My official statement: protein bars are not superior to high protein foods like steak or eggs; they’re just incredibly convenient. For exercisers, it is much easier to snack on a protein bar than a Tupperware bowl full of chicken (on your way TO the gym, that is). They shouldn’t be relied upon for providing substantial nutrition because, well, they don’t.
That said, while perusing the various categories of protein bars at Bodybuilding.com, I found some big differences between the “best sellers,” “newest,” and “highest rated.” So which should you buy: what everyone else is buying (best sellers)? the new kids on the block (newest)? or the favorite (highest rated)?
