NEW YORK (Reuters Health) – Drinking one cup of coffee every morning can protect against Alzheimer's, paralysis and tremor, and found that the more coffee beans are roasted, the more powerful it is, even if it is caffeine-free, according to a new scientific study. But coffee is not a clear cure for any of the diseases in any way, but researchers say it will not hurt to add a cup to your daily routine, the Daily Mail reported. Coffee roasting stimulates the release of phenylindanes, a group of compounds that block the aggregation and synthesis of proteins responsible for Alzheimer's disease and Parkinson's disease. "Coffee consumption appears to be associated with reduced risk of Alzheimer's disease and Parkinson's disease," said Dr Donald Weaver, co-author of the study at the Kremlin Institute. "They wanted to see why, and they found that caffeine-containing and caffeine-free coffee had similar capabilities in the initial experimental tests, and they concluded that the protective effect of coffee could not be because of caffeine." But the researchers found that the levels of the chemical responsible for protection from dementia and Parkinson's disease, and the degree of protection, increased as coffee was roasted.
