This is indeed very good news for coffee drinkers, especially those with a family history of Parkinson's disease, according to the science site EurekAlert.
According to lead author, Professor Tan Eng King, PhD, senior consultant, Department of Neurology, National Neuroscience Institute of Singapore, caffeine has the potential to combat Parkinson's disease and other neurodegenerative diseases.

He explains that the reason caffeine does this is because it reduces inflammation in nerve cells in the brain.
What did the study find?
The study included 4,488 participants who were asked to answer questions about their daily caffeine consumption.
Of the participants, 1,790 had Parkinson's disease, 2,698 did not, and all had one of two Asian gene variants associated with the disease.
Drinking 2 cups of coffee a day can help reduce the risk of Parkinson's disease by 4-8 times
The results found that drinking four to five cups of Western-style Arabica coffee or two cups of Robusta coffee a day could reduce the risk of Parkinson's disease by four to eight times, according to EurekAlert.
The researchers also found that the more caffeine consumed, the greater the effect, but even drinking less than 200 mg of caffeine per day still reduced the risk of disease. And the maximum is 400 mg of caffeine per day (about 3 - 4 cups).
Professor Tan said the research has important implications for preventing Parkinson's disease, especially in countries where the Asian gene variant is common.
Both coffee and tea are rich sources of caffeine, and moderate caffeine consumption is a simple way to reduce your risk of Parkinson's disease.
