When I poop, I can see my lunch?

The cell walls of plants aren’t really easily digested by humans. Most grazing animals have a much more intense digestive systems because of this. Think of a cow. Nothing but greens, and it needs 4 stomaches to break it down enough to get the nutrients out of it. They also crap a lot, and have a lot of gas. A lot like what happens to us when we eat green, leafy veggies. Especially if they’re raw. Foods like that are high in fiber/roughage/cellulose. They don’t break down much, and they slide right through us. It’s often the suggested diet, with plenty of fluids, for people who suffer from constipation. There’s absolutely nothing wrong with you. In fact, it’s very common. If you feel fine, don’t have diarrhea, are keeping fluids/food down, and are eating a healthy diet, there’s nothing wrong with you.
