Fructose is actually produced in the brain, new study finds

Fructose is a simple monosaccharide found in many fruits and vegetables, where it is often bonded to glucose. Pure, dry fructose is a very sweet, white, odorless, crystalline solid and is the most water-soluble of all the sugars. Because of its properties, it’s often added to processed and baked foods, to make them sweeter and tastier — but excess consumption contributes to high blood sugar and chronic diseases like obesity. A previous study had already shown that fructose and glucose have a significant effect on the brain, but it wasn’t clear if the fructose was produced in the brain or simply arrived there through the bloodstream.To answer this question, researchers gave eight healthy participants infusions of fructose and glucose, while measuring sugar concentrations in their brains and bodies using a non-invasive technique called magnetic resonance spectroscopy. They found that when participants drank the glucose infusion, their fructose levels in the brain rose dramatically while levels in the brain remained relatively low.
