I think I understand, this is good to know. I admit I had assumed that all the sugar in fruit was fructose. A table I found says that apple juice is 56% fructose, so in that case it's not a very efficient hypo treatment, but my experience is that it works! When I drink 100 ml apple juice (10 g sugar) it seems to behave just like 10 g Dextrosol tablets, but a bit quicker. If I am only getting 5g of hypo treatment I am surprised at the effect!The sugars in OJ are sucrose, half glucose, half fructose.
The glucose content in the OJ treats the hypo and registers on the meter. The fructose doesn't treat the hypo, or registers. It has to be metabolised by the liver, like alcohol and turned to fat.
