Query: Disappointed

I suppose if you are new to the whole superfoods theory this might be an okay start. However, I've read too many other good authors' works to have gone through this book and not say anything. The information is dated, at times misleading and inaccurate. I have three of this authors' Superfoods books. I should have bought only one prior to the other two. If you want to truly educate yourself, start with "The 150 Healthiest Foods on Earth" by Jonny Bowden, then try "seasonal food" by Susannah Blake, "The Food Substitutions Bible" by David Joachim and "the new whole foods encyclopedia" by Rebecca Wood.
