The sta­tus of Green tea as Super­food grows as a study finds it even abol­ishes bad breath. It’s already known that Green tea helps pre­vent can­cer and heart disease.

Green tea can help to beat bad breath, accord­ing to sci­en­tic research.  The study found that antiox­i­dants in the tea, called polyphe­nols, destroy a num­ber of com­pounds in the mouth that can lead to bad breath, tooth decay and even mouth ulcer.

The study from Israel’s Insti­tute of Tech­nol­ogy will add to green tea’s sta­tus as one of nature’s so-called “superfoods”.

Green is already said to help pre­vent can­cer and heart dis­ease and lower cho­les­terol – and even ward off Parkinson’s and Alzheimer’s.

Writ­ing in the Archives of Oral Biol­ogy, the sci­en­tists called for more stud­ies, adding: ‘All together, there is increas­ing inter­est in the health ben­e­fits of green tea in the field of oral health.’

Green tea is made from the same plant as black tea but processed in a dif­fer­ent way that means it retains less caf­feine and more polyphenols.


It has been drunk in China and the Far East for thou­sands of years and is fast becom­ing pop­u­lar in Britain par­tic­u­larly because of its health benefits.

It is also more likely to be drunk with­out milk or sugar so it tends to con­tain fewer calo­ries too.

The study, pub­lished in the jour­nal Archives of Oral Biol­ogy, exam­ined the prop­er­ties of the polyphe­nol called epi­gal­lo­cat­e­chin 3 gal­late (EGCG) in par­tic­u­lar and reported:

Tea polyphe­nols pos­sess antivi­ral prop­er­ties, believed to help in pro­tec­tion from influenza. Addi­tion­ally green tea polyphe­nols can abol­ish hal­i­to­sis through mod­i­fi­ca­tion of odor­ant sul­phur com­po­nents. Oral cav­ity, oxida­tive stress and inflam­ma­tion con­se­quent to cig­a­rettes’ dele­te­ri­ous com­pounds may be reduced in the pres­ence of green tea polyphenols.
