Certain types of food tend to induce digestive discomfort. Many of these contain carbohydrates that are known by the acronym FODMAP. These are not really harmful but consumption in large amounts can trigger undesirable symptoms. It would be hard to completely get rid of them in the daily diet but they can be restricted with mindful meal preparation. This will be much easier if you follow tried and tested low FODMAP recipes.
