It has long been believed that coffee has some health benefits.
Last year, it was found that drinking three cups of this stuff was good for the heart.
And now, say the scientists, it's also good for your brain, The sun reports.
A new study by experts at the Krembil Research Institute in Toronto, Canada, found that your morning cup of coffee could protect you from Alzheimer's and Parkinson's.
"Coffee consumption seems to be linked to a lower risk of developing Alzheimer's disease and Parkinson's disease," said Dr. Donald Weaver, co-director of the Krembil Brain Institute.

"But we wanted to know why: what compounds are involved and how they can affect age-related cognitive decline."
Interestingly, however, it's not caffeine that deserves to be thanked.
Scientists have found that caffeinated and caffeinated coffees have similar beneficial properties.
The team studied three types of coffee: light roast, dark roast and dark decaffeinated roast.
"The caffeinated and decaffeinated black roasts both had similar potency in our first experimental tests," said Dr. Ross Mancini, a member of the research team.
"So we found early on that its protective effect could not be due to caffeine."
Mr. Mancini then identified a group of compounds called phenylindans, products of the roasting process.
They have been shown to inhibit the agglutination of the two protein fragments common to Alzheimer's and Parkinson's.
"This is the first time that we have been studying the interaction of phenylindans with the proteins that cause Alzheimer's disease and Parkinson's disease," said Dr. Mancini.
"The next step would be to determine how beneficial these compounds are and whether they have the ability to enter the bloodstream or cross the blood-brain barrier."
The scientists said the best thing to do was that they are natural chemicals.
"Mother Nature is a better chemist than us and Mother Nature is able to make these compounds. If you have a complex compound, it's best to grow it in a crop, harvest it, grind it up and extract it, rather than trying to make it, "Dr. Weaver said.
But before discussing alternative treatments, further research is needed.
Dr. Weaver concluded that the study appeared to demonstrate that some coffee compounds may be useful in combating cognitive decline.
"It's interesting, but do we suggest that coffee is a cure? Absolutely not."
