Oreos can be as addictive to the brain as cocaine, the authors of a scientific study have claimed. The chocolate cookies have been found to trigger the same neurons in the brain’s ‘pleasure centre’ as the outlawed drug during extensive lab testing on rats.
Neuroscientist Joseph Schroeder from Connecticut College in New London, Connecticut, led research into the addictive effect of the indulgent treat.
His team discovered that the hungry rodents’ reaction to the biscuit was comparable to that of rats who had been offered cocaine in earlier tests.
As well as finding that, like humans, rats prefer to eat the cream part of their Oreo first, scientists also saw similarities between the levels of addiction in ‘Oreo rats’ and their cocaine hooked cousins.
To arrive at the conclusion, Schroeder placed rats in a maze which had two routes to different treats.
One on side, they placed rice cakes and on the other they placed Oreos.
After the animals had explored the maze fully, they were then left to choose which treat they would prefer to stay at.
