As a recent grad, my diet went to hell. Actually, my diet was never that great to begin with. But Jamba Juice, in its numerous locations everywhere, are a great way to get more fruits (sometimes veggies, too) in my diet. Not all drinks taste great, though. I stick with "Tropical Tango," which is no longer on the menu but tastes the best. For every person, there's a flavor for you, so don't worry.
A huge precaution: Jamba Juice is very high in calories. A "power size" (the largest) can run upwards to 600 calories! This is not meant to be a meal supplement because, wow, you'll be gaining weight like crazy. Take it in moderation.
