Indeed not all the bars are the same; different types of bars are used for different health benefits. Energy bars are far different from protein bars. Energy bars are rich in carbohydrates, fiber, and sugar to give instant energy. These cannot be consumed in daily routine as snacks. However, protein bars are loaded with proteins and are low in carb. But many protein bars contain some chemicals, unhealthy sweeteners, alcohols, and other unhealthy fillers, that are high in calories and shouldn’t be taken as snacks. Examine the ingredients label to make sure that your bar is made using the right and healthy ingredients.
