They're the latest pop-ular snack-craze - chips that are popped. And they're being pitched by pop stars like Katy Perry... The popped snacks are made of corn, rice, potato, chickpeas, or a mix of those. And then, rather than fried, most are heated and pressurized -- until they pop.

The clear message is that these popped snacks are more healthful. But we wondered if they really are," says testers from Consumer Reports. After "crunching" nutritional data for 12 different popped chips, Consumer Reports found, it's a "mixed bag." Most are less than 130 calories and four grams of fat per serving. But that's actually more than some healthier crunchy-snacks like Lay's Baked! Original Potato chips, which have about the same number of calories - but half the fat.  
It's also more than Quaker Salt Free Rice Cakes, which have no fat and only 35 calories each.
