What do sweeteners do to our bodies? We force feed James cups of sweetened tea and find out with nutrition scientist Dr Sarah Berry from King’s College London.

And Rohin Francis gets frustrated at the shonky claims being made by health podcasts (not this one, of course, you’re totally in the right place).
