I don't have an explanation for the experience of digesting food at the cellular level either. But I still do it. You don't have to explain conciousness to have it.
As for qualia, I'm reminded of the people coming to my door asking, "Do you believe in Jesus?" I reply, "Do you?" and when they assure me fervently that they do, I follow up with, "Well, okay, how do you know you do?" I think you could do the same with r/Jesus/qualia/g.
