But the English had notoriously bad teeth for a very long time because of so much sugar in tea.
There is a very long story, that in a way encapsulates early 19th-c English history and the "Industrial Revolution," along with mass starvation in India and opium addiction in China, behind this factoid on tea, sugar, & British workers. I read it recently but can't remember my source. I'll try to find it.
P.S. Distantly & indirectly related is a British folk song, "He watered the workers' beer."
