With all due respect to Leanne
hey girl!
I found her book to have pretty basic ideas...stuff that most of us understand, eat your veggies, fruits, clean proteins, complex carbs, etc....but as some have found, she uses a "tone" or something, frankly I found her to be a little stuck-up for lack of a better term. And if you are watching your sodium, then watch out for her recipes which contain lots supposedly.
But having said that, if you are kinda lost about the whole "clean eats" thing, than by all means pick it up,its worth it for that, plus its pretty cheap!
I never use cookbooks to cook "clean" when I cook, I go all out and get down and dirty with cooks like Nigella Lawson, Paula Deen and Giada!}( Have fun at Barnes and Noble, I love that store. :7
