2.0 out of 5 stars
Some info is absolutely wrong, August 22, 2007
This review is from: The New Optimum Nutrition Bible (Paperback)
My concern about this book is that I found some very specific but blatant errors of information re: one topic the author discusses, and this makes me wonder what other errors he made. The rest of the book might be entirely accurate, but unfortunately when there are such basic conceptual errors (not typos, actual wrong info that is thoroughly discussed and analyzed incorrectly) it calls into question the rest of the info.
In one section, the author discusses information related to exercise physiology and the expenditure of energy during activity. There are several fundamental errors in his information, and this makes me question whether some or much of the other info in this book (other than the exercise physiology info) is also erroneous.
I will share two specific examples of errors in this author's information. First, he states that the fitter you are the more calories you will burn to complete a given task. This is actually the opposite of what is true. Sure, a fitter person likely has a faster resting metabolic rate which means s/he'll burn more calories throughout the day, but to perform a specific task for a specific period of time (as stated in the author's example) the fitter you are the more efficiently your body will perform that task, and the less energy you'll expend to complete it. His basic premise is absolutely wrong, and thus the nutritional advice that he provides stemming out of that info is flawed.
The second specific example of a blatant error is when the author states that running a mile burns 300 calories. While I suppose this is potentially true for a few individuals, most exercise physiology experts agree that most people will burn approximately 100 calories to run a mile. Of course the exact number will vary depending on the individual's level of fitness, body weight, body composition, the speed at which they run, the terrain (flat, hilly, etc) but most people will burn about 100 calories to run a flat mile, give or take maybe 25 calories. The author's claim of 300 calories is SO far from what is standardly agreed upon as a reasonable ballpark estimate of caloric expenditure it is useless. Unfortunately, the author also then goes on to make nutritional recommendations that stem from this error.
My biggest concern is that if the author made these types of basic errors that demonstrate a fundamental misunderstanding of human physiology (which I caught only because of my exercise physiology knowledge) how reliable are the author's nutritional recommendations? What other errors has he made that I might not catch if I don't have expertise on some other topic in this book (such as the biochemistry of a specific nutrient). A thorough and accurate understanding of physiology is an essential part of the foundation upon which sound nutritional recommendations should be based. I am not convinced that this author has that necessary foundation and for me that makes this book of questionable value.

A great easy to read book on nutrition, March 6, 2006
This review is from: The New Optimum Nutrition Bible (Paperback)
This is an excellent book that is easy to read and understand. The cost and size make it especially appealing for a non-medical person who wants the basic info about diet and nutrition.
