Eating junk food has been found to be as addictive as smoking or taking heroin.
Addiction to Junk food can cause compulsive eating and obesity, according to a study.
For the first time this American study has discovered that the human brain may react in the same way to junk food as it does to drugs.
American researchers found that a diet of chips, burgers and sausages programmes the human brain to crave more sugar, salt and high fat food.
Researchers at Scripps Research Institute, Florida, found that lab rats became addicted to an unhealthy diet, as addicted as humans become to cocaine and heroin.
The findings do not directly transfer to human obesity.
However, overconsumption of high calorie foods does trigger addiction-type of responses in the brain.
