Out of all the outrageous things in that filler, this was probably the only thing that makes sense. We know for a fact that the Shinju feeds on blood, but we've also seen that the Juubi could absorb and control nature energy, the same for Kaguya. It only makes sense that this nature energy control comes from the Shinju. it would also explain why a planet only has one (else it dies out too quickly). It would also explain why Momoshiki's planet was barren, after all if it produced nature energy, why would it die?

So there is propability that tree absobrs most of natural energy or even all of it. Trees produce fruit in order to spread. The fruity part is to attract animals, whereas the hard seeds within aren't digested and so spread. It seems that the Shinju does a similar thing. After all, once the Otsutsuki obtained this power they apparently spread the shinju across the universe. And it's the Shinju's power that allows the fruit's eater to traverse said universe. It could also explain why Kaguya absorbed the tree at all, so it could evolve to a more mobile form.

And it could explain why the Otsutsuki don't eat the fruit, so they can actually plant new shinju.
