It is not confusing at all, and all necessary info can be obtained from the inet. To sum it all up: 1. Fruit contains solube and insoluble fiber in about equal amounts. 2. Humans (like other primates) do not have enzymes to break down cellulose; however, human gut bacteria can, to an extent (extimated ~10% of total energy intake), digest fiber and will produce fuel that can be used by the gut (short chain fatty acids), but much less so than other primates (i.e. chimps and gorillas who mostly subsist on energy from fiber, i.e. upto ~60% of total energy).
Whereas soluble fiber will enter circulation and leave the system again, unaltered.
