You may be tempted to toss things in your shopping cart, like a butter blend that "helps block cholesterol," candy and soda touting antioxidants, and plenty of foods that say they're "natural." But Consumer Reports ShopSmart says not so fast. "Natural may sound good, but when it comes to snacks and cereal, there's no standard definition.

As for this butter blend, Smart Balance makes the claim it helps block cholesterol because it has added plant sterols. But how much would you need to eat to potentially lower your risk of heart disease? Jody Rohlena "You'd have to eat a minimum of 13 tablespoons every day.
