(Caracas, November 10 – Europa Press) .- Coffee consumption at breakfast not only provides an increase in energy and attention but can also protect against the development of both Alzheimer's disease and Parkinson's disease, according to a new study by the Brain Institute of Krembil, Toronto (Canada).
"Coffee consumption seems to have some association with a lower risk of developing Alzheimer's and Parkinson's," explains Dr. Donald Weaver, co-director of the Brain Brain Institute. But we wanted to investigate why it's happening, which associations are involved, and how they can affect the cognitive decline associated with age. "
Dr. Weaver relied on Dr. Dr. Weaver's help. Ross Mancini, a researcher of medical chemistry, and biologist Yanfei Wang. Explore three different types of coffee: light roast, dark roast and dark roasted with no caffeine.
"Both caffeine, decaffeinated and caffeine-free, had identical potential in our initial experimental tests, so we noticed from the outset that their protective effect was not due to caffeine," he explains.
Dr. Mancini then identified a group of compounds known as phenylindans, which result from the process of roasting coffee beans. Fenildans are unique because they are compounds studied in the study blocking the clustering of both amyloid beta and tau, two protein fragments common to Alzheimer's and Parkinson's patients. "So, the pindindans are double inhibitors, it's very interesting and we did not expect it," says Doctor Weaver.
Since browning creates higher amounts of phenylindan, dark baking appears to be more protective than light baking. "This is the first time anyone investigates how phenylalanine interacts with the proteins responsible for Alzheimer's and Parkinson's," says Dr. Mancini. The next step would be to investigate to what extent these compounds are beneficial and whether they have the ability to reach the bloodstream or cross the blood-brain barrier. "
The fact that it is a natural union over a synthetic is also a big advantage, recognizes Dr Weaver. However, He admits that even more research is needed to translate into possible treatment options. "What this study does is to get the epidemiological data and show that there are actually coffee ingredients that are beneficial to prevent cognitive decline." "It is interesting, but we suggest that coffee is a cure, absolutely not," he warns .
