  7. 8. The perception of fruit juice as equal in health benefit to fresh fruit has been questioned, mainly because it lacks fiber and has often been highly processed. High-fructose corn syrup , an ingredient of many juice cocktails, has been linked to the increased incidence of type II diabetes.

Unlike many people think there is not a whole lot of fruit flesh lost when you squeeze fruit. This means that your glass of orange juice does contain all the fibers you need! These fibers prevent from many diseases. Fibers stimulate the digestive system so if you have a substantial amount of fruit intake it is not necessary to eat bran or other intestine stimulating foods.
