Addicted to chocolate? 
A new study, published last week in the American Journal of Clinical Nutrition shows that certain types of foods may actually be addictive.

The project was led by David Ludwig, MD, PhD, the director of the New Balance Foundation Obesity Prevention Center of Boston Children's Hospital.

Using MRI studies to compare the effects of high glycemic index foods with lower ones, on the brain, scientists were able to see the addictive effects certain foods can have.

"These findings suggest that limiting high-glycemic index carbohydrates like white bread and potatoes could help obese individuals reduce cravings and control the urge to overeat," Ludwig said while commenting on the findings.

The study furthers the concept that certain foods may actually be physically addicting.

However, additional research is necessary for full understanding.
