This topic is about understanding why certain beans, specifically black beans, might behave differently in the digestive system of someone with an ostomy. The person sharing their experience has noticed that while they can eat baked beans, butter beans, and other types without any trouble, black beans seem to pass through almost undigested, with the skins appearing in their pouch. They are curious about why this happens and are seeking advice.

Here are some helpful insights and advice:

1. The thickness of the bean skins might be the reason. Black beans, like kidney beans, have tougher skins that might not break down completely during digestion.

2. It's important to remember that how your body reacts to food can change. A food that is fine one day might cause issues another time.

3. If you want to try black beans again, consider starting with a very small portion to see how your body handles it.

4. Since there was a previous experience with a bowel obstruction, it's wise to be cautious with food choices. It's not always clear what might trigger a blockage, so taking it slow with new or problematic foods is a good approach.
