Fructose and its evil twin high fructose corn syrup (HFCS) are used as inexpensive sweeteners in many processed foods, condiments, baked goods and snacks. Researchers at the Oregon Health & Science University publishing in the journal Diabetes, Obesity and Metabolism demonstrate that fructose reacts differently than glucose in the brain causing chemical alterations that lead to increased body weight and obesity.
Brain Response to Fructose is Different Than Glucose
The study involved pre and post meal MRI scans of nine individuals receiving an infusion of fructose, glucose or a saline solution. Researchers found no difference in brain activity in the hypothalamus, an area known to regulate food intake. Activity in the cortical brain control areas showed the opposite response from the sugar infusions. Activity was inhibited with the fructose solution and activated in the presence of glucose.
Fructose Does Not Cause Satiety Similar to Other Macronutrients
The study authors found this to be conclusive evidence that fructose and its derivatives are a significant causative agent responsible for the rampant obesity plague affecting people around the world. In conclusion they write "For consumers, our findings support current recommendations that people be conscious of sweeteners added to their drinks and meals and not overindulge on high-fructose, processed foods."
HFCS has been slowly creeping into the processed food supply over the past 40 years. Health-minded consumers and scientists have theorized that it should be blamed for a contributing role in overweight, morbidity and chronic disease. The best way to avoid high fructose corn syrup is to avoid all processed foods in favor of a raw, natural diet focused on vegetables, lean protein and healthy monounsaturated fats. Your reward will be a healthy, sustainable weight and dramatically lower risk of metabolic disease.
