Scientists Find Sugar, Not Fat, to be Reward-Seeking Ingredient

The New York Times’ Well blog reports on a new study published in the American Journal of Clinical Nutrition that has shown that what draws people to treats is sugar, not fat. Researchers recruited 106 healthy teenagers who were asked to sip on milkshakes that varied in sugar and fat content, while in an MRI machine. Researchers found that “while reward centers in the brain were activated in the high fat, low sugar condition, it was the high sugar, low fat condition which seemed to most prominently activate “brain structures as the putamen, insula and rolandic operculum. These brain regions, called the food-reward system, control our desire for food: the more active they are, the more we want to eat.”
