The Daily Telegraph reported that drinking more than three cups of tea a day cuts the risk of a heart attack. The newspaper said that according to research, tea – with or without milk – may also strengthen bones.
It adds that the “beneficial effects on many biochemical effects in the body” are due to polyphenols, which are natural plant antioxidants in tea.
A review conducted in 2001 of 10 follow-up studies, found that the risk of heart attack was reduced by 11% when three cups of tea per day were drunk (237ml).
Other studies that have since been conducted showed similar results, with four studies demonstrating links between tea consumption and reduced risk of CHD death and risk factors.
Five studies investigating bone health suggested that tea had a ‘modest beneficial effect’ on bone mineral density, with most benefit seen in elderly women who drank four or more cups per day.
The clearest consistent evidence points to an association between tea consumption, in excess of three cups per day, and a reduced risk of myocardial infarction. There is no consistent evidence to indicate that tea drinking has detrimental effects on hydration, bone health, or iron status.
The methods used to conduct the search for reviews or individual tea studies are not clear from the report. For now, it may be best for people to continue to enjoy a cup of tea because they like it, rather than hoping for protection from heart attacks.
