Impact:
Junk food can give you an "addicted brain"!?
In the experiment, a group of rats were allowed unlimited access to junk food. And after a while, they were given a painful electric shock if they eat junk food. The rats contiunes to eat even though they would be shocked. This behaviour is similar to rats addicted to cocaine. It is likely that junk food is as addictive as drug, and it may as well applicable to human.
