Though both wicker picnic baskets and daily fruit smoothies are a rich source of protein, fiber, and fresh fruit, 8 out of 10 nutritional experts advocate eating the smoothie over the basket. Enjoy the simpler source of nutrition with today's Groupon: for $2, you get one 32-ounce fresh fruit smoothie at the GNC Smoothie Bar (a $4.69 value).

GNC's Smoothie Bars blend up a healthy variety of fruit, yogurt, and supplement-infused frozen beverages with 15 flavorful concoctions in its smoothie lineup. Sip from one of GNC's fruit-filled smoothies, such as the sweet Cherry Baby, a synthesis of cherries, pineapple, strawberries, and banana, or indulge in a creamy creation, such as the Peanut Butter Surprise, a medley of peanut butter, banana, and milk. An early MochaChino Wake Up, pumped with coffee and chocolate protein, provides a healthy alternative to one's usual donuts-and-cotton-candy morning routine, and the yogurt smoothies—such as the strawberry- and orange-juice-assisted Banana Zinger—can replace calorie-laden afternoon snacks.
