High Fructose Corn Syrup Study Shows Diabetes Link

Researchers have found new evidence that soft drinks sweetened with
high-fructose corn syrup (HFCS) may contribute to the development of
diabetes, particularly in children. In a laboratory study of commonly
consumed carbonated beverages, the scientists found that drinks
containing the syrup had high levels of reactive compounds that have
been shown by others to have the potential to trigger cell and tissue
damage that could cause the disease, which is at epidemic levels. They
reported these findings today at the 234th national meeting of the
American Chemical Society.
HFCS is a sweetener found in many foods and beverages, including non-
diet soda pop, baked goods, and condiments. It is has become the
sweetener of choice for many food manufacturers because it is
considered more economical, sweeter and more easy to blend into
beverages than table sugar. Some researchers have suggested that high-
fructose corn syrup may contribute to an increased risk of diabetes as
well as obesity, a claim which the food industry disputes. Until now,
little laboratory evidence has been available on the topic.
In the current study, Chi-Tang Ho, Ph.D., conducted chemical tests
among 11 different carbonated soft drinks containing HFCS. He found
'astonishingly high' levels of reactive carbonyls in those beverages.
These undesirable and highly-reactive compounds associated with
"unbound" fructose and glucose molecules are believed to cause tissue
damage, says Ho, a professor of food science at Rutgers University in
New Brunswick, N.J. By contrast, reactive carbonyls are not present in
table sugar, whose fructose and glucose components are "bound" and
chemically stable, the researcher notes.
Reactive carbonyls also are elevated in the blood of individuals with
diabetes and linked to the complications of that disease. Based on the
study data, Ho estimates that a single can of soda contains about five
times the concentration of reactive carbonyls than the concentration
found in the blood of an adult person with diabetes.
Ho and his associates also found that adding tea components to drinks
containing HFCS may help lower the levels of reactive carbonyls. The
scientists found that adding epigallocatechin gallate (EGCG), a
compound in tea, significantly reduced the levels of reactive carbonyl
species in a dose-dependent manner when added to the carbonated soft
drinks studied. In some cases, the levels of reactive carbonyls were
reduced by half, the researchers say.
"People consume too much high-fructose corn syrup in this country,"
says Ho. "It's in way too many food and drink products and there's
growing evidence that it's bad for you." The tea-derived supplement
provides a promising way to counter its potentially toxic effects,
especially in children who consume a lot of carbonated beverages, he
says.
But eliminating or reducing consumption of HFCS is preferable, the
researchers note. They are currently exploring the chemical mechanisms
by which tea appears to neutralize the reactivity of the syrup.
Ho's group is also probing the mechanisms by which carbonation
increases the amount of reactive carbonyls formed in sodas containing
HFCS. They note that non-carbonated fruit juices containing HFCS have
one-third the amount of reactive carbonyl species found in carbonated
sodas with HFCS, while non-carbonated tea beverages containing high-
fructose corn syrup, which already contain EGCG, have only about one-
sixth the levels of carbonyls found in regular soda.
In the future, food and drink manufacturers could reduce concerns
about HFCS by adding more EGCG, using less HFCS, or replacing the
syrup with alternatives such as regular table sugar, Ho and his
associates say. Funding for this study was provided by the Center for
Advanced Food Technology of Rutgers University.
