Dark Roast Coffee Helps Prevent Alzheimer's

Identified as an effective drink for the prevention of Alzheimer’s disease

Identified as an effective drink for the prevention of Alzheimer’s disease

Coffee is one of the most widely consumed beverages worldwide, with approximately 500 billion cups consumed annually. As a result, they have established for substances that trigger the development of neurodegenerative diseases that affect coffee is a strong roast and strong roast without the caffeine.

For the study, reported in the journal Frontiers in Neuroscience, the team chose to investigate three different types of coffee - light roast, dark roast and decaffeinated dark roast. "The caffeinated and de-caffeinated dark roast both had identical potencies in our initial experimental tests", said Ross Mancini, a research fellow from Krembil Research Institute. However, as demonstrated in this study, the protective effect has not caffeine, and a substance contained in coffee.

The study has identified the set of compounds in coffee - phenylindanes, produced during the roasting process - that are responsible for protecting the brain.

Energy Information Administration said U.S. oil production will be higher this year and in 2019 than previously forecasted. Yet big things are happening on the other side of the supply equation too, meaning the risk of scarcity may not last.

Phenylindanes is the key compound in coffee that had an anti-clumping effect on protein fragments beta amyloid and tau.

"So phenylindanes are a dual-inhibitor. Very interesting, we were not expecting that", Dr. [Donald] Weaver [co-director of the Krembil Brain Institute] acknowledges. The compounds were found in higher numbers the longer the coffee has been roasted, so this is excellent news for those who like a dark roast. Now researchers have to figure out how easily these antioxidants from a well-roasted coffee beans is able to enter the bloodstream and cross the blood-brain barrier to enter the brain and deactivate it threaten the human protein accumulation. "If you have a complicated compound, it's nicer to grow it in a crop, harvest the crop, grind the crop out and extract it than try to make it".
