Social factors are discussed. For example, there are comparisons of the tea culture of England with that of Japan and comparisons of both with the coffee culture of the United States. The duality of the culture of coffee (as in coffee houses) and the culture of tea (as in tea shops, tea gardens, and afternoon tea) is emphasized and illustrated with a list of more than 30 word pairs. One word in each pair is labeled the "coffee aspect" and the other the "tea aspect." The list of coffee aspects starts with "male," "boisterous," and "bohemian" and ends with "Balzac," whereas the list of tea aspects starts with "female," "decorous," and "conventional" and ends with "Proust." Cola beverages are said not to have a long enough history to have features as well differentiated as these, but they do have distinctive associations, such as "youth, high energy, America, pop culture, and `good clean fun."' Although the authors emphasize that all these popular beverages contain the drug caffeine, the diversity of the cultures associated with the different beverages suggests that caffeine is only one factor leading to their consumption.
True to its title, the book has little to say about alcohol, but the authors do make the important point that, at least in Europe and North America and at least in the large towns, raw water was not fit to drink until late in the 19th century. The increase in tea and coffee drinking offered an alternative to the usual beverages: beer, gin, and rum. The authors credibly associate this shift with a decrease in alcohol intake, to the benefit of society.
In the second half of the book, the nature of the story changes. The urbane historical perspective gives way to more recent concerns, including a discussion of what might be called huckstering by purveyors of caffeine products. Almost the final third of the book is devoted to the chemistry, pharmacology, and medical aspects of caffeine. I do not think that in a book of this size it is possible to present enough of an understanding for readers to reach their own conclusions on adequate grounds about the health and safety aspects of caffeine, and in many instances the original sources must be scrutinized for the adequacy of the evidence. In addition, there are errors. For example, a woman is said to have had a serum caffeine concentration of almost 300 mg per milliliter, which is many times the solubility of caffeine. Readers can remain confused, they can accept the often implicit conclusions of the writers, or they can opt out and simply trust the Food and Drug Administration (FDA).
A number of minor matters follow. Pure caffeine is variously described as "highly toxic" or "extremely toxic." An agent that can be ingested in amounts of several grams with relative impunity would not customarily be considered very toxic. A number of common foods -- dry mustard, horseradish, or cayenne pepper, for instance -- would not go down well as boluses of several grams. The poison of the puffer fish, whose flesh is eaten in Japan, is highly toxic, being hazardous in quantities thousands of times smaller than ordinarily consumed quantities of caffeine.
Finally, the authors aver that the International Life Sciences Institute (ILSI) was founded to help forestall efforts to regulate caffeine. But the FDA was regulating caffeine long before the ILSI was formed. The Caffeine Technical Committee of the ILSI was formed by interested companies to sponsor research on questions on caffeine raised by the FDA and others. It is prohibited from lobbying.

This review is from: The World of Caffeine: The Science and Culture of the World's Most Popular Drug (Hardcover)
"The World of Caffeine: The Science and Culture of the World's Most Popular Drug" is the best book found on the subject. No other book even comes close to the scope of this important topic covered in such magnificent detail! Nearly 400 pages in length encompassing seventeen highly informative chapters separated into five distinct parts, this jewel of nonfiction work by authors Bennett Alan Weinberg and Bonnie K. Bealer is sure to mark it's place in history as the best in its class.Part I, "Caffeine in History" tells everything you could possibly want to know about this powerful, world's most popular drug, from the Arabian Origins to its refined, almost religious use in Europe, blending into Part II. Part III discusses the role of caffeine from a cultural standpoint and works its way into Part IV, "The Natural History of Caffeine." Of particular interest to me is Part V, "Caffeine and Health," specifically Chapter 15, "Caffeine and the Body," Chapter 16, "Thinking Over Caffeine: Cognition, Learning, and Emotional Well-Being" and Chapter 17, "Caffeine Dependence, Intoxication, and Toxicity." The details of how caffeine permeates every cell in the body are clear, straightforward and very comprehendible. This book was written in a classical narrative style, wonderfully free of slanted opinions and unrelated ramblings in an instructional tone. This is one of the most beautifully arranged and printed hardbounds that I have found, so much that after only a few minutes I had to get my own copy! It is clear to me now that there are far more benefits to caffeine than detriments. It has been proven to increase alertness, improve concentration and even to help with weight loss, and much more. According to the book, it would take almost 100 cups of coffee to reach toxic blood levels! Even on a day where I crave two or three double lattes, I can now rest easier knowing that I'm far below toxic. But even here the authors make it clear that even after two strong cups of coffee, some of the well-known side effects can take hours to wear off: nervousness, talkativeness and anxiety. It even compares and cross-references other elements of caffeine, a member of the methylxanthine family, to other important naturally occurring compounds such as theophylline and theobromine found in cacao and yerb mate. Absolutely fascinating! The book also has me convinced that I'm hopelessly hooked to caffeine--and not just from coffee! The message: watch your intake of caffeine levels by knowing how it works in your body and where it orginated, and how other peoples of the world regard its use. No other singular work encompasses the knowledge of the world's preferred drug of choice. There is more than enough information to include as well-founded research of your own, based on the rock solid references, informative notes, beautiful black and white photographs and perfectly placed, highly detailed illustrations. The page layout is practically an art in itself, set in an older typeface reminiscent of a proprietary Garamond. Easy on the eyes, printed on natural (off-white) paper, extremely well edited and a pleasure to read! Beautiful section headers and chapter numbers resembling currency make the book visually appealing. Even the cover makes me want a cup--and a chocolate bar! Logical, no-nonsense flow from chapter to chapter. It is a real treat now to come across a book that lives beyond my expectations as an educated reader. After reading this book, you should have a degree in its own class. Top recommendation for all readers over 13. Buy it today, and don't even think about selling it!

The World of Caffeine,
By Lawrence R. Volz, M.D. (Virginia) - See all my reviews
This review is from: The World of Caffeine: The Science and Culture of the World's Most Popular Drug (Hardcover)
As a physician I found the information in The World of Caffeine both comprehensive and enlightening. I discovered many facts that I will be passing along to my patients who may not realize how much caffeine they are taking in and all the ways in which it may be affecting them. Caffeine has many potential benefits for the mind and body and a few dangers of which people should be aware. Especially sobering are the discussions of possible deleterious effects on children and a serious warning about the unknown dangers of fetal exposure. Incredibly, this is the first serious book ever written about a drug that is used almost universally. If you are going to use a drug, you should know as much about it as possible. I strongly recommend this book to everyone who uses caffeine-- in coffee, tea, colas, or pills-- and that includes almost everyone.

This review is from: The World of Caffeine: The Science and Culture of the World's Most Popular Drug (Hardcover)
This book rocks! If you drink coffee, tea or cola you need to getthis book. I'm not sure which is more fascinating-- the hundreds of surprising medical facts about caffeine's effects on the mind and body, or the astonishing part caffeine has played in culture, art, religion, society, politics, science and literature. Caffeine is the Amazing health facts include that caffeine I would say It also has dozens of illustrations and charts and
