Far too much sugar and processed flours. I don't find cereals in general to be a good breakfast (imo, for me) but, if you do want cereal, follow the guidelines in the book. A good one to try would be Uncle Sam or Kashi (not Go Lean Crunch).
Fiber One and All Bran are pretty good-not alot of sugar and high fiber. You really have to read the ingredient and nutritional labels. It's amazing how much sugar is added to just about all breakfast cereals.
