In light of the fact that the number of elderly citizens in society is steadily increasing, the search for dietary factors which might prolong mental agility is growing in significance. Coffee, together with its main ingredient, caffeine, has been the focus of much attention from various researchers, as data on its beneficial effects on human health continue to accumulate. Most reports indicate that moderate coffee consumption may in fact lower the risk for common neurodegenerative conditions, i.e. Alzheimer's and Parkinson's diseases. Regardless, due to their complex pathogenesis as well as methodology of scientific research, the exact impact of coffee consumption remains to be fully elucidated. At present, it seems safe to inform the general public that coffee drinkers need not fear for their health. Possibly, in the future experts will recommend drinking coffee not only to satisfy individual taste preferences but also to decrease age-related mental deterioration.
