Non-alcoholic fatty liver disease is the build up of extra fat in the liver that is not caused by alcohol.
One-third of Americans - sixty million people - who have no history of significant alcohol consumption have fatty livers.
Research shows two things in the American diet cause the storage of fat in the liver: fructose (sugar) and omega-6 fats (found in vegetable oils).
Fat in the liver causes fat around your middle. It can also lead to cirrhosis, liver failure or liver cancer. A fatty liver often goes hand in hand with diabetes.
Studies at Duke and Cambridge University found that subjects who went on a low-carbohydrate, high-fat and high-saturated fat diet quickly reduced the amount of fat in their livers.
