Show I Damage Reported By Soft Drinks Rats have toothache at the Naval Nav-al Medical Research Institute, Bethesda, Md. Popular soft drinks fed to the rats in large quantities ruined the enamel on their teeth. Three Navy doctors blamed the damage on phosphoric acid combined com-bined with sugar in the drink, and pointed out that humans may not suffer to that extent because of differences in the saliva and in the amounts of the drink consumed, but revealed an experiment in which extracted human teeth were imersed in a cola beverage. After two days they lost much of their surface-hardening calcium. |
