Fruit is not inherently bad, there are just some things you need to know. Fructose, a primary sugar in fruit, is not quite as user-friendly in the human body as glucose. It is easily stored as fat and can be problematic for the liver. In fact, high fructose corn syrup has basically the same effect on the liver as the ethanol alcohol found in your favorite adult beverage. In nature, however, we find fructose present with fiber which slows its absorption and eases the load on the liver, making it less problematic to consume, but still quite easy to store.
