Stomach bloating is the end result of too much gas filling up your gastrointestinal tract (GI). The GI tract is a series of hollow organs joined in a long, twisting tube from the mouth to the anus. You can usually remedy a puffy, stretched stomach by cutting out certain foods known to cause bloating.
Conversely, increasing your intake of certain foods can also help to expel gas.
For example, if your bloating is caused by constipation, adding more fibre to your diet may help to move things along, according to the NHS.
Research suggests there are some caveats to consider before eating a high-fibre diet, however.
According to findings published in the Clinical and Translational Gastroenterology, people who eat high fibre diets are more likely to experience bloating if their high fibre diet is protein-rich as compared to carbohydrate-rich.

The findings thus also hint at a role for “macronutrients” such as carbs and proteins in modifying the gut bacteria population – the microbiome.
The microbiome is the general term for the trillions of bacteria, viruses and fungi living in your body.
“It’s possible that in this study, the protein-rich version of the diet caused more bloating because it caused more of a healthy shift in the composition of the microbiome,” said study co-senior author Noel Mueller, PhD, an assistant professor in the Department of Epidemiology at the Bloomberg School.
He continued: “Notably, the protein in these diets was mostly from vegetable sources such as beans, legumes, and nuts.”
General dietary tips
It is quite possible that a food intolerance could be triggering your bloating.
According to the NHS, food intolerance can lead to bloating when:
- Your bowel does not empty properly
- The food causes gas to be trapped
- Too much gas is produced as a reaction to the food
“The best approach if you have a food intolerance is to eat less of the problem food or cut it out completely,” advises the health body.
It also says to keep a food diary for a couple of weeks, noting everything that you eat and drink and when bloating troubles you most.
