Fructose is another type of sugar that the liver breaks down. In fact, the liver is the only organ that is capable of processing fructose. Fruits and honey contain natural fructose which is healthy and nutritious in moderate amounts. However, when people consume unnatural fructose, such as high fructose corn syrup, the liver will store it as new fat. This is because high fructose corn syrup is a processed form of fructose that the liver cannot break down properly. Ideally, this new fat should be excreted by the body but this does not happen in individuals whose diet is unhealthy. Instead, the extra fat will accumulate in the liver cells, leading to fatty liver disease.
