Drinking coffee has been linked to lowering the risk of mild cognitive impairment (MCI), which is a slow and increasing decline in cognitive abilities, such as memory and thinking skills. But, according to a new study published in the Journal of Alzheimer’s Disease, participants who increased their coffee consumption during the 3½-year study period were twice as likely to develop MCI than those who limited their coffee intake to one cup or less per day. Those who maintained a consistent coffee intake (neither increasing or decreasing intake) showed no increased risk of MCI.
The take-away? Moderate and regular coffee consumption (a cup of coffee a day) may have neuroprotective effects against MCI, but the greatest risk comes for those who rarely drink coffee and increase intake over time.
