American scientists from Stanford University have found an explanation why coffee drinkers generally live longer.
According to researchers, the secret lies in caffeine, which helps to reduce the level of chronic inflammation in the body. It lies at the heart of most age-related diseases, including cancer, Alzheimer’s, heart disease and blood vessels, osteoarthritis.
Experiments on mice have helped to establish that the metabolites (breakdown products) of nucleic acids circulating in the blood from increased activity of free radicals that can cause inflammation in the body.
In turn, caffeine and its metabolites (e.g., theophylline contained in tea, and theobromine, which is a lot chocolate) successfully opposed inflammatory action of metabolites of nucleic acids.
Previously, scientists found that caffeine reduces the risk of cirrhosis due to alcohol.
