Appetite Heightened By Ingestion Of Fructose - Health News - redOrbit

A new study from Yale University School of Medicine examines possible factors regarding the association between fructose consumption and weight gain.

The researchers used brain magnetic resonance imaging, which indicated that ingestion of glucose but not fructose reduces cerebral blood flow. Activity in brain regions that regulate appetite was also reduced. The participants reported an increase in feeling sated and full from the ingestion of glucose but not fructose.

“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,” according to the authors. “Thus, fructose possibly increases food-seeking behavior and increases food intake.”
