Not That You Needed Confirmation, but There Is Such a Thing as #Food Addiction
Did you ever feel as if you were just addicted to certain foods? Well, there’s a good chance that it’s true. According to research from Boston Children’s Hospital appearing in the American Journal of Clinical Nutrition, substance abuse and eating high-glycemic foods may trigger the same brain mechanism tied to addiction.
Researchers had 12 overweight men consume milkshake meals, the only difference being that one group consumed rapidly digested (high-glycemic index) carbohydrates, and the other group consumed slowly digested (low-glycemic index) carbohydrates.
The researchers then measured “blood glucose levels and hunger, while also using functional magnetic resonance imaging (MRI) to observe brain activity during the crucial four-hour period after a meal, which influences eating behavior at the next meal.”
The results? “After participants consumed the high-glycemic index milkshake, they experienced an initial surge in blood sugar levels, followed by a sharp crash four hours later. This decrease in blood glucose was associated with excessive hunger and intense activation of the nucleus accumbens, a critical brain region involved in addictive behaviors.”
The authors of the study suggest that limiting high-glycemic index carbohydrates like white bread and potatoes could reduce overall urges.
