New brain scan research supports the notion that some people have a food "addiction," with foods like white bread or potatoes helping to spur their craving to eat.
Researchers used functional ("real time") MRI to observe the brain activity of 12 overweight or obese men during the crucial four hours after they ate a meal, a period that experts say influences eating behavior during the next meal.
The participants' blood sugar levels and hunger were also measured during this time.
The men's "meals" were two milkshakes that had the same calories, taste and sweetness. The only difference was that one milkshake contained high-glycemic index carbohydrates and the other had low-glycemic index carbohydrates.
High-glycemic index carbohydrates -- which are quickly transformed into sugar in the blood -- are found in highly processed foods such as white bread and white rice. Low-glycemic index carbohydrates are found in items such as whole wheat products and sweet potatoes.
The researchers found that consuming carbohydrates like those found in processed foods can cause excess hunger and stimulate areas of the brain involved in reward and cravings, regions that also play a role in addiction, according to the study published June 26 in the American Journal of Clinical Nutrition.
