Sweetened Acidic Beverages' Short-Term Impact on Human Saliva Properties

Posted: September 9, 2025
A recent study explored the impact of consuming sweetened acidic beverages, specifically apple juice, on the tribological properties, viscoelasticity, and protein composition of human saliva. The research, conducted on 32 healthy adults, found that both water and apple juice caused increased friction in saliva compared to unstimulated whole mouth saliva. However, the delubricating effect of water was greater than that of apple juice, with friction coefficients returning to normal after 10 minutes. Analysis of protein composition showed different effects of water and apple juice on salivary proteins. This study sheds light on the transient nature of delubrication caused by sweetened acidic beverages and calls for further research on their impact on oral health.
