According to a new research the researchers have found the phenylindanes in coffee It may block two pieces of protein. These protein fragments contribute to the development of alzheimer's and Parkinson's diseases, so coffee may help prevent these diseases.

This study was conducted by Donald Weaver, PhD, co-director of the Krembil brain institute and with the help of Biologist Yanfei Wang and Chemist Ross Mancini, PhD, tested three different types of coffee, including dark, lightly roasted and caffeine-free black coffee.After further study, they discovered a group of compounds called phenyllindene in coffee beans.Amyloid beta and tau are common in both diseases, Dr. Weaver said, and phenyllindan ACTS as a dual inhibitor that inhibits two protein fragments found in alzheimer's and Parkinson's diseases.

In the three test coffee samples, the deep-roasted coffee contained more phenyllindene because the beans experienced more roasting, which promoted the production of the compound.

This is the first time that phenyllindene has been studied in relation to alzheimer's and Parkinson's disease, and given that phenyllindene is used in coffee as an antioxidant in foods and beverages, it may have other health benefits as well.More research on phenylindene will be crucial "to determine whether phenyllindene has a protective effect on alzheimer's disease, cardiovascular disease, cancer and other diseases."

At this moment, deep roasting coffee should not be seen as a preventive against alzheimer's or Parkinson's disease. Further research is needed to determine whether phenyllindene is absorbed into the bloodstream, gets into the central nervous system, and affects gut microbes.
