Tea... is there no end to its talents?
Numerous studies have already shown the multiple health benefits of drinking tea. The list goes on...
Green tea has been shown to inhibit growth of Helicobacter pylori, which is a carcinogen and the most important risk factor for gastric cancer. Researchers also evaluated the effects of green tea on the development of Helicobacter-induced gastritis in an animal model and demonstrated that green tea consumption can prevent gastric mucosal inflammation if ingested prior to exposure to Helicobacter infection. (Green tea inhibits Helicobacter growth in vivo and in vitro. Int J Antimicrob Agents. 2009 May;33(5):473-8).
A meta-analysis of data from nine studies involving 194,965 individuals suggests that daily consumption of three cups per day of either green or black tea could prevent the onset of ischaemic stroke. (Green and black tea consumption and risk of stroke: a meta-analysis. Stroke. 2009 May;40(5):1786-92).
However, authors of a Cochrane Database systematic review of fifty-one studies involving more than 1.6 million participants have concluded that there was insufficient evidence to give any firm recommendations regarding green tea consumption for cancer prevention. (Green tea (Camellia sinensis) for the prevention of cancer. Cochrane Database Syst Rev. 2009 Jul 8;(3):CD005004).
