raisins are an excellent source of natural sugars. They can be a
good source of energy during endurance type exercise. Twelve 12-
to 14-year old boys and girls played two regular soccer games on
two different days. During the break the players were randomized
to take either two servings (3 oz, or 84 g) of sun-dried raisins
with a glass of water, or just water. During the second game the
players switched treatments, so that each subject was tested with
and without sun-dried raisins. The players’ blood sugar was
measured at the beginning and within one minute after the end of
The comparison of blood sugar levels between the two treatments
showed that consumption of sun-dried raisins resulted in significantly
higher blood sugar levels at the end of the game compared to when
only water was consumed. Therefore, the sun-dried raisin snack maintained
higher blood sugar levels to support the constant demand for fast
energy required during the soccer match.
Sun-dried raisins are an effective, practical way to maintain blood
sugar levels and support the demand of energy during sports activities
in young players.
