Key takeaways

  • Sugar Blues belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Sugar Blues to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Sugar Blues from memory before moving on to harder problems.

Reference excerpt

Sugar Blues is a book by William Dufty that was released in 1975 and has become a dietary classic. According to the publishers, over 1.6 million copies have been printed. Dufty uses the narrative form to delve into the history of sugar and history of medicine. He mentions whistle blowers, such as Semmelweiss, to remind readers of the discontinuities in standard science. He also delves into the history of Cuba, history of slavery, history of tobacco and tobacco curing to present the sociology of sugar. The status of sugar, as a product of refining, was compared to drugs:

Heroin is nothing but a chemical. They take the juice of the poppy and they refine it into opium and then they refine it to morphine and finally to heroin. Sugar is nothing but a chemical. They take the juice of the cane or the beet and then refine it to molasses and then they refine it to brown sugar and finally to strange white crystals. (page 22) Later, the euphemism, "made from natural ingredients", is cited as equally applicable to heroin and sugar. (page 148)

Contents The book has 14 chapters, 78 references, five pages of notes, and a 10-page index. The book reviews the history of the world from the point of view of sugar, sounding the alarm of its deleterious and debilitating effects. The chapters are:

It Is Necessary to be Personal Gloria Swanson alerted Dufty to sugar's threat to health. The Mark of Cane "Benjamin Delessert found a way to prepare the lowly Babylonian beet into a new kind of sugar loaf at Plessy in 1812. Napoleon awarded him the Legion of Honour. Napoleon ordered sugar beets planted everywhere in France, an imperial factory was established for refining, scholarships were granted to schools for sugar beet crafts; 500 licences were created for sugar refineries. By the very next year, Napoleon had achieved the herculean feat of producing eight million pounds of sugar from homegrown beets. When Napoleonic armies set out for Moscow, their sugar rations were insured. Like the Moors before them, they were turned back while traveling north. The mighty French army, in the unaccustomed climate, had met their match and more, including the armies of a backward people who had not yet accustomed themselves to sugar in their tea." (page 38) How We Got Here from There "Arab and Jewish physicians used sugar carefully in minuscule amounts, adding it to their prescriptions with great care. It was a brain boggler. It could cause the human body and brain to run the gamut in no time at all from exhaustion to hallucination." (page 46) Maurice Mességué led Dufty through his garden of healing herbs. (pages 56–9) In Sugar We Trust Linus Pauling and Thomas Szasz are cited on the threat to mental well-being. Blame It on the Bees Diabetes mellitus suffering increased as sugar usage grew. Nyoiti Sakurazawa found the cure in traditional Japanese eating, and in 1971 research confirmed that a diet high in carbohydrates, ironically, improved human capacity to moderate blood sugar level. From the Nipple to the Needle Describes diabetic hypoglycemia with a reference to the film Men in White (1934) and gives a narrative of "George's" insulin dependency. Of Cabbages and Kings Thomas Willis warned of scurvy from sugar and James Lind suggested a cure. How to Complicate Simplicity The Engelberg machine debilitates the potential nutrition from grains. Dead Dogs and Englishmen Why sugar calories are empty calories. Codes of Honesty Harvey Wiley made the mistake of mentioning saccharin to Theodore Roosevelt. What the Specialists Say Peptic ulcers were discussed on the David Susskind Show, but not John Yudkin's theory. Reach for a Lucky Instead of a Sweet? Usually sugar in the mouth and on the enamel of teeth is said to feed bacteria that can cause dental caries. Experimenters have shown that sugar acts inside the enamel as well, constricting flows in the dentin. This metabolic effect of sugar in the diet inhibits preservation of enamel by supply from tooth pulp, through dentin, to enamel. Kicking The sugar-laced diet is a form of substance abuse and must be dealt with as an addiction. Recommendations are given for both individuals and families. "In kicking sugar, the most helpful extra hint I can give you is the one that worked for me. Kick red meat at the same time...Meat (which is masculine yang) sets up a powerful yen in your system to be balanced with its opposite – something very sweet and feminine and yin, like fruit and sugar." (page 209) Soup to Nuts As an antidote to Fannie Farmer’s cookbooks, Dufty offered an introduction to the use of tamari, pressed salad, buckwheat, sprouting, free-range eggs, garlic, tahini, brown rice, dried fruit, umeboshi, compote, root vegetables, crepes, walnuts, and chestnuts.

Mentions Dufty's wife, Gloria Swanson, traveled the United States to promote the book in 1975. A study of depression avoidance included Sugar Blues as one of its "books which treat either primarily or in particular chapters the role of nutritional and dietary factors in the promotion of mental well-being and prevention of disorder...on the role of diet in particular disorders...functional hypoglycemia (Duffy [sic] 1975)." John Lennon’s personal assistant Frederic Seaman described Lennon’s diet in the book The Last Days of John Lennon (1991). When Seaman started in the job, Dufty’s book loomed large:

Punctuating his speech with slight hand gestures, he then launched into a passionate lecture on the dangers of sugar and told me to keep an eye out for a book entitled Sugar Blues at Better Nature, the local health food store where I would buy most of his food. He extolled the book by Gloria Swanson’s former [sic] husband William Duffy [sic], because it exposed sugar as a "poison". He asserted that he did not want Sean to become a "sugar junkie", like so many other American kids who grew up to be overweight, pimply teenagers. A food science educator listed Sugar Blues as a sample text to stimulate critical thinking necessary to become a food scientist:

Worked examples

Example 1 — a first encounter with Sugar Blues

Start with the simplest possible case. Write down what Sugar Blues claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Sugar Blues before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Sugar Blues ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Sugar Blues

In research
Sugar Blues appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Sugar Blues in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Sugar Blues is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1975 non-fiction books, Books about food and drink, Chilton Company books, so understanding it makes those chapters shorter.
In everyday life
Look for Sugar Blues outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
