Cup of tea as good for you as water28th March 2011
A study has discovered that drinking four to six cups of tea every day is as good for hydration as drinking a litre of water.
The clinical trial, which took place in the UK, found that drinking that amount of tea did not have a negative impact on health.
In the study, 21 participants were divided into two groups and given either four 240ml mugs of tea to drink over a 12-hour period or one litre of water, which had been boiled and was served warm.
The tea had 20ml of milk added to it but did not contain any sugar.
The researchers also carried out another test which gave volunteers either six cups of tea or the equivalent quantity (1.5 litres) of plain water, in order to see how much difference the amount of fluid made.
The study looked at the effects of drinking either tea or water on different days and restricted the amount of exercise the participants were able to do.
The volunteers were also not allowed to drink alcohol or consume foods which contained caffeine.
The researchers took blood samples before the volunteers drank the fluid and also took samples regularly to measure hydration levels.
When they analysed the results, the researchers did not see any "significant differences between drinking tea and water".
The study was published in the British Journal of Nutrition.
Dr Carrie Ruxton, nutritional advisor to the panel, said: "Tea is an excellent way to maintain healthy fluid levels. In addition, tea is a rich source of flavonoids, which have been associated with a reduced risk of heart disease and stroke."

I am pleased to see an article which talks about the importance of hydration. However, water is the only fluid we need to hydrate and the only fluid that the British Nutrition Foundation recommends we should drink ‘plenty of’ each day. It contains zero sugar, calories, preservatives or additives; aids digestion and metabolism; replenishes natural fluids depleted by other diuretic drinks; and is a key part of the body's cooling system. As part of a healthy balanced lifestyle you can consume other drinks including milk, coffee, tea, fruit juice, smoothies and sugar sweetened beverages.
Tea contains caffeine, which can affect hydration when consumed in above average quantities. Pregnant women are advised to consume no more than 200mg or caffeine a day. This is equivalent to about two and a half mugs of tea. If these drinks are sweetened with sugar it increases the calorie content. The sugar also increases their potential to damage teeth if good dental hygiene is not practiced
