coffee: do you love coffee? It turns out you can protect it against the development of Alzheimer's and Parkinson's



WASHINGTON DC. [USA]: Do you love your coffee? It turns out that there could be more shaking in the morning than a boost of energy and attention. Drinking coffee can protect you against the development of Alzheimer's and Parkinson's disease.

According to a new study, about 500 billion coffee cups are consumed around the world every year. The results of the study are published in the Journal of Frontiers in Neuroscience

"Coffee consumption seems to have some correlation with the risk of developing Alzheimer's disease and Parkinson's disease," said Dr. Donald Weaver. "But we wanted to investigate why it is what they are involved and how they can affect the cognitive decline related to age."

The team of researchers chose to investigate three different types of coffee – light baked roast, dark roasted and decaffeinated toasted roast.

"Roasted roasted with caffeine and decaffeinated both had identical powers in our initial experimental experiments," Ross said. Dr. Mancini, a researcher. "Then we observed from the beginning that its protective effect could not be due to caffeine."

Dr. Mancini identified then a group of compounds known as phenylindanes, that arise as a result of the roasting process for coffee beans. Phenylindanes are unique because they are the only compound investigated in the study that prevents, or rather, inhibition, both beta-amyloid and tau, two fragments of common proteins in Alzheimer's and Parkinson's, from clumping. "Then the phenylindanes are a dual inhibitor. Very interesting, we were not expecting that," said Dr. Weaver.

As roasting leads to higher amounts of phenylindanes, dark roasted coffee seems to be more protective than roasted coffee.

"It's the first time someone investigates how phenylindanes interact with proteins that are responsible for Alzheimer's and Parkinson's," said Dr. Mancini. "The next step would be to investigate how these compounds are beneficial and if they have the ability to enter the bloodstream or cross the blood-brain barrier."
