This topic is about finding low-odor sandwich and snack options for colostomy patients, especially when flying. The goal is to avoid foods that might cause embarrassing odors during a flight, as experienced by one person after eating a full English breakfast. Here are some practical suggestions to consider:

1. Avoid foods that are high in protein and sulfur, such as eggs and beans, as they tend to produce strong odors.

2. Opt for meals that are lower in total protein to help reduce waste and odor.

3. Peanut butter is a popular choice:
- Consider a peanut butter sandwich or peanut butter on a bagel or white toast.
- It provides calories, is easy to pack, and many find it doesn't cause immediate output.

4. Other sandwich or travel-friendly ideas include:
- Plain pasta or pasta salad.
- Cold cuts with modest protein like ham, chicken, or bacon, used sparingly.
- Banana, rice, or tapioca pudding cups, if you're not lactose-intolerant.
- Nutella can be a good alternative spread if peanut butter isn't preferred.

5. For odor control, taking 2 Beano tablets (an over-the-counter enzyme supplement) before meals that might cause gas can be helpful. Many users find it significantly reduces odor, even after eating foods like sauerkraut.
