Readers frustrated by the lack of information on common U.S. -based foods in some earlier editions will be pleased with this updated listing. Mostly generalized foods ("graham crackers, plain") and some U.S. brand names ("Snickers bar, regular") are included with glycemic index, common serving size, available carboyhdrate (carbs-fiber) per serving, and glycemic load per serving.
A brief discussion of the nutritional reasearch used is included, but it is not the most thorough discussion of the topics (as would be expected, since this is a pocket reference guide, not the fully expanded books the author and others have published addressing specific medical and nutritional issues). The basic outline to apply this information is provided however, along with a revamped food pyramid and the recommended servings (and serving sizes) for each food group.
I did feel the additional set of charts grouping the lo, moderate, and hi GI foods for a given category (Fruit, Pizza, etc.) to be rather pointless, since the authors and other researchers have concluded that Glycemic Load (which factors in the serving size, not just the glycemic index of the carbs) is the definitive means to determine a food's affect on blood sugar and fat storage. I would have preferred the author use the space to list different versions of the serving size (28g or 1 oz or 1/3 cup) or to make the same charts based on Glycemic Load, not Gylcemic Index.
