i hate protein bars and there is no such thing as a healthy protein bar
they are processed. some A LOT and some a bit
companies are clever, they will structure the bar with as little sugar and fat on the label and as much protein as possible. in the end these numbers mean JACK SHIT. there are enough loopholes where they can fool you into thinking they are 'healthy' but they aren't. they are LOADED with harmful sweeteners that may not show up as sugar in most cases.
if you insist on a protein bar check the INGREDIENTS, not the nutritional facts. look for something with minimal ingredients, that doesn't taste 'good', and ingredients that are as natural and whole as possible.
