These popular bars certainly can be good for you. They can also be little better than a candy bar. It depends on the ingredients.
Food manufacturers often create products they call "protein bars," but which don't offer much protein, and contain plenty of ingredients you may not want. Choose bars that provide an ample amount of high-quality protein without high amounts of calories, carbohydrates, and fats to help you lose weight, build lean tissue, and control hunger. If the bar has a very poor protein-to-carb ratio, meaning there are far more carbs than protein, you may be paying premium prices for what is basically junk food.
Pick from this list of the best bars to make sure you're not just eating candy bars in disguise. You can also make your own! By using the right ingredients, you can rest assured that the bars you eat are good for you.
