Black jumbo raisins are our extra large, deliciously sweet and nutritious dried raisins. Used for muesli and cakes, or simply just for snacking, they add a natural sweetness that is unparalleled by other raisins. Raisins are rich in carbs, especially natural sugars, they give you a quick boost of energy when you’re feeling sluggish -- without weighing you down. For this reason, raisins make an excellent pre- or post-workout snack. Raisins contain about 130 calories and 31 grams of carbs in each 1/4 cup portion. A 2011 study published in the “Journal of Strength and Conditioning Research” reports that raisins are a feasible energy-boosting alternative to sports jelly beans during high-intensity endurance exercise.
