Back in 2012 the BBC aired the Addicted to Pleasure series of documentaries, of which Sugar was the first episode.
This is the way the BBC introduced the documentary:
"Revealing the rich and controversial past of sugar, alcohol, tobacco and opium, Hollywood actor Brian Cox embarks on a thought-provoking journey to uncover how the commercial exploitation of these products hooked the rest of the world on an appetite for a good time.
In this first episode, Brian wants to find out why (like millions of other Brits), he is a diabetic. Starting in Barbados, from which sugar cane fuelled a consumer revolution, Brian discovers how the British acquired a 'sweet tooth' and why today, this has led to epidemic levels of diabetes, obesity and even addiction to sugar."
