Sugar Blues is a book by William Dufty that was released in 1975 and became a commercial success. According to the publishers, over 1.6 million copies have been printed.[1]

In the book, Dufty makes the case that sugar is an addictive drug, that it is extremely harmful to the human body, and that the sugar industry conspires to keep Americans addicted to sugar.


The book's central argument is that consumption of refined sugar is unnatural and damaging to human health, causing major differences in physical and mental well-being. Dufty even goes so far as to suggest that eliminating refined sugar from the diet of those institutionalized for mental illness could be an effective treatment for some. The sugar industry is criticized for misrepresenting the health and safety data of its products.


Dufty's wife, Gloria Swanson, traveled the United States and helped to promote the book in 1975. John Lennon was a strong supporter of the book.[2]

A food science educator listed Sugar Blues as a sample text to stimulate critical thinking necessary to become a food scientist:

Processed foods, artificial ingredients, chemicals in our foods, and unnatural foods have long been the target of books, [six listed including Dufty 1975] but there seems to be limited understanding of food science...A critical reading of one or more of these sources or alternatives is recommended to see if there is what we can learn as we practice our profession and how to respond to criticism that we may receive.[3]


Censorship analyst Heather Hendershot and historian Mark Pendergrast have criticized the book for comparing sugar to drugs and suggesting its role in a variety of illnesses including bubonic plague.[4][5]

Scientist Michael E. Oakes has also commented on the book.[6]
