With an object-oriented model of reality, then yes, you can say there is a single banana object instance whose coordinates mutate to remain inside your body, and gradually your body decrements the banana nutrient counters while incrementing its own.
With a value-based model of reality, it doesn't happen that way. In that model, a both you and the banana are modeled as the (time, place, nutrients) triple of immutable values. Those triples never "change" or "become old" or "get duplicated". They just are.
At 4 o'clock, my nutrient counters were low and the banana had coordinates similar to mine but not quite. At 5 o'clock, my nutrient counters were higher and the banana had coordinates equal to me. Both of these statements are valid at the same time with no conflict.
Similarly, I don't get where this "if I open the boot of my car do I now have two cars" is coming from. <Chevrolet, 8:41 AM, Boot closed> and <Chevrolet, 8:42 AM, Boot opened> coexist in peace. They're not two different car objects, they're two different immutable, factual descriptions of states. As long as they were correct in the first place, the will never become incorrect or change in any way.
