People beyond young adulthood but before the onset of old age, middle aged people that are enjoying their favorite coffee between 3 and 5 times a day, lowered their risk of developing dementia and Alzheimer's disease by between 60 and 65 percent later in life.
This fact is confirmed by a study by Finnish and Swedish researchers showed Thursday. The study is based on repeated interviews with 1,409 people in Finland over more than two decades.
A total of 61 people had by then developed dementia, 48 of whom had Alzheimer's, the researchers said.
"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 (and) in which the subjects are followed for such a long time,".
It remained unclear exactly how moderate coffee drinking helped delay or avoid the onset of dementia, but pointed out that coffee contains strong antioxidants, which are known to counter Alzheimer's. Researchers should try to nail down exactly what the protective elements in coffee consist in.
The Finnish-Swedish research results surfaced just a day after a separate study published by psychologists at Durham University showed a link between heavy coffee drinking and hallucinations.
"I guess this shows that you shouldn't exaggerate," Kivipelto said when asked about the British study, pointing out that her research showed "insignificant" benefits to drinking more than five cups of coffee a day when it came to protecting against dementia.
