A new study conducted using brain imaging tests revealed that high-glycemic foods can trigger parts of the brain that lead to food addiction. This is the same location in the brain that is activated in people associated with substance abuse.
The study, which investigated how food intake is regulated by the pleasure centers of the brain, was led by David Ludwig, a professor of pediatrics at Boston Children’s Hospital. The results, published recently in The American Journal of Clinical Nutrition, suggest that limiting these high-glycemic-index foods could help obese people avoid overeating. “Beyond reward and craving, this part of the brain is also linked to substance abuse and dependence, which raises the question as to whether certain foods might be addictive,” said Ludwig, who is also director of the New Balance Foundation Obesity Prevention Center at the hospital. Food addiction might be real, suggests a new brain imaging studyThe research suggest that not all calories are created equal. Not everyone who eats processed carbohydrates develop uncontrollable food cravings. But for those who have been struggling with weight, the logical step is to limit or even cut out completely all refined and highly processed foods. The study included a dozen people who were either overweight or obese. Participants were given milkshakes. There were two varieties of the drink, one a rapidly digesting high-glycemic index carbohydrate and the other a slow digesting carbohydrate. The results showed that people who consumed faster digesting carbohydrates had a spike in blood sugar levels initially but lower blood sugar levels after just a few hours of consuming the drink. This decrease in sugar levels led to the participants feeling excessively hungry. MRI scans revealed activity in the nucleus accumben region of the brain which is a region associated with addictive behaviors. Brain Addicted to Food with High Glycemic Index - Nature World News
Do High Glycemic Foods Cause Diabetes?This isn't the first study to conclude similar findings. Earlier this year another study showed that people who ate low-fiber and highly processed foods had quick spikes in blood sugars. And this resulted in a significantly higher risks of the most common forms of diabetes. "By raising blood sugar and demanding that the pancreas keep pumping more insulin, meal after meal, day after day, a high-glycemic diet can put people at risk over the edge," said Dr. David Ludwig."
