A healthier option than ice cream or a milkshake, juices and smoothies are great refreshers, especially when the heat index is in the triple digits. Keva features about 25 combinations, some with sherbet or frozen yogurt, others without. Some favorites include the tangy Cranberry Kicker with cranberry juice, banana, raspberry sherbet, blueberries and raspberries; and the Ragin' Bull, with Red Bull energy drink, guava juice, orange sherbet, strawberries and peaches. To boost nutrition, add a "Gizer" (short for Energizer), such as extra protein or a stress relief vitamin complex. Keva Tempters are a bit more indulgent, but still healthier than a traditional milkshake – splurge on the peanut butter chocolate version, or the Oreo Speedwagon.
