This is frightening:

The study found that people who only tasted beer, without any effect from the alcohol itself, had dopamine, a brain neurotransmitter associated with alcohol and other abused drugs, released into the brain.

It suggests that flavors -- such as beer! -- set off chemicals in some peoples' brains that we associate with addiction.

Some foods are addictive for some people, and it's FLAVOR that actually set them off.
