Craving coffee could be in your head

September 5, 2011

British researchers gave volunteers decaffeinated coffee, but told them that the drink contained caffeine. However, on a series of tests, the doctors noticed that the participants had a significant improvement in mood and performance.

In fact, some who drank decaffeinated coffee, performed better on the tests than who had caffeine.

The study is published in the journal Appetite.
