Obviously "barely edible" is subjective; I like many, although not all, of the flavors I've tried. Beyond that, RxBars are high in fiber -- something a lot of American diets are pretty low in -- and high in protein. Its fat is mostly unsaturated. And while it's certainly not
low sugar, it has no
added sugar -- the sugar in them comes from fruit, mostly dates.
So, no, they're probably not "health food," but they're no worse than much of their ostensible competition and arguably better than many, some of which are way closer to Snickers bars than RxBars.
