Then up to four weeks following that, when the volunteers resumed their normal diet, another six-week diet session would take place with another high-fibre diet, either comprised of more protein, carbohydrates or unsaturated fat.
For fairness, another break afterwards (where people went back to their normal diet) was then followed by another six-week diet experiment.
Participants would report the presence and severity of bloating at baseline levels (when they were eating their own diets) and at the end of each feeding period.
Results concluded that those who eat high-fibre diets are more likely to experience bloating if their high-fibre diet is protein-rich than if it’s rich in carbohydrates or unsaturated fat.
The co-author of the experiment, Noel Mueller said: “Notably, the protein in these diets was mostly from vegetable sources such as beans, legumes, and nuts.”
What are other sources of high-protein foods?
Eggs, chicken and cheese are all sources of protein.
Findings from the study suggest that incorporating more carbohydrates in a high-fibre diet (instead of protein) can help combat bloating.
Carbohydrates are the sugars, starches and fibers found in fruits, vegetables and milk products.
