Green tea

„According to a survey released by the United States Department of Agriculture in 2007, the mean content of flavonoids in a cup of green tea is higher than that in the same volume of other food and drink items that are traditionally considered of health contributing nature, including fresh fruits, vegetable juices or wine. “

„Flavonoids are a group of phytochemicals present in most plant products that are responsible for health effects such as anti-oxidative and anticarcinogenic functions. However, based on the same USDA survey, the content of flavonoids may vary dramatically amongst different tea products.“
