Using imaging tests, Scientists have shown that the sugar “fructose” can trigger brain changes that may lead to overeating.
According to a recent study published in the Journal of the American Medical Association, reseachers found out that the brain does not register as “being full” after drinking beverages containing fructose like it does when simple glucose is consumed.
The study showed that drinking glucose “suppresses” the area of brain activity that desires food. However, with fructose, these changes are not seen, and as a result, the desire to eat is still there.
Fructose and high-fructose corn syrup are usually added to foods and beverages that are processed, which may be why 1/3rd of children and teens and 2/3rds of adults in the United States are overweight.
All sugars may contain the same number of calories but they are metabolized by the body differently. For example, high-fructose corn syrup is 55% fructose and 45% glucose. Table sugar (sucrose) is 50% fructose and 50% glucose.
