Nature Valley, Chewy Granola Bars: Are they healthy?

I have always been tempted to try these bars as the pictures are great and they say 100% All Natural Snack. They must be good!!!

Each bar contains 120 Calories, which is fine, but what is the percentage of fat? The box shows that 3.2 grams of fat are there in one bar which works out to 28.8 calories. So the percentage of fat from calories is 28.8/120 = 24%. Far too high. Too maintain a lean body, your fat level from any food source should not exceed 10% of calories. In addition, this bar has 7.2 grams of sugar. Net results is high fat and high sugar in the Nature Valley bar. I guess most bars must follow the same logic.
