Compounds that can be found in green tea have been shown to reduce the inflammation associated with periodontal disease, according to a new study.
Scientists from Kyushu University in Fukuoka, Japan, investigated the impact of green tea consumption on male participants aged 49-59 with varying levels of periodontal disease.
They observed that for every one cup of green tea consumed per day, there was a decrease in three symptoms of the condition, including periodontal pocket depth, clinical attachment loss of gum tissue and bleeding on probing of the gum tissue.
The most likely explanation for the beneficial effects of green tea is the presence of the antioxidant catechin.
Antioxidants have the ability to reduce inflammation in the body, and by interfering with the body’s inflammatory response to periodontal bacteria, green tea may help promote periodontal health, and prevent further disease.
"Periodontists believe that maintaining healthy gums is absolutely critical to maintaining a healthy body," says Dr. David Cochran, chair of the Department of Periodontics at the University of Texas Health Science Center.
"That is why it is so important to find simple ways to boost periodontal health, such as regularly drinking green tea – something already known to possess certain health-related benefits."
The study was published in the Journal of Periodontology and adds to a growing body of evidence regarding the benefits of drinking green tea, especially in weight loss and control, heart health and cancer prevention.
