I have Carpender's '500 l/c Recipes'; (the first edition) and the Eadeses' 'Comfort Foods' cookbook, and while both are interesting reading, neither one fits into my favorite cookbooks category in the same way that Mollie Katzen's/Moosewood's stuff, or Paul Prudhomme's stuff or Jeff Smith's stuff always has. Those are cookbooks to which I return over and over because the recipes are inventive and they inspire me. The books you're asking about--not so much.
I have to agree that as a cookbook junkie (I've probably got 300+), I think a cookbook that specializes in a diet with specific nutrient requirements/restrictions should provide COMPLETE nutrient information. Yes, local ingredients will vary--but there's no reason to not include that info for each recipe, except that it's an extra step in testing. When the nutrient info is there, any level of cook can figure out how to make the recipe work for his/her family. Without it, they're just shooting in the dark. My recipes always include nutrient info, and I work really hard to ensure that they're accurate--after all, recipe software only costs about 10 bucks!
One l/c cookbook that does present usable family-friendly recipes with readily available ingredients, pictures, good directions and full nutrient information is Rodale's "Lose Weight the Smart Low Carb way," written by Bettina Newman and David Joachim. I like this book so much that I reviewed it for 'CarbHealth' magazine, and I've bought it twice--at retail--as gifts for friends who were just starting to low carb and couldn't figure out what to eat.
Rodale's plan is higher carb than most, but you don't have to use their plan to enjoy the recipes, which make up two-thirds of the book. About two-thirds of the recipes are right at home on Atkins (after induction) or Protein Power, and all of them would work on the Zone, South Beach or Schwarzbein. There are even some good (different) vegetarian choices, so it's a really effective resource. Enjoy!
