Detailed Nutritional Information

Hydration and 100% Orange Juice

Most people can maintain adequate hydration by drinking when thirsty and eating a healthy diet.¹⁰ However, both underhydration and overhydration (due to lack of electrolytes by overconsuming pure water) can impair performance, particularly in athletes.¹⁰ Individuals may benefit from fluids with carbohydrates and/or electrolytes during extensive periods of exercise, and beverages that appeal to taste preferences may encourage individuals to drink.¹⁰ Thus, orange juice may be a good choice to support hydration. A recent study by Maughan and others reported 100% orange juice positively affected several measures of hydration.¹ Compared to many other beverages, including water and sports drinks, participants consuming orange juice had lower urine output and a higher net fluid balance at various timepoints after consumption.  In this study, orange juice ranked among one of the highest beverages on a beverage hydration index scale together with oral rehydration solutions and milk.  Furthermore, net potassium balance was highest with orange juice and milk consumption. One hundred percent orange juice is a viable alternative for post-exercise rehydration and recovery. In a study published in the Journal of Nutrition and Health Sciences¹¹, 26 healthy young adults drank approximately 8 ounces of 100% orange juice, a sports drink or water following 80 minutes of cycling over each of 5 days. Post-exercise, 100% orange juice contributed to hydration equally as well as water and a sports drink, received positive palatability ratings, and was able to satisfy thirst while helping to achieve or maintain hydration following exercise without causing gastrointestinal distress. ^{*Values based on a 2000 calorie diet.
