Love your coffee? It turned out that there could be more to the morning jolt of kindness than a boost of energy and attention. Drinking coffee can protect you from the development of both Alzheimer's and Parkinson's disease.
According to a new study, around 500 billion cups of coffee are consumed each year worldwide. The results of the study are published in the Journal of Frontiers in Neuroscience
"Coffee consumption seems to correlate with a decrease in the risk of developing Alzheimer's disease and Parkinson's disease, "said Dr. Donald Weaver, researcher. But we wanted to know why – what compounds are involved and how they can affect cognitive decline related to age. "
The team of researchers chose to examine three types of coffee: roasted coffee, roasted coffee and roasted decaffeinated coffee.
"The caffeinated and decaffeinated black roasts both had similar potency in our first experimental tests," said Dr. Ross Mancini, researcher. "So we found early on that its protective effect could not be due to caffeine."
Dr. Mancini then identified a group of compounds called phenylindans, which result from the roasting process of coffee beans. Phenylindans are unique in that they are the only compound studied in the study that prevents – or rather inhibits – both beta-amyloid and tau, two common protein fragments in the diseases of humans. Alzheimer's and Parkinson's ,. "Phenylindans are therefore a double inhibitor, and interestingly, we did not expect that," said Dr. Weaver.
Since roasting leads to higher amounts of phenylindans, dark roast coffee appears to be more protective than light roast coffee.
"This is the first time anyone has studied how phenylindans interact with the proteins responsible for 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.
