From the study (High-Fructose Corn Syrup: Separating Facts from Myths) Executive Summary:
“Since the 1970s, the use of high-fructose corn syrup (HFCS) in the U.S. food supply has increased dramatically — typically as a replacement for sucrose (table sugar) in soft drinks and many food products. The prevalence of obesity has also increased substantially between the 1970s and the early 2000s. Because of this coincidental timing, HFCS has been erroneously demon-ized as a unique cause of the obesity epidemic in the United States.
Sucrose and HFCS have essentially the same composition, and thus it would be highly unlikely for them to have different effects on body weight or metabolism. Experimental evidence, as well as analyses of epidemiologic data, indicate that sucrose and HFCS have equivalent effects on food intake and therefore on body weight. Scientific evidence does not support the notion that HFCS is uniquely responsible for the American obesity epidemic.”
