Secondly, eating fruit and eating sugar are two very different things. Fruit has things like nutrients and fiber that is lost in processing, which is likely the root of the disorder. The fiber, for example, slows down the absorption of sugars. The modern world is full of highly refined sugars that are missing the goodness found in nature (that our bodies adapted to).
