when we cut out the meat? Are all plant-based diets equally good for the environment, or are there shades of green in green cuisine? And how can we make more responsible and healthy decisions around what we eat without compromising our enjoyment of food?

At this Imperial Lates Online discussion, we bring together a dietician, a climate scientist and a chef and food writer to address all these question and many more. So if you are thinking about going veggie this Christmas, or if your New Year’s resolution might be to cut down on the meat, join us to put your questions to an expert panel featuring:

• Pietro Salvi, Climate scientist and co-chair of the Vegetarian society at Imperial  

• Aygul Dagbasi, Dietician in the Department of Metabolism, Digestion and Reproduction at Imperial 

• Ching-He Huang, TV Chef & Food Writer
