How Fructose in Soda Causes Obesity

Tuesday, 28 February 2012 11:48 AM

High-fructose corn syrup – used to sweeten sodas, other beverages and baked goods – has long been known to be a key contributor to obesity, diabetes and other health problems. Now a team of scientists has determined how.
In a study published in the journal Proceedings of the National Academy of Sciences, researchers found that fructose can be metabolized by enzymes that can cause fatty liver, obesity, and insulin resistance – a hallmark of diabetes.
Dr. Richard Johnson, lead author of the study and a University of Colorado School of Medicine specialist, said the findings are significant because they provide a better understanding of how fructose causes obesity and other illnesses. They may also provide a clue to why some people may be more vulnerable to the negative effects of fructose than others.

"These studies provide new insights into how fructose may contribute to the development of obesity and diabetes,” he said. “In particular, the identification of contrasting roles for two enzymes that are involved in fructose metabolism was surprising and could be important in understanding why some individuals may be more sensitive to the metabolic effects of fructose than others."

Studies have shown that fructose in added sugars -- such as sucrose and high-fructose corn syrup -- is strongly linked to the nation’s epidemic rise in obesity, diabetes and fatty liver disease.

The new research found fructose can be metabolized by an enzyme that exists in two forms. One form is linked with fatty liver, obesity, and insulin resistance; the other form may actually protect people from developing these features in response to sugar.

Understanding the differences “may provide important insights” into the risks posed by fructose and how best to combat them, researchers said.
