Drinking three or more cups of tea a day is as good for you as drinking plenty of water and may even have extra health benefits, say researchers.
The work in the European Journal of Clinical Nutrition dispels the common belief that tea dehydrates.
Tea not only rehydrates as well as water does, but it can also protect against heart disease and some cancers, UK nutritionists found.
Experts believe flavonoids are the key ingredient in tea that promote health.
Healthy cuppa
These polyphenol antioxidants are found in many foods and plants, including tea leaves, and have been shown to help prevent cell damage.
Tea replaces fluids and contains antioxidants so its got two things going for it
Lead author Dr Ruxton
Public health nutritionist Dr Carrie Ruxton, and colleagues at Kings College London, looked at published studies on the health effects of tea consumption.
They found clear evidence that drinking three to four cups of tea a day can cut the chances of having a heart attack.
Some studies suggested tea consumption protected against cancer, although this effect was less clear-cut.
Other health benefits seen included protection against tooth plaque and potentially tooth decay, plus bone strengthening.
Dr Ruxton said: "Drinking tea is actually better for you than drinking water. Water is essentially replacing fluid. Tea replaces fluids and contains antioxidants so it's got two things going for it."
Rehydrating
She said it was an urban myth that tea is dehydrating.
"Studies on caffeine have found very high doses dehydrate and everyone assumes that caffeine-containing beverages dehydrate. But even if you had a really, really strong cup of tea or coffee, which is quite hard to make, you would still have a net gain of fluid.
"Also, a cup of tea contains fluoride, which is good for the teeth," she added.
There was no evidence that tea consumption was harmful to health. However, research suggests that tea can impair the body's ability to absorb iron from food, meaning people at risk of anaemia should avoid drinking tea around mealtimes.
Tea is not dehydrating. It is a healthy drink
Claire Williamson of the British Nutrition Foundation
Dr Ruxton's team found average tea consumption was just under three cups per day.
She said the increasing popularity of soft drinks meant many people were not drinking as much tea as before.
"Tea drinking is most common in older people, the 40 plus age range. In older people, tea sometimes made up about 70% of fluid intake so it is a really important contributor," she said.
Claire Williamson of the British Nutrition Foundation said: "Studies in the laboratory have shown potential health benefits.
"The evidence in humans is not as strong and more studies need to be done. But there are definite potential health benefits from the polyphenols in terms of reducing the risk of diseases such as heart disease and cancers.
"In terms of fluid intake, we recommend 1.5-2 litres per day and that can include tea. Tea is not dehydrating. It is a healthy drink."
The Tea Council provided funding for the work. Dr Ruxton stressed that the work was independent.

Well i don't know really how much tea you can drink in a day without letting it damage your health. I tried looking it up because at the moment I'm drinking tea. I found a bit of information that might help. There is caffeine in tea and you shouldn't consume a lot of caffeine in a day. That can be bad for you. One bad side effect of caffeine is sleep disruption. Other side effects include withdrawal headaches caused by dilation of blood vessels in the head, lethargy, irritability, and constipation. The amount of caffeine varies greatly depending on the type of tea and the brewing time. For information on how many cups you can drink? Well I'd contact your doctor on that. I don't know for sure.

Tea won't damage your health at all. It is recommended that you drink at least 3-4 cups a day as research has recently prooved that tea gives you better coping mechanisms and allows your stress levels to return to normal twice as quickly, after a stressful time. So don't worry about drinking it. just don't drink it too late or it may keep you awake. If you're worried about caffeine, you can now buy decaffeinated tea.

Doctors don't recommend any more than 3 cups a day because of the caffine, tar, fat from milk, sugar if you have it. Try to ween yourself off ordinary tea and try some herbal and fruit teas, much better for you.

Depends on the tea. If you're drinking a common tea leaf with milk, sugar, etc...I would limit it to 2 cups.
With green and natural herbal teas, 3 cups....
Using low-fat milk also helps....

I recently read that research has shown that tea is good for you and has anti cancer properties, even up to 8 cups a day is beneficial

Tea is good and bad for you in different ways. It has anti-oxidants, so, in theory, the more the better. It also has caffeine, which won't kill you, but it can mess with your sleep, and that is really bad for you. Other than that, it might stain your teeth.

If you are not staying in cold country you should have zero consumption of tea. Tea causes inefficiency of intestines and affects appetite.
