Maybe I choose a bad example. Cordain also says that coffee and alcohol are okay to drink, though Paleo people didn't drink alcohol. Yet he doesn't allow vinegar--says to use lemon or lime juice instead. Don't you get vinegar by letting wine ferment a little longer? What's the difference? The difference is some studies that show vinegar can have a negative health impact--studies that have nothing to do with what Paleo people ate or didn't eat. And I highly doubt Paleo people drank coffee. That's why I say this book is more about Cordain's opinions about nutrition than Paleo nutrition per se. Cordain may well have interesting and worthwhile views on general nutrition, but that's not what I was hoping to get when I preordered this book. ================= Rick Strong wrote: Sheryl, recall that "paleo people" did not eat factory raised, grain-fed, agri-business chicken. There is a huge distinction between the fat profile of such a bird and those feeding in their natural range, no? Sheryl said: I found Cordain's book to be disappointing, too. I wanted to read the most recent findings and evidence of what paleo people ate, and THEN an analysis of the implications. Instead, I read a bunch of diet recommendations that seemed to be only tangentially related to paleo eating. For example, he says to only eat the white meat of a chicken. I'm sure paleo people didn't throw out part of every bird they killed. This seems to be a book on nutrition with conclusions drawn from many sources--only one of which is what paleo people ate. He doesn't hesitate to recommend deviations from paleo eating if it meets his own criteria for good nutrition. This isn't the type of book I was hoping for.
