Getting what nutritional value it can and pooping out the rest is just literally what eating is.

I think the point is in comparison to some animals, we don't extract the full amount of nutrition available in plants (which requires a much larger gut and more energy digesting).

[frankhorrigan]

Still an absurd argument. We get a lot of nutritional value from plants and you still take shits after eating meat.

We generally don't eat the toughest parts of plants either. Seeds and fruits are not as hard to digest as many stems or plants like grass. Not to mention that we pre-process a lot of the vegetable matter we eat - either by grinding (e.g. flour) or cooking or both.

Thankfully humanity invented cooking for this very reason. Progress is great, isn't?
