I believe that you should limit your carbs to the absolute minimum. There is lots of reference for this. See mercola.com. Read Metabolic Typing Diet. This book by Wolcott should be of benefit to you. Basically it says that what one diet for one person thats works may not be suitable for the next person. So each person should strive to seek their own diet and start to take responsiblity for their own health. Remember, Sugar is Sugar whether it is natural or not.
Good Luck.
