If you drink 3-5 cups of coffee a day, new research spells good news for you! A moderate intake of coffee may provide protection against age-related cognitive decline and other neurodegenerative diseases such as Alzheimer's and Parkinson's disease, says recent research.The researchers, from the University of Coimbra (CNC) in Portugal, suggested that regular, long-term coffee drinking may reduce the risk of Alzheimer's disease by up to 27 per cent.The greatest protection against cognitive decline can be seen at an intake of nearly 3-5 cups of coffee per day, they said."Moderate coffee consumption could play a significant role in reducing cognitive decline which would impact health outcomes and healthcare spending," said Professor Rodrigo A. Cunha, at the university.Caffeine, anti-inflammatory agents as well as antioxidants such as caffeic acid -- a polyphenol (antioxidant) found in coffee -- may be associated with the improved cognitive function, the researchers said.Intake of up to 400mg of caffeine -- the equivalent of up to 5 cups of coffee per day -- from all sources do not raise any concerns for healthy adults, suggested European Food Safety Authority (EFSA) in its scientific opinion on the safety of caffeine. The research was presented at ISIC's symposium held during the European Union Geriatric Medicine Society's 2016 Congress in Lisbon recently.
