TORONTO (WTHR) — A research study suggests coffee can protect you against developing Alzheimer's and Parkinson's.

According to the study conducted by Krembil Brain Institute in Toronto the compound known as phenylindanes, which is found in coffee, is believed to be beneficial to brain health. The study tested Starbucks VIA coffee in light roast, dark roast and decaffeinated dark roast.

"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. "But we wanted to investigate why that is -- which compounds are involved and how they may impact age-related cognitive decline."

Research found that dark roast has the highest quantity of phenylindanes making it the most effective for the brain.

Phenylindanes prevent two protein fragments common in Alzheimer's and Parkinson's diseases, according to a study published in Frontiers in Neuroscience last month.

Although the study proves that coffee has some sort of benefit to personal health, Dr. Weaver says more testing needs to be conducted.

"What this study does is take the epidemiological evidence and try to refine it and to demonstrate that there are indeed components within coffee that are beneficial to warding off cognitive decline. It's interesting but are we suggesting that coffee is a cure? Absolutely not."
