Estudio médico sobre azúcar y fructuosa

 The food industry continues to insist that there is no
difference between high fructose corn syrup (HCFS) and table
sugar, but researchers at Rutgers University have a different
opinion.  They have found new evidence that soft drinks
sweetened with (HFCS) cause tissue damage and may contribute
to the development of diabetes, particularly in children. 
Chi-Tang Ho, Ph.D., and his colleagues conducted tests of eleven
carbonated beverages containing HFCS. He found "astonishingly
high levels of reactive carbonyls" in those beverages. These
highly-reactive compounds associated with "unbound" fructose
and glucose molecules are believed to cause tissue damage. 
Reactive carbonyls are not present in table sugar, whose fructose
and glucose components are "bound" and chemically stable.  The
researchers state that reactive carbonyls are elevated in the
blood of individuals with diabetes and are linked to the
complications of the disease.  
 This study was reported August 23, 2007 at the 234th
national meeting of the American Chemical Society. While we
await further research, I will continue to recommend avoiding
beverages sweetened with HFCS or any other sugars except
during vigorous, prolonged exercise.
