The potential long-term benefits of coffee keep piling up, too, with research showing that drinking it regularly may help prevent liver disease, type 2 diabetes, at least nine types of cancer, and even neurodegenerative diseases like Parkinson’s and Alzheimer’s. In new research exploring how it may counteract those brain diseases, researchers tested several components of coffee, including a group of compounds known as phenylindanes, which are created when coffee beans are roasted. In a lab, phenylindanes prevented two types of protein fragments that are common to both Parkinson’s and Alzheimer’s from clumping together. When these proteins clump together in people’s brains, they create the plaques and tangles that are hallmarks of Alzheimer’s and Parkinson’s. More research is needed, but it may be that the phenylindanes in coffee are good for your brain. Dark-roast coffee was higher in phenylindanes than light roast, and for those who avoid caffeine, there’s good news: decaf has the same levels of phenylindanes as regular! That said, the data on protection from Alzheimer’s and Parkinson’s is at least twice as great from caffeinated as decaffeinated.
