To illustrate this, Dr. Clive McKay at the Naval Research Institute placed extracted human teeth in cola drinks. Within two days, the teeth became soft and the calcium from the enamel was lost. Our kidneys are often unable to excrete the excess phosphorus that causes calcium depletion. The National Academy of Sciences set 3g daily as the tolerable maximum of phosphorus that should be consumed by children aged one to eight. Potassium and sodium are generally harmless as they are naturally occurring compounds.
Sodium is responsible for regulating and transferring body fluids.
High soft drink consumption interferes with the body's metabolism, including the metabolization of iron. The Mujlisul Ulama of South Africa investigated the possibility of soft drinks containing alcohol, and looked into the case of the United States vs. Forty Barrels and Twenty Kegs of Coca-Cola trial of 1909. It was difficult for them to ascertain whether the use of ethanol in Cokes still takes place today and, if so, for what specific function. However, the extremely small amount of alcohol involved in the process becomes insignificant in the beverage. In the meantime, there are enough reasons to abstain from drinking soft drinks, including having these doubts.
