This book by Prof. John Yudkin, was published in 1972. It explains in detail, the effects of sugar on the human body. 1972!! It was ignored by the medical profession and rubbished by the manufacturers.
Prof Robert Lustig recently updated the original content, without changing its basic meaning. It has republished by Penguin as a paperback. Fascinating stuff!

I should add that Dr Yudkin makes a very cogent point about artificial sweeteners - although they may have been shown to be "bad for you" by tests on laboratory animals, the quantities we take in our tea, coffee etc are so small in comparison that there is very little likelihood of them doing you any real harm.
