Expat health insurance customers might wish to increase their consumption of black tea, as it is thought to be beneficial to a person's wellbeing.
Tea Advisory Panel (Tap) member Dr Carrie Ruxton said it "may be useful for oral health", as flavonoids in the brew have "potent anti-bacterial properties".
It is thought that anti-cancer properties also exist in the product, although "conflicting results" have been discovered in large-scale human trials, she continued.
Dr Ruxton therefore did not give recommendations regarding a link between tumour prevention and tea consumption.
However, the fluoride contained in the drink is known to protect tooth enamel, she continued.
It is a natural source of this substance as tea leaves accumulate it from the soil, with the calcium contained in the milk many people add to the drink further contributing to healthy teeth and bones.
Recent research, commissioned by Tap and to be published in Network Health Dieticians has found black tea provides the same benefits to a person's wellbeing as green tea, which generally gets more attention in regards to health benefits.
