Example: Sunbelt Blueberry Harvest Chewy Granola Bars

With 2.5 grams of saturated fats (thats the bad kind, folks), these little bars would contribute 13 percent of your daily recommended value of saturated fat, while raising your total and LDL cholesterol levels (again, the bad ones). The American Heart Association cautions that high LDL cholesterol levels can lead to a build-up of plaque in your arteries. So the less you eat, the better.
