It’s a well-known fact that sugar is bad for your health, but to what extent? To answer this, you need to know that there’s more than one type of sugar. Glucose, the ‘good’ sugar, is needed to for the circulation of the blood, as well as the secretion of insulin. Fructose on the other hand is the 'bad sugar', and can only be metabolized by the liver. Once the liver has too much fructose to handle, it is turned into fat rather than energy, and nobody wants that!
