I did manage to read the article, and one of the "myths" it purports to de-bunk is that the quinine in tonic water prevents malaria.
I have to say I have lived in the tropics for 14 years, and drunk lots of gin and tonic and vodka and tonic during that time, and I have never had malaria.
Coincidence? Perhaps, but I am not prepared to risk it and will continue drinking G&Ts and VATs.
