Coffee Protects Against Alzheimer’s

A study from the University of South Florida and the University of Miami concluded that drinking moderate amounts of coffee daily can reduce your risk for Alzheimer’s or delay its onset. With Alzheimer’s disease, plaques and tangles accumulate in the brain killing nerve cells and their connections. This leads to progressive and irreversible memory loss. The disease starts a decade or two before memory loss becomes obvious.

The researchers recommended moderate consumption of caffeinated coffee as the best dietary option for protection against Alzheimer’s memory loss. Older adults with mild memory loss referred to as mild cognitive impairment (MCI) already suffer short term memory loss and 15% of them progress to Alzheimer’s disease. This study showed those older adults who drank 3 cups of regular coffee daily did not progress to Alzheimer’s or their conversion to Alzheimer’s was delayed by years.

Alzheimer’s-prone mice fed caffeine alone or decaffeinated coffee did not benefit from the same protective effect. It appears that caffeine interacts with a yet unidentified component of coffee that fights off the Alzheimer’s process.
