Sadly, most people, including doctors and dieticians are unaware how fructose behaves in the body. Patients are advised to refrain from fruit and fruit juices because of the S word (sugar). People with diabetes should rethink the effects of fruit and fruit juices*. Fructose behaves much differently than the glucose in the body after consumption. Consider sugar absorption curves. Glucose ingestion causes a sudden spike (up the Y axis on a graph) from a baseline to extremely high blood sugar levels, a sharp drop off, and eventual reduction of blood sugar to a point BELOW the baseline!! Fructose ingestion, on the other hand, is pretty much a slow consistent absorption that lasts 2 hrs. or more. If graphed it would be a line parallel to the X axis.
* Note. Diabetics wishing to drink fruit juice for health benefits should have a sugar absorption test run to see the effect fruit juice has on their blood sugar levels before changing their diet. This is the report of a study and a brief explanation of body chemistry as it pertains to sugar digestion. It is not to be taken as instruction to eat fruit or drink fruit juice.
