Almost 40 years ago, William Duffy published a book called Sugar Blues which argued that refined sugar is an addictive drug and profoundly damaging to health. While over 1.6 million copies have been printed since its release in 1975, a common criticism of the book has been that it lacked sufficient scientific support.

 

Today, William Duffy’s work is finding increasing support in the first-hand, peer-reviewed and published scientific literature itself. Not only is sugar drug-like in effect, but it may be more addictive than cocaine. Worse, many sugar-free synthetic sweeteners carry with them addictive properties and toxicities that are equal to, or may outweigh those of sugar.
