if humans can't digest cellulose ,so how can we digest leafy vegetables?

Answer 1

The human digestion system disrupts the cell walls and membranes of the leafy vegetables allowing the nutrients to be released and later absorbed.

Part of this process is physical (chewing) and part is chemical (both enzymes and hydrochloric acid in the mouth and stomach).

The cellulose in the cell walls passes through the system undigested as fiber or "roughage." This is true for other plant materials like corn hulls, not just green leafy vegetables.

Answer 2

You can digest other parts of the leafy vegetables, but not the cellulose. The cellulose just passes through your digestive system ans firms up your stool. Hope that helps.

Answer 3

We don't digest them completely. We break down the vegetables and we do get nutrients out of the cells. But the cellulose in the cell walls of plant tissues, we don't digest at all. That stuff goes right through us.

Answer 4

We digest parts of the leafy vegs for its nutrients but not the cellulose. The cellulose is necessary in our diets for its fiber.

Answer 5

So then, why can't we eat bark? Or certain plants?

Why can we eat only certain vegetables?

I heard that the appendix used to help us with this but never got a good explanation on why some greens are okay and not others.

This isn't much of an answer but I wasn't sure where else to post it.
