Bacon is the perfect FODMAP-free food. It has almost no sugars. Just remember not to add high-FODMAP foods like onions or garlic while cooking it.
High fat and fried foods might still negatively affect your gut if you're sensitive to these factors.
Bacon is a type of salt-cured pork. Bacon is prepared from several different cuts of meat, typically from the pork belly or from back cuts, which have less fat than the belly. It is eaten on its own, as a side dish (particularly in breakfasts), or used as a minor ingredient to flavor dishes (e.g., the club sandwich).
Meat from other animals, such as beef, lamb, chicken, goat, or turkey, may also be cut, cured, or otherwise prepared to resemble bacon, and may even be referred to as, for example, "turkey bacon". Such use is common in areas with significant Jewish and Muslim populations as both religions prohibit the consumption of pork. Vegetarian bacons such as "soy bacon" also exist.
