Tea may ward off late-life dementia
Research from Finland suggests coffee and tea consumption in midlife may protect against the risk of dementia and Alzheimer's disease later on in life. The study tried to look at the long-term impact of caffeine on the central nervous system, as the pathological processes leading to Alzheimer's disease are believed to start decades before the clinical manifestation of the illness. Although the findings need to be confirmed by other studies, they point towards the possibility that dietary interventions could modify the risk of these diseases.
