(Newser) – Researchers don’t quite know why, but a new study suggests that moderate coffee intake dramatically reduces the likelihood of Alzheimer’s disease, AFP reports. A 20-year Finnish study of 1,409 subjects shows middle-aged people who drink 3-5 cups a day are 60% to 65% less likely to contract the disease later in life.

Explanations for coffee’s Alzheimer-fighting properties are wide-ranging. A cup of joe contains strong antioxidants, known to reduce risk of the disease. Also, coffee has been shown to protect against diabetes, a predictor of Alzheimer’s, and to aid the nerve system, helping ward off dementia. The revelation comes a day after another study demonstrated a link between excessive caffeine intake and hallucination.

There are perhaps one or two other studies that have shown that coffee can improve some memory functions, but this is the first study directed at dementia and Alzheimer's in which the subjects are followed for such a long time. - Miia Kivipelto, University of Kuopio
