title: Electrolytes, sugar, calories, osmolarity and pH of beverages and coconut water.
abstract: Oral rehydration has been recommended in patients with diarrhoea to replace fluid loss from the gastrointestinal tract and reduce the need for intravenous therapy. Beverages (i.e. Cola, Sprite etc.) and coconut water may be used as sources of oral fluid when glucose-electrolyte solution is not available. To evaluate the usefulness and effectiveness of these soft drinks, the basic data such as electrolytes, sugar, calories, osmolarity and pH were determined. The electrolytes of the beverages were significantly lower (p less than 0.001) than the coconut water, especially potassium. The osmolarity of the beverages, which were 693 mOsm/l, was significantly higher (p less than 0.001) than the coconut water (288 mOsm/l); pH of the beverages (3.1) was more acidic (p less than 0.001) than the coconut water (5.4). While the sugar content of the beverages, which were 8.7 gm/dl, was significantly higher (p less than 0.001) than the coconut water (1.1 gm/dl). On comparison, all brands of beverages would give more calories than the coconut water however the coconut water would be absorbed more easily than any brand of soft drink beverage.
