As a general rule of thumb, foods that cause intestinal gas are those that contain carbohydrates and/or soluble fiber. These substances are not easily digested and substantial amounts of partially digested material make their way down to the large intestine where they are acted upon by bacteria; the by-product is gas. Therefore, to avoid gas, you need to eat the opposite -- foods that are not broken down by intestinal bacteria. Here are some safe choices:
1. Protein
- Lean beef
- Fish
- White meat turkey
- White meat chicken
2. Vegetables
The following vegetables are good sources of insoluble fiber:- Greens, such as kale or spinach
- Green beans
- Lettuce
- Tomatoes
3. Fruits
- Berries
- Grapes
- Kiwi
4. Bread
- Gluten-free bread
- Rice bread
5. Rice
Unfortunately, this safe food list is limited. So it is not a good idea to follow as a daily meal plan. Stick to these safe foods only on those days when it is especially important to be gas-free.
