The process of juicing any fruit means breaking down and often removing the fiber, which leads to free sugars that are easily and quickly absorbed into the blood. Even if the fiber remains, it is no longer enclosing the sugar so any benefit is removed. That is the entire problem with juice and most any drink that contains large amounts of sugar. The process of digesting whole fruit is slow and difficult and causes the sugar to be released slowly, which is what avoids the health problems associated with sugary drinks. This is why juice is essentially the same as soda in this regard. Whether juice bars are a trend or not is really irrelevant to the issue, and it would not be the first time someone tried to sell people things that were bad for them under the guise of it being healthy.
