Coffee can reduce your chances of Alzheimer's and Parkinson's disease


If you drink coffee regularly, you can get more than a quick caffeine hit.

According to a new study, it could help protect you from the development of Alzheimer's and Parkinson's disease.

Coffee consumption seems to have some links with a reduced risk of Alzheimer's and Parkinson's disease, said dr. Donald Weaver, co-author of the Canadian Brain Institute, Krembi Brain, who performed the study.

"But we wanted to explore why this is – which compounds are involved and how they can affect age-related cognitive decline."

The research team examined three different types of coffee: a light roast, a dark roast and a caffeinated dark roast.

A group of compounds known as "phenylindanes" that are formed as a result of the coffee bean roasting process were identified.

Phenylindanes can prevent or inhibit the accumulation of two protein fragments (beta amyloid and tau), which are common in Alzheimer's and Parkinson's disease.

"The first one has investigated how phenylindanes work with proteins that are responsible for Alzheimer's and Parkinson's disease," said Dr. Ross Mancini, a research assistant in medical chemistry who took part in the work.

"The next step would be to explore how useful these compounds are and whether they have the ability to enter the bloodstream or cross the blood-brain barrier."

However, it acknowledges that there are many more studies needed before the benefits can be transferred to therapeutic options.

"What this study does is to take epidemiological evidence and try to improve it, and to prove that there are actually components in the cavity that are useful for preventing cognitive decline," he said.

"It's interesting, but we suggest coffee is a cure? Absolutely not."
