These bars are a good balance of healthy fats (from the nuts), carbs (from the dates), and protein (from the egg whites in the original bar, nuts, and hemp hearts in this recipe). These RX protein bars are going to give you a more steady energy boost, unlike candy or simple carbohydrate snack bars. The fat and protein will stop you from having a blood sugar crash, which often creates that tired and moody feeling. RX bars are sweetened with dates. Dates contain fiber which supports your blood sugar levels, they also are high in antioxidants.
