Too much coffee can increase the risk of Mild Cognitive Impairment (MCI), a new study suggests

Many studies suggest that coffee provides a lot of health benefits to the body. Regular coffee consumption reduces the risk of diabetes, heart diseases, and depression. Those studies had such an impact that people were thinking about taking more coffee.

A new study shows that drinking one or two cup coffee a day improves cognitive abilities. That moderate amount of coffee lowers the risk of mild cognitive impairment (MCI). MCI is a prodromal phase of Alzheimer’s and dementia. Reconfirming what was said in many previous studies.

But the interesting part of the study is that higher consumption of coffee increased the risk of MCI. Those who started to take more coffee (from one cup to more) had two times higher rate of MCI compared to those who started to take less than one cup of coffee a day. And have one and a half times higher risk of MCI than who continues to drink one cup a day.

The research was conducted on 1,445 individuals from 65 to 84 years of age. The results suggest that “cognitively normal older individuals who never or rarely consumed coffee and those who increased their coffee consumption habits had a higher risk of developing MCI.

Therefore, moderate and regular coffee consumption may have nueroprotective effects also against MCI confirming previous studies on the long-term protective effects of coffee, tea or caffeine consumption and plasma levels of caffeine against cognitive decline and dementia.” Vincenzo Solfrizzi and Francesco Panza, investigators from University of Bari Aldo Moro, Italy and the authors of study titled "Italian Longitudinal Study on Aging" wrote.

The change in coffee consumption habits is not a healthy sign. The moderate and steady doze of the substance can improve memory performance. But the excessive intake can result in impaired memory functioning.
