It has long been believed that coffee has certain health benefits.
Last year, it was found that drinking three cups of it was good for your heart.
And now, scientists say, it's good for your brain too, The sun Reports.
A recent study by experts at the Krembil Research Institute in Toronto, Canada, has shown that your morning cup of Joe can help protect you from Alzheimer's and Parkinson's disease.
"Coffee consumption seems to have some correlation with a reduced risk of developing Alzheimer's disease and Parkinson's disease," Dr. Donald Weaver, co-director of the Krembil Brain Institute.

"However, we wanted to investigate why this is so – which substances are involved and how they can influence the age-related cognitive decline."
Interestingly, however, is not due to the caffeine.
The scientists found that both caffeinated and decaffeinated coffees have similar beneficial properties.
The team studied three coffees: light roast, dark roast and decaffeinated dark roast.
"The caffeinated and the decaffeinated dark roast both had identical potencies in our first experimental tests," Dr. Ross Mancini, member of the research team.
"So we saw early that its protective effect was not due to caffeine."
Dr. Mancini then identified a group of compounds known as phenylindanes which are a product of the roasting process.
It has been found that they prevent the two common protein fragments found in Alzheimer's and Parkinson's from accumulating.
"It's the first time anyone has studied how Phenylindane interacts with the proteins responsible for Alzheimer's and Parkinson's," Dr. Mancini.
"The next step would be to examine how beneficial these compounds are and whether they have the ability to penetrate the bloodstream or cross the blood-brain barrier."
The best, the scientists said, was that they are naturally occurring chemicals.
"Mother Nature is a much better chemist than we are, and Mother Nature can make those connections. If you have a complicated connection, it's nicer to grow them in a crop, harvest the harvest, grind and extract the crop than try to make it, "Dr. Weaver.
However, before talking about alternative treatments, further research is needed.
Dr. Weaver concluded that the study appeared to prove that certain coffee compounds might be helpful in averting cognitive decline.
"It's interesting, but do we suggest that coffee is a cure? Absolutely not."
