Report spruiks the brain health benefits of coffee
Another study has reinforced the possible health benefits of coffee, this one claiming that it may reduce the risk of age-related cognitive decline, including Alzheimer’s and Parkinson’s disease.
New research from the Krembil Brain Institute in Canada shows that coffee could protect the brain against developing Alzheimer’s and Parkinson’s disease.
“Coffee consumption does seem to have some correlation to a decreased risk of developing Alzheimer’s disease and Parkinson’s disease,” Dr Donald Weaver, co-director of the Krembil Brain Institute said in a statement.
“But we wanted to investigate why that is – which compounds are involved and how they may impact age-related cognitive decline.”
Researchers studied the effects of different blends and roasts and found that darker roast better protected against cognitive decline.
Even decaffeinated dark roasts had positive effects, so it's not just caffeine that promotes positive long-term health outcomes.
Compounds known as phenylindanes found in coffee are known to prevent two proteins common in Alzheimer’s and Parkinson’s from clumping.
Darker roasts have higher quantities of phenylindanes and lower levels of caffeine.
“It’s the first time anybody’s investigated how phenylindanes interact with the proteins that are responsible for Alzheimer’s and Parkinson’s,” said Dr Mancini.
“It’s interesting, but are we suggesting that coffee is a cure? Absolutely not.
“The next step would be to investigate how beneficial these compounds are, and whether they have the ability to enter the bloodstream, or cross the blood-brain barrier.”
