Recurrent vomiting of undigested food in humans can be caused by various factors, including gastrointestinal obstruction, gastroparesis, or underlying conditions such as pyloric stenosis or gastroesophageal reflux disease (GERD). These conditions can hinder the normal passage of food through the digestive tract, leading to the regurgitation of undigested material. Additionally, certain infections, metabolic disorders, or neurological conditions may also contribute to this symptom. It's essential to consult a healthcare professional for accurate diagnosis and treatment.

By this I assume you mean why you can find pieces of undigested food in feces. Going with this assumption, the reason you find such pieces is because they are indigestible. Bits that are often found in feces include vegetable/fruit skins, seeds, bones, and perhaps even a small coin! Skins often contain a high amount of fiber, which humans cannot digest, and therefore simply pass it out. Seeds are already tough to chew in many cases, and often remain undigested as well. Humans can also not digest bones, and it is not recommended that you eat them because they can puncture the intestine.
