Straight From the Headlines: Eating Junk Food An Addiction?
According to a recent study published in the journal “Nature Neuroscience,” a high-calorie diet, including junk food, may be as addictive as drugs like nicotine or even cocaine.
The study, conducted on rats, shows that over consumption of high-calorie foods can trigger addiction-like responses in the brain, thereby turning the rats into compulsive eaters.
Decreased levels of a specific dopamine receptor : a brain chemical that allows a feeling of reward : have been found in these overweight rats, as they are found in humans with drug addictions.
The research was conducted in conjunction with the announcement that obesity-related diseases cost the U.S. and estimated $150 billion each year and an estimated two-thirds of American adults and one-third of children are obese or overweight.
Researchers say that eating snack foods are okay to eat from time to time, it's when we repeatedly overindulge that the problems begin.
