Are protein bars healthier than candy bars?

Some are, but many carry a similar amount of sugar once you add up the coating, caramel, and sweeteners — the protein is a real benefit, but it doesn't cancel out a high sugar count.

How do I find a genuinely low-sugar protein bar?

Check the nutrition label for sugar per bar rather than trusting the protein number on the front — the better options are usually under 5 g of sugar and built around nuts or whey rather than a chocolate-and-caramel structure.

How Much Sugar Is in a Protein Bar?

A typical protein bar has about 15 g of added sugar — the protein claim on the front often distracts from a sugar count close to a candy bar's.

Fine in a portion — worth keeping an eye on.

A standard protein bar carries about 15 g of added sugar — in the same range as a chocolate chip cookie or a small milk chocolate bar. The high protein number on the front of the wrapper is real, but many bars use chocolate coatings, caramel layers, and sugar alcohols alongside genuine sugar to make the bar palatable, and the sugar count gets far less attention than the protein grams.

Not every bar is like this — some genuinely low-sugar options exist, usually built around nuts and a minimal binder rather than a candy-bar structure. The only reliable way to tell them apart is the label: flip it over and check sugar per bar, not just the protein headline on the front.
