Research suggests that *coffee consumption may have a protective effect against dementia and cognitive decline*. A notable study from the CAIDE project found that drinking 3-5 cups of coffee daily at midlife was linked to about a 65% reduced risk of developing dementia or Alzheimer’s disease later in life. The benefits are thought to come from caffeine’s stimulating effects on the brain, as well as other compounds in coffee that have antioxidant and anti-inflammatory properties. Coffee may improve cognitive performance by reducing oxidative stress and inflammation, which are key factors in neurodegeneration. Additionally, regular coffee intake has been associated with slower accumulation of amyloid plaques, a hallmark of Alzheimer’s disease. Moderate coffee consumption appears to be a promising lifestyle factor for maintaining brain health and delaying dementia onset.
