Rats became'hooked'on sausage and cheesecake in same way as drugabusers.
Junk foodmay beaddictivein the same way asheroinorcocaine, according to a study showing that laboratory rats willendurepainful electric shocks tosatisfytheircravingfor high-calorie snacks made from sausages,baconand cheesecake.
Scientists have found that a "café-style" diet offatty, sugary food results incompulsiveovereating among rats and causes neuro-chemical changes to the brain that mimic the sort ofalterationsin the human brain brought about by addiction to heroin and cocaine.
Thefindingslend support to the idea that certain types of energy-intensive foods cantriggercompulsiveovereating and obesity in humans, leading to a form of food addiction that is almost impossible to overcome by dieting.
The researchers found that rats offered junk food quickly became so attached to it that they would endure painful but harmless electric shocks to their feet in order to eat it. They would even prefer tostarvethemselves rather than eat the "salad bar option" of the typicalrodentfood eaten by rats that had never had junk food.
"They always went for the worst types of food and, as a result, they took in twice the calories as the control rats. When weremovedthe junk food and tried to put them on anutritiousdiet - what we call the 'salad bar option' - they simply refused to eat," Professor Kenny said. "The change in their diet was so great that they basically starved themselves for two weeks after they were cut off from their junk food."
Professor Kenny added: "These findings confirm what we and many others have suspected, that overconsumption of highly pleasurable food triggersaddiction-like neuroadaptive responses in brain reward circuitries, driving the development of compulsive eating."
