Effects of fructose vs glucose on regional cerebral blood flow in brain regions involved with appetite and reward pathways.

ABSTRACT:

Importance

Increases in fructose consumption have paralleled the increasing prevalence of obesity, and high-fructose diets are thought to promote weight gain and insulin resistance. Fructose ingestion produces smaller increases in circulating satiety hormones compared with glucose ingestion, and central administration of fructose provokes feeding in rodents, whereas centrally administered glucose promotes satiety.

Objective

To study neurophysiological factors that might underlie associations between fructose consumption and weight gain.

Design, setting, and participants

Twenty healthy adult volunteers underwent 2 magnetic resonance imaging sessions at Yale University in conjunction with fructose or glucose drink ingestion in a blinded, random-order, crossover design.<
