The rats preferred the one made with sucrose over the one with maltodextrin, and when they received sucrose, they'd lick it faster. To study this question, researchers gave rats two similar sugary drinks. Even if we can have both, Ottenheimer says, the dish that's the favorite will likely be eaten faster and with bigger bites.
BRAIN BUFFET MAC
This might seem automatic as you move down a buffet line, but when someone is considering either mac and cheese or mashed potatoes, the brain must quickly determine which of those quite similar choices - both tasty, both treats, both carbs - would be most rewarding. It's a situation people face daily, if not at buffets or potlucks, then when looking over restaurant menus or at what's in the refrigerator. The research team wanted to know how the brain determines what and how much to eat when someone has several good food options. "The level of brain activity we saw exceeded our expectations by far." "We found a region in the brain that reflects our perception of food in a strikingly dominant way," said lead author David Ottenheimer, a Johns Hopkins University graduate student studying neuroscience. The findings are set for publication in the journal Nature Communications. The finding suggests this brain area could be key to developing therapies and treatments to encourage healthy eating. Researchers, working with rats, found robust neural activity related to food choice in a previously overlooked part of the brain.
