For some reason, when I am pregnant, I crave jamba juice. There's just something about their thick, cold, fruity drinks that is both delicious and satisfying. However, beware of falling into the trap of thinking a Jamba Juice is the healthiest option out there. If you check out their nutrition book, found in each store, you'll notice that the regular size drinks pack around 500-600 calories each, so guzzling one of these down in addition to a meal might not be the best choice. There is also a lot of sugar in most of the drinks. On the flip side, they do blend supplements into each drink and the fruit naturally contains a lot of natural goodness. Plus, if you are pregnant, who's going to stop you from "feeding baby?"
