A new study published in the Journal of Nutrition and Health Sciences found drinking 100% orange juice after exercise, contributes to hydration equally as well as water and sports drinks.
Assistant Professor at the University of Kansas and principal investigator, Dr. Dawn Emerson: “There were no symptoms of serious GI [gastrointestinal] distress with the orange juice despite the carbohydrate content and acidity of the beverage. The results indicate that people can drink orange juice to aid in their rehydration and recovery after exercise.”
Researchers at the University of Kansas conducted the study with funding provided by the Florida Department of Citrus. The study found no differences between 100% orange juice, sports drinks or water with respect to taste preference, thirst level, hydration or gastrointestinal distress after exercise.
Researchers conducted a five-day exercise study with 26 healthy young adults who were moderately trained for endurance exercise. Each day, they cycled on a stationary bike for 80 minutes and then consumed about 8 oz. of 100% orange juice, orange-flavored water or orange-flavored sports drink.
