Coffee May Help Ward Off Depression in Women, Study Finds

By Douglas Main | September 27, 2011 1:38 pm

A couple cups of coffee a day may help keep the blues away. A large epidemiological study of 50,000 women published yesterday in the Archives of Internal Medicine found that subjects who drink two or more cups of coffee on a daily basis were slightly less likely to be diagnosed with depression over a 10-year span compared to their less-caffeinated peers. Women who drank two to three cups of coffee were 15 percent less likely to be treated for the blues; those who drank four or more had a 20 percent lower risk.

A typical alcoholic energy drink is 24 ounces (0.7 liters) and has a 12 percent alcohol content—compared with a 12-ounce (0.35-liter) can of beer, which normally has 4 to 5 percent—plus the caffeine equivalent of five cups of coffee. [Scientific American]

Phusion Projects, the maker of Four Loko says it intends to remove the caffeine, as well as guarana and taurine, to bring the drink into compliance with the FDA. United Brands, which markets Joose, says the same. Despite FDA’s decision, Phusion’s leaders maintain that the alcohol-caffeine combo is not unsafe.
