Coffee consumption helps prevent Alzheimer's disease: Study

DBR Staff Writer Published 22 June 2011

University of South Florida researchers have found that consumption of coffee prevents the occurance of Alzheimer's disease.

According to the study, caffeine boosts the blood levels of a critical growth of granulocyte colony stimulating factor (GCSF) protein, which is usually decreased in patients suffering with Alzheimer's disease, reports medindia.net.

The researchers conducted a treatment on Alzheimer's mice and normal mice, which showed caffeinated coffee increased blood levels of GCSF.

Although the study was performed in Alzheimer's mice, the researchers gathered clinical evidence of caffeine/coffee's ability to protect humans against Alzheimer's, which they are planning to publish soon.

The study states that average American drinks 1 to 2 cups of coffee a day, considerably less than the amount the researchers believe required to protect against Alzheimer's disease.

The researchers believe that moderate daily coffee intake starting at least by middle age (30s - 50s) is required for reducing the risk of getting Alzheimer's disease, while starting it even in older age appears protective from the disease.

University of South Florida neuroscientist and lead author of the study Chuanhai Cao said," Caffeinated coffee provides a natural increase in blood GCSF levels and the exact way that this occurs is not understood."

"There is a synergistic interaction between caffeine and some mystery component of coffee that provides this beneficial increase in blood GCSF levels," Cao added.
