Anti-sugar advocates have long blamed a type of sugar called fructose for many of our nutritional woes.

One Australian expert says this new research shows how fructose "gets under the satiety radar", importing calories without sending signals to our body that we have eaten.

Study leader Kathleen Page, a doctor and an assistant professor of medicine at the Keck School of Medicine at the University of Southern California, said her research could have important public health implications because it essentially showed that fructose may encourage "feeding behaviour".
