Need a quick pick-me-up? Try munching on these:
Cheese Quesadilla: Get a calcium, fiber, and vegetable fix in less than a minute. Fold a slice of low-fat Monterey Jack into a whole-wheat tortilla, heat for 45 seconds in the microwave, and top with salsa.
Vegetable Juices: The blends contain lycopene, antioxidants, fiber, and other vitamins, minerals, and nutrients that protect you against everything from cancer to high blood pressure. Even better, they often contain vegetables you might not otherwise get—like beets and watercress.
Instant Oatmeal: Didn't eat enough at lunch? Fill up on oatmeal for a fiber-rich mid-afternoon nosh. (Make it with skim milk instead of water for a calcium boost.) Studies have shown that eating oatmeal regularly can help cut your cholesterol.
Energy Bars: When you really need to "grab it and go," reach for an energy bar that's low in calories and fat and contains a healthy dose of vitamins C and E, iron, and calcium. "They're a lot better for you than eating a candy bar!" Franzese says.
