To meet energy demands, some studies indicate that as much as 33% of the daily energy intake of children may come from snacking occasions which are often composed of just simple sugars and void of nutrients. The fat-free raisin is a nutrition energy source similar in energy density to popular energy bars on a calories-per-gram basis. In addition, the energy raisins provide is well utilized by the active body.
Active adults also benefit from eating raisins. A recent study showed that adults who ate raisins prior to and during intense workouts experienced lower or no DNA damage compared to the control group. According to Gene Spiller, Ph.D., who conducted the study, “this data leads one to believe that foods with a high ORAC value, such as California raisins, when used as a source of energy during strenuous exercise, protect most athletes from oxidative damage.” Oxidative damage is linked to a person's ability to fight chronic diseases, such as heart disease or certain types of cancer. Strenuous exercise can induce free radical formation in muscle and increase the need for antioxidants. The study found that athletes who ate approximately one cup of raisins before and during a triathlon were better protected from oxidative damage as measured in the urine than those who consumed a glucose drink of equivalent caloric value.
