Hi dollivor,
Most of us ol' timers will tell you to steer clear of the OJ, because not only did he kill his wife, but the sugars will spike your blood glucose too. Useful if you're having a hypo, but otherwise best avoided.
The trouble with fruit juices is that they're really only sugar and water, so the sugars get straight into your bloodstream, whereas the actual fruit itself will do it more slowly because of the fibre etc.
A few of us also avoid eating fruit since the sugars are still too much to control with medication.
Welcome aboard, by the way!
