9. Liver Problems
Sugar is really hard on your liver as well. It is actually comprised of an approximately 50/50 split of glucose and fructose.
Glucose is used by cells to produce energy, but fructose is not immediately useful to cells. It must be metabolized by the liver first, and the liver can only handle so much fructose at once. Excess is converted in uric acid and triglycerides.
Just one can of soda is enough to overwhelm the liver and force it to create fat, and when this process is chronic, small droplets of fat will form in the liver. The condition is called non-alcoholic fatty liver disease (NAFLD), and it causes chronic fatigue, abdominal swelling, and jaundice.
