Undigested food can remain in the body for varying periods, depending on several factors such as the type of food, individual metabolism, and digestive health. Typically, food moves through the digestive system in about 24 to 72 hours, but certain fibrous or high-fat foods may take longer to digest fully. If food remains undigested for an extended period, it can lead to discomfort, bloating, or other digestive issues. Consult a healthcare professional if you experience persistent digestive problems.

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.
