Rebecca, I have a book on the Paleo diet and it restricts amounts of fruit by grams of fructose. However, I have read a few different books on Paleo diet and some are by authors who have their own spin or interpretation of the diet. These other authors do not limit fruits in the same way or based on the same rationale. So there is, as far as I can see, no "consensus" on the issue. Some fruits have more sugar than others and some would look at that but remember that the Paleo Diet is not a diet that was designed for IBD.
The book I have is a Paleo Diet applied to autoimmune disorders/IBD and it outlines a protocol. The protocol and restrictions are discussed by the author here:
