i love Kashi too but i do not think that it has the fiber of Fiber One. 14 grams per half a cup to Kashi's 2.5 grams per half cup. But, I think that Kashi has more protein, too.
I really enjoy the Cinnamon Harvest by Kashi. The local Cub stores in my area have most of the Kashi cereals on sale 3 for $7.98!! Great price for great cereal that not only tastes good, but fills me up!
you might try Kashi go lean crunch - it's delicious, but I can't eat it because it has too much fiber for me... I eat the kashi cinnamon one and love it!
