Health risks of phosphoric acid in cola drinks


A Reza Kamarei

Cola is a sweetened carbonated soft drink flavored with cola flavor. The cola flavor is the signature flavor among carbonated soft drinks and is enormously popular worldwide. Cola flavor (including an acidic flavoring agent such as phosphoric acid) and sweeteners are the required ingredients for the production of colas. Other ingredients, such as color, caffeine and preservatives, are added (as needed) as complementary or auxiliary ingredients. Phosphoric acid (also known as orthophosphoric acid) is a solid, non-toxic inorganic acid. The most common form of phosphoric acid is colorless, odorless 85% syrupy aqueous solution. Food-grade 85% phosphoric acid has a pH level below 1, meaning it should be distributed by licensed professionals and manufacturing staff who interact with this chemical should wear proper safety attire and equipment. The American Beverage Association defines phosphoric acid as follows: “This flavoring agent in soft drinks is a preservative that provides tartness.” Numerous health risks due to the use of phosphoric acid in colas have been reported in the scientific literature. Careful review of the scientific literature shows that there are three major health risks associated with phosphoric acid in colas: risk to bone health, risk to kidney health and risk to teeth health. Consumers deserve to be informed about the presence of phosphoric acid in their cola drinks. It is reasonable to demand use of appropriate cautionary language about phosphoric acid on the labels of cola drinks.
