That high-fructose corn syrup (HFCS) causes weight gain is not surprising; that it leads to a significantly higher weight gain than regular table sugar, even when overall caloric intake is the same? Surprising. Regardless of how innocent the sensitive souls from the Corn Refiners Association may purport HFCS to be, a Princeton University research team begs to differ with new research demonstrating that all sweeteners are not created equal in terms of weight gain.
In addition to causing considerable weight gain in lab tests, long-term consumption of high-fructose corn syrup also led to abnormal increases in body fat, especially in the abdomen, and a rise in circulating blood fats called triglycerides. The researchers say the work sheds light on the factors contributing to obesity trends in the United States.
“Some people have claimed that high-fructose corn syrup is no different than other sweeteners when it comes to weight gain and obesity, but our results make it clear that this just isn’t true, at least under the conditions of our tests,” said psychology professor Bart Hoebel, who specializes in the neuroscience of appetite, weight and sugar addiction.
The results were published March 18 by the journal Pharmacology, Biochemistry and Behavior, the researchers from the Department of Psychology and the Princeton Neuroscience Institute reported on two experiments looking into the connection between the use of high-fructose corn syrup and obesity. They noted that they do not know why HFCS led to more triglycerides and more body fat that resulted in obesity.
