While the influence of sweet taste on neurocognitive function has been widely studied, umami or savory has received less of a research focus. Animal models and even some small human studies seem to show that umami given in a broth before a meal can influence appetite and food intake. And this inspired Dr. Miguel Alonso-Alonso, Assistant Professor and Director of the Laboratory of Bariatric and Nutritional Neuroscience at Beth Israel Deaconess Medical Center and Harvard Medical School. He and his colleagues decided to test the influence of glutamate on behavior and food choice, as well as the neurocognitive mechanisms that might be affecting such behavioral changes.
