According to a recent study that drinking tea has been established as a healthy habit, with its benefits extending to nasopharyngeal carcinoma (NPC) prevention.

The study was conducted in Southern China, where it involved 2,441 histopathologically confirmed NPC patients, through a population-based case-control study, and 2,546 controls. Experts calculated the average daily ethanol (grams per day) and tea intake (mL/day) and evaluated its efficacy on the risk of NPC.

Utilizing the multivariable logistic regression analysis revealed that compared with non-consumption, alcohol intake overall exerted no negative influence on NPC risk in men, nor did heavy drinking or former alcohol drinking.

In the meantime, current tea drinking has contributed to NPC risk reduction relative to non-consumption. Participants in the low firs three quintiles of average daily current tea intake were at significantly lower NPC risk, however not significant for the next two quintiles.

According to the restricted cubic spine analysis, regular tea drinking had a significant nonlinear dose-response correlated with NPC risk.

Further studies may be required to fully establish the biological mechanisms that may correlate tea drinking with nasopharyngeal carcinoma (NPC) risk. For complete details of the study, click here.
