There is a growing body of evidence which confirms that those polyphenols play an important role in protecting us from heart disease and cancer. Tea was first discovered more than 5,000 years ago by the legendary Chinese Emperor, Shen Nung. To find out more about the history of tea and how it is grown, visit the Tea Council's general site. Scientific researchers are investigating how tea drinking can protect us from certain diseases. Oral Health Fluoride is the most successful agent against tooth decay ever discovered.
Scientists believe that drinking tea improves oral health by helping prevent dental caries.
A British study published in 1991 suggested that heavy tea drinking could even provide some children with enough fluoride to prevent tooth decay. It has also been suggested that plaque, the scale caused by mouth bacteria that leads to gum disease, is decreased by drinking tea. These effects are probably due to tea's antioxidant components working in synergy with its fluoride content. Cancer Research suggests that tea consumption may have beneficial effects in reducing certain cancer risks. As tea is one of the most popular drinks in the world, any possible relationship between its consumption and a reduced incidence of cancer in humans is therefore of great importance.
