June 30, 2011- We have all been told for years that coffee is unhealthy and addictive. A new study shows that coffee may be good for us and may help keep Alzheimer’s at bay.
A study was recently published in the Journal of Alzheimer’s Disease. Mice brains were tweaked to have a human gene with Alzheimer’s and like humans the mice started to be increasingly more forgetful as they aged.
What was really amazing was with the equivalent of four to five cups of coffee a day, the mice started to get improved memories according to Gary Arendash, one of the authors of the study and a scientist in Tampa at the Florida Alzheimer’s Disease and Research Center.
Earlier research has showed that caffeine at least could partially block beta amyloid production the protein that is sticky and clogs Alzheimer’s patient’s brains. Healthy and Alzheimer’s mice were treated with caffeine or decaffeinated coffee and then tests were done to see if either of the beverages increased memory.
The test they used is very similar to one used to diagnose those with Alzheimer’s. Some may dismiss the study due to it only involving rodents. Arendash says he also has new data that is from humans. The data is being analyzed he said but thus far it looks as though the same affect that caffeine has on mice it has on humans.
