Not all studies have shown that sports drinks are the optimal drink for rehydration. A study in 1994 by Hickey, Costell and Trappe, took a less scientific approach to determining what beverage is best to consume. In 1968, studies showed that 2.5% was the highest concentration of sugar that you could put in your exercise drink and still absorb it rapidly. This posed a problem because drinks taste best when they contain a 10% concentration of sugar. Coca Cola and all soft drinks fruit juices contain 10% sugar. Soon after these studies, manufacturers started to sell exercise drinks containing 2.5%. They didn't taste good because the concentration of sugar was too low, so some manufacturers added saccharin to sweeten the taste. Twenty years later, studies refuted those done in 1968 showing that only drinks that contained less than 2.5% sugar were absorbed rapidly. The 1968 studies were done on resting people. When the same studies were repeated on exercising people, 10% sugared drinks were absorbed rapidly. Other studies in the 1960's showed that carbonation and warmness delayed emptying into the blood. Several studies since then show that carbonated drinks are absorbed as rapidly as non- carbonated ones and that warm drinks are absorbed as rapidly as cold ones. When you exercise, drink any fluid that you prefer. The data clearly shows that the drink that will rehydrate you best is the one you prefer to drink at any temperature, salt concentration or carbonation (Hickey, Costell & Trappe, 1994). These results have also been supported by other studies. A palatable flavour is known to enh
