Some people have trouble saying no to sweets. Now a group of scientists from Toronto Canada may have discovered part of the reason why.
In a study from May 2008, researchers found that people with a certain DNA difference in their SLCa2 gene ate more sugar than people with other versions.
A Sugary Gene – The SLCa2 gene has the instructions for making the GLUT2 protein. he results suggest that one small change in GLUT2 causes some people to eat more sugar.
People with an Isoleucine (Ile) at 110 Eat More Sugar.
This research suggests that having an Ile at position 110 of the GLUT2 protein gives people a sweet tooth.
