Drinking coffee can reduce the risk of Alzheimer's and Parkinson's disease: study

"Coffee consumption seems to be linked to a lower risk of developing Alzheimer's disease and Parkinson's disease," said Donald Weaver of the Krembil Research Institute in Canada.

Scientists say your morning cup of coffee may protect you from developing Alzheimer's disease and Parkinson's disease. Scientists suggest that there may be more to this morning jolt of kindness than a boost in energy and attention. "Coffee consumption seems to be linked to a lower risk of developing Alzheimer's disease and Parkinson's disease," said Donald Weaver of the Krembil Research Institute in Canada.

"But we wanted to know why it's what compounds are involved and how they can affect age-related cognitive decline," Weaver said. The team chose to look at three types of coffee: roasted coffee, roasted coffee and roasted decaffeinated coffee. "The caffeinated and decaffeinated black roasts both had similar potency in our initial experimental tests," said Ross Mancini, a research scientist at the Krembil Research Institute.

"So we found early on that its protective effect could not be due to caffeine," said Mancini. 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 amyloid beta and tau, two common protein fragments in Alzheimer's and Parkinson's diseases. ,. "Phenylindans are therefore a double inhibitor.

Very interesting, we did not expect that, "Weaver said. 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 that we have been studying the interaction of phenylindans with the proteins that cause Alzheimer's disease and Parkinson's disease," said 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," he said.
