Most of the Pure Protein bars are pretty good (from Worldwide Sport Nutrition). The Next protein bard (Detour, Joyride, One Way) are really good too, but they arer higher carb and there has been some disputes about the actual protein and sugar content which has been found to be respectively lower and higher than the label claims. But it may have been rectified by now. Some of the low carb bars are ok, but it's really dependent on taste. Bars in general are not what I would consider 'healthy' however. Usually high sodium, artificial sweeteners, preservatives and such. I'm a huge fan of Greens Plus bars, but they are stupid expensive. I only use them in emergency situations like vacation when I cant exactly carry my own food around with me.
