Three cups of coffee a day are said to protect against Alzheimer's
The number of people with dementia continues to rise. In Germany alone, around 1.5 million people suffer from dementia, most of whom have Alzheimer's. Scientists have now found that the risk of developing this can be reduced by consuming coffee.
Coffee is healthier than expected
Coffee has long been considered a health hazard, but today we know that the popular hot drink is healthier than most people think. It can be good for the heart and also prevent hardening of the arteries. According to scientific studies, coffee can also reduce the risk of colorectal cancer. And now scientists have found that consuming coffee can also reduce the risk of dementia.
Three to five cups of coffee a day
According to a report by the international “Institute for Scientific Information on Coffee” (ISIC), moderate coffee consumption has an impact on stopping cognitive decline.
Coffee is full of antioxidants that are said to reduce the risk of developing type 2 diabetes or developing a liver disease. But they should also protect against Alzheimer's.
According to the current study, the risk of developing dementia is reduced by up to 27 percent by consuming three to five cups of coffee a day.
Braking cognitive decline
"Health experts play an important role in providing their patients with accurate information based on the latest research - so that they can follow a healthy diet and lifestyle and thus slow down age-related, cognitive wear and tear," explained Professor Rodrigo Cunha of der University of Coimbra in Portugal.
"A moderate coffee enjoyment could play an important role here, which in turn would be reflected in the expenditure of the health systems in Europe," said the expert.
A cup of coffee usually contains about 75 to 100 milligrams of caffeine. The European Food Safety Authority (EFSA) recommends healthy people not to consume more than 400 milligrams of caffeine a day.
Where caffeine works in the brain
Earlier studies have shown that caffeine in coffee can work against Alzheimer's. For example, scientists recently reported on a study that coffee consumption can lower the risk of dementia in women.
Researchers at the German Research Center Jülich found out years ago "that caffeine works in precisely the brain regions that are also affected by Alzheimer's disease", as Prof. Dr. Andreas Bauer from the Institute of Neuroscience and Medicine explained at the time. (ad)
