Five Cups of Coffee a Day May Help Alzheimer’s

Five Cups of Coffee a Day May Help Alzheimer’s

Researchers are saying 500mg of caffeine a day might protect the brain from Alzheimer’s disease. That’s like five cups of regular coffee per day!

Gary Arendash, a researcher at Florida Alzheimer’s Disease Research Center, have been studying how caffeine affects the brains of mice with Alzheimer’s diasese. Their research found that, by adding caffeine in the mice’s diet, the rodents were able to perform better on short-term memory and thinking tests. They also found that these caffeinated mice have 50% less in abnormal amyloid proteins (the brain protein believed to be the cause of Alzheimer’s.)

“The human equivalent of two to three cups of coffee does not have benefits in our Alzheimer’s mice.”

Although this finding is very interesting – but drinking 500mg of caffeine a day can be considered as caffeine overdose.  The symptoms of caffeine intoxications may include restlessness, excitement, insomnia, gastrointestinal disturbance, and irregular or rapid heart beat.

The best way to prevent Alzheimer’s (and even just being healthy), is through regular exercise, healthy diet, good sleeping hours to rest your brain, and doing brain exercises (puzzles). [NPR]
