Experts have been advising since years to drink eight glasses of water a day to keep fit, but researchers now have been suggesting that it does not contribute a bit to health, according to a recent report published in the Australian and New Zealand Journal of Public Health.

The team of researchers at the Pennsylvania University has been saying after a review that instead of drinking eight glasses of water, one should for two litres of liquids of different flavours.

It is being said that eating nutritious food along with having fruits can provide almost 90-95% of water. Also, juices can be taken in and even an apple is equivalent to drinking a glass of water.

The team says that lots of water is not beneficial for the body, but rather can cause health hazards. It has been told that excessive consumption of water can cause the brain to swell. While it has no link with helping in dieting or preventing headaches or enhancing the skin tone, it certainly is associated with enrichment of bottling companies.

"Your body is very good at thirst. Listen to your body's thirst mechanism. If you're thirsty, have something to drink", says public health researcher Rob Quigley.
