Middle-aged people who can afford a moderate amount of coffee a day can protect themselves from Alzheimer's disease, at least to some extent, hopefully share scientists from the Scandinavian countries. According to them, moderate means between 3 and 5 cups of coffee a day, where the risk decreased by 60 - to 65%. These findings, published in the latest issue of the Journal of Alzheimer's Disease, are the result of the work of doctors from the Karolinska Institutet, Finland, in more than 1,400 people in a study lasting more than 20 years.
The information in the study included knowledge about the participants' habits - whether and how often they drank coffee - once reported at an average age of 50, and a second time when they were 65 to 79 years old. Among them, 61% developed dementia by this age, and 48% of them had Alzheimer's disease.
It is not known exactly how coffee prevents dementia, the role of antioxidants in it is assumed. Others have argued that caffeine has a protective effect on nerve tissue. Observations have highlighted the importance of coffee in the prevention of diabetes, and the latter is again associated with Alzheimer's.
There are tests that link caffeine to hallucinations, but it's probably far beyond normal consumption. Obviously, here, as everywhere, moderation gives the optimal effect.
