Don't be fooled by the name—those vegetable versions of cheese puffs are made with very little produce and have up to twice the sodium of potato chips for only about 30 fewer calories. Air-popped popcorn gives you the same crunchy goodness and loads more. Three cups counts as a serving of whole grains and packs more antioxidants than a serving of fruit or vegetables, a recent University of Scranton study reported. "That’s because the antioxidants are more concentrated in popcorn due to its lower water content compared to fluid-rich produce," Sass explains. And while three cups of plain air-popped popcorn has only 93 calories compared to veggie snacks' 140, who really wants a flavorless snack? Add some oil and herbs, and both your body and your taste buds will enjoy the 160 to 220 calories.
