Bad Memory? Drink More Caffeine
A team of scientists have studied folks with Alzheimer’s and found that “the group that drank the most coffee had the best memories” (source).
In a later study they plied some Alzheimer’s mice with 500mg of caffeine (where do they find these poor rodents?). With 500mg of caffeine the memories of the mice were protected (how do they test that?).
The study author recommended caffeine from coffee as the best source:
Arendash said coffee provides the best source of concentrated caffeine because it also provides antioxidants also known to provide protection against memory loss.
Caffeinated soft drinks do not deliver the same benefit because they lack those antioxidants and also contain sugars, increasing the risk for hypertension or high blood pressure.
While chocolate also is a source of caffeine, one would have to eat 5 pounds of milk chocolate to get the same effects of drinking five cups of caffeinated coffee, Arendash noted.
I wonder how a sugar-free energy drink fits into the equation?
I read a study, caffiene expands the blood vessles in the brain.
