Researchers from the University of South Florida have given you yet another justification for your caffeine addiction. 

The study involved 124 people ages 65 to 88 in Tampa and Miami, Florida and suggests that older adults with mild cognitive impairment (MCI) who drink about three cups of coffee per day can significantly reduce the risk of developing Alzheimer’s disease. 

In fact, 100 percent of the study participants with MCI who had a blood caffeine level above 1200 ng/ml – the equivalent of drinking several cups of coffee within a few hours of their blood draw – did not develop Alzheimer’s disease within two to four years.
