Willett's own simple pyramid has several benefits over the traditional format. His information is up-to-date, and you won't find recommendations that come from special-interest groups. His ideas are nothing radical--if we eat more vegetables and complex carbohydrates (no, potatoes are not complex), emphasize healthy fats, and enjoy small amounts of a tremendous variety of food, we will be healthier. You'll find some surprises as well, such as doubts about the overall benefits of soy (unless you're willing to eat a pound and a half of tofu a day), and that nuts, with their "good" fat content, are a terrific snack. Relying on research rather than anecdotes, this is a solidly written nutritional guide that will show you the real story behind how food is digested, from the glycemic index for carbs to the wisdom of adding a multivitamin to your diet. Willett combines research with matter-of-fact language and a no-nonsense tone that turns academic studies into easily understandable suggestions for living. --Jill Lightner --This text refers to an out of print or unavailable edition of this title.
Willett's book is based on evidence derived almost exclusively from large cohort studies of diet and disease. He has been the architect of several such studies and is a major contributor to what we know about methods of collecting and analyzing data; he formerly served the Journal well in this capacity. His position in this regard is preeminent but not unchallenged. He encapsulates his position on the evidence in a new ``Healthy Eating Pyramid,'' a gauntlet thrown at the feet of the U.S. Department of Agriculture (USDA). He notes that the USDA Food Guide Pyramid, like Rudyard Kipling's elephant's child, got pulled into shape by competing interests, few of which cared about human health. He goes on, ``You deserve more accurate, less biased, and more helpful information than that found in the USDA Pyramid.'' Thus, the book brings us the promise of science in the service of nutrition, and as with any good scientific claims, Willett makes sure we know, up front, that all findings are provisional and all recommendations subject to change.
The central chapters of the book are derived from and explicate the layers of the new pyramid. Central to Willett's recommendations is the control of body weight, in which exercise, rather than caloric restriction, has the primary role. However, there is also helpful and practical advice on defensive eating strategies; for example, Willett states, ``Recognize that we are victims of our culture, one that glorifies excess.''
Indeed, much of what is presented in the book is sensible and practical and demystified. For example, the data and associated recommendations on fluid intake include the following: we should drink water; tap water is OK; soft drinks are full of empty calories; and fruit juice contains more beneficial substances and less sugar than soft drinks but cannot simply be substituted for water, because, of course, it does contain calories. There is also useful information on more arcane subjects: for instance, we should be careful of grapefruit juice because it modifies the absorption and metabolism of a variety of drugs in ways that may be detrimental. And there is a proper assessment of coffee drinking that I like to summarize as follows: If drinking moderate amounts of coffee is your worst nutritional vice, you are in excellent shape. Even in the area of alcohol, Willett, who has been and remains a champion of the beneficial effects of moderate consumption (which he has the courage to define), notes that if you do not drink alcohol you should not ``feel compelled'' to start. Possibly, this is a nice antidote to the widely held notion that if some is good, more is better, but his choice of words is just a little disturbing. Finally, although many self-help books with much poorer pedigrees than this one offer recipes, it is not often that they include useful rules of thumb about shopping and places to shop and even practical tips on how to make substitutions in recipes.
Are there areas where Willett's Healthy Eating Pyramid and the associated information may not be warmly embraced by others in the nutrition-and-disease research community? Certainly the switch from vilifying total fat (a position Willett abandoned early) to asserting that carbohydrate is the bad guy (a position that Willett has made his own) and that there are ``good fats'' and ``bad fats'' does not meet everybody's sniff test. The field of nutrition and chronic disease is populated by those who will agree with Willett on none, one, two, or all three of these positions. It is probably fair to say that reality is not as clear as this book suggests. It is quite clear that diets high in potatoes, olive oil, or even sugar are not harmful to all (or beneficial to all). It seems probable that in the future there will be increasingly clearer advice that is based on metabolic variations -- variations in body shape and fat distribution and subtle genetic differences in the capacity to handle major nutrients -- and that echoes what we already know about micronutrients. It may well be that the ability to handle specific foods and nutrients differs substantially from person to person and that the only universal may prove to be Willett's central tenet: match the energy ingested to the energy expended by controlling both eating and exercise.
It is an interesting paradox that doctors, scientists, and engineers are highly regarded in Western societies but that only a minority of people in those societies like reading about science or are even interested in the topic. Couple that with data from Robin Dunbar of the University of Liverpool in Britain, who found that perhaps two thirds of all human speech is gossip, and it will not be surprising if Willett's book (perhaps like those by Stephen Hawking) sells well but has no impact at all on human behavior or even understanding.
