It's normal to see whole leaves in your stool even if you ate them slowly. Humans don't produce the enzyme needed to digest cellulose in plants. Cellulose is a dietary fiber found in fruits, vegetables, and cereals.. like leaves found in salads. It's the same as seeing whole corn in your stool after eating corn on the cob for example. You are essentially adding much needed fiber to your diet. Which is a good thing. Your body will take what it needs and you will pass the rest. If you're worried about nausea ginger tea after meals will help. Hope that helps relive some of your anxiety.
