And now, instead of more grumbling about government's handling of the economy, something completely different. I'll try not to get too scatalogical in today's post. The human body is an incredibly sophisticated, complex organism. Humans are omnivores, capable of eating a wide variety of things for food sources. Anything we eat or drink that the body cannot use passes through the body and is exited as either liquid or solid waste. But what if you could eat only food sources that the body could completely use?
If there was no unnecessary food item in your diet, then you would not need to go to the restroom. Is such a food possible? Is it desirable?
To make it possible, you would need to eat the right kind of food products, the kind your body can effectively and efficiently make use of, and you would need to eat the right amount that your body needs. I suppose if you ate more, your body could save some of it as fat instead of getting rid of it, but that's not especially desirable either.
I don't think there are any 'natural' foods that wouldn't produce waste. Certainly, switching to a low carb diet has changed my own waste. So I imagine that we would need to come up with some kind of processed food to be the "perfect", waste-free food. That would entail knowing exactly what the body needs and doesn't need so that we can avoid what we don't need. I don't think the nutrition experts know enough about the human diet to do that. At least not yet. And it would be complicated by the fact that your body needs different things at different times, so it wouldn't just be a static variable every time.
Of course, even if it's possible, there's the question of how desirable it is. It seems pretty obvious to me that we could save time, water, and toilet paper (and have fewer plumbing problems) if we didn't need to go to the restroom. You'd never again be standing in line or waiting somewhere, squirming in discomfort until you were free. That seems pretty desirable to me.
However, what would happen to your body without passing waste products? Think of fiber, for instance. People are encouraged to eat more fiber so that they will be more "regular", but other than that, I don't think the body has much use for fiber. That's why fiber can be subtracted when calculating "net carbs" in a diet--the fiber doesn't count. Of course, if you don't have anything else to pass, then you'd be doing nothing but eating fiber to pass fiber through your body, which seems pointless.
Nonetheless, your intestines, kidneys, etc. might need some occasional waste to process to keep them functioning properly. I'm not sure medical science knows enough to say for sure (or maybe nobody's asked them such a silly question!).
This is just one of those weird ideas I come up with every now and then. I don't have any answers for it. Maybe you do.
