Junk food could be addictive 'like heroin'

Junk food may be addictive in the same way as heroin or cocaine, according to a study showing that laboratory rats will endure painful electric shocks to satisfy their craving for high-calorie snacks made from sausages, bacon and cheesecake.

Scientists have found that a "café-style" diet of fatty, sugary food results in compulsive overeating among rats and causes neuro-chemical changes to the brain that mimic the sort of alterations in the human brain brought about by addiction to heroin and cocaine.

The findings lend support to the idea that certain types of energy-intensive foods can trigger compulsive overeating and obesity in humans, leading to a form of food addiction that is almost impossible to overcome by dieting.
