Not all foods break down at the same rate, and some can linger longer in your stomach, causing bloating, gas, and discomfort—especially if your gut is already sensitive.

Let’s look at some examples:

  • Apple: digests in 40 minutes—great for a light snack.

  • Egg: takes 2 and a half hours—nutrient-dense but moderate.

  • Avocado: 2 hours—healthy fats, but consume mindfully.

  • Almonds: 3 hours—nutrient-rich but heavy if overdone.

  • Chicken: 3 and a half hours—lean protein, but slower to digest.

  • Cheese: nearly 5 hours—one of the slowest, often troublesome for SIBO.

  • Red meat: almost 4 hours—another dense protein that takes time.

  • Fish: 90 minutes—an excellent, easy-to-digest protein.

  • Milk: about 2 hours, though lactose can be an issue.

  • Pasta: 1 and a half hours—a quick carb, but often with gluten.

  • Oats: between 1 and a half and 2 and a half hours—a good carb, but moderate.

  • Lentils: nearly 3 and a half hours—fiber-rich, but highly fermentable.


Being mindful of these digestion times is crucial: slower-digesting foods can worsen bloating and discomfort in SIBO patients. Opt for faster-digesting proteins, light carbs, and pay close attention to how your body reacts.
