Question: are luna protein bars good for you?
Answer: As far as a carb-protein-fat ration in a Luna Bar, most bars in the line rake up around 25 grams of carbs, 8 grams of protein, and 6 grams of fat (1/3 of which are healthy monounsaturated fats). So they're probably not for people who are trying to bench 300 pounds, but I think this is a pretty decent showing!
