Fructose Fails to Satisfy
Hungry? You might want to skip the fructose. Researchers monitored the brains of healthy volunteers who consumed either glucose or fructose. The sugars had different effects on the brain. Glucose cut down on blood flow to brain regions associated with appetite, but fructose didn’t. In addition, fructose triggered a smaller rise in hormones associated with feeling satisfied after eating, such as insulin and GLP-1. The findings suggest that food products that use fructose as a sweetener may contribute to weight gain by encouraging people to overeat.
