A review of the all of the available evidence shows that regularly drinking coffee, around two to thre cups a day, cut the risk by as much as a quarter.

Although the protective effects of coffee have been suggested before previous studies have proved conflicting.

More than 120,000 people in Britain suffer from the debilitating neurological condition.

There is currently no cure for the disease, and scientists do not yet understand what causes it.

The latest research looked at 26 published studies into the link.

Collating the results, the researchers found a 25 per cent cut in the chance of developing the disease among coffee drinkers.

However, that fell to 14 per cent when the researchers looked only at female coffee drinkers.

There was also a direct link between the amount of coffee drunk and the extent of the protective effect conferred, the researchers found.

The theory is that caffeine is reducing the amount of neuro-transmitters produced by the brain, transmitters that may actual do damage to surrounding brain tissue. The actual action of caffeine in the brain is not known. It may also interfere with uptake of other transmitters, allowing the levels of dopamine to increase.

The polyphenols in green tea may also have a preventative effect with regards to Parkinson’s disease. These chemicals act within the brain to improve the flow of dopamine between portions of the brain. Parkinson’s is caused by a lack of dopamine in one part of the brain, and these polyphenols could prevent that depletion.

Studies with Parkinson’s and polyphenols have been conducted in labs with mice, but there have been no actual tea-drinking studies done with humans.
