For those living with irritable bowel syndrome (IBS), the daily struggle of bloating, discomfort, and unpredictable digestion can feel exhausting. Finding the right diet to ease symptoms can be frustrating – especially when advice seems to contradict itself. However, a promising new study (2025) from Michigan Medicine suggests that the Mediterranean diet could be a sustainable way to manage IBS symptoms, offering relief without the strict restrictions of other dietary plans.

A dietary approach to managing IBS

IBS is a common gastrointestinal disorder affecting millions worldwide. While medications and lifestyle changes can help, diet plays a huge role in symptom management. Many individuals turn to the low FODMAP diet, which eliminates certain fermentable carbohydrates known to trigger digestive distress. While effective, the low FODMAP diet can be difficult to maintain long-term due to its restrictive nature.

This new study explored whether a Mediterranean diet could provide similar relief while being easier to sustain.

What the study found

Researchers recruited IBS patients and divided them into two groups. One group followed the Mediterranean diet, rich in whole grains, lean proteins, fruits, vegetables, and healthy fats, while the other adhered to a low FODMAP diet, which eliminates foods like onions, garlic, and certain fruits that can cause gas and bloating.

After four weeks, both groups saw improvements. 73% of Mediterranean diet participants reported relief, compared to 81.8% in the low FODMAP group. While the low FODMAP diet had slightly better results, the Mediterranean diet proved effective – and far easier to maintain.

Why the Mediterranean diet?

The Mediterranean diet is widely celebrated for its health benefits, from heart health and cognitive function to reducing inflammation. Unlike the low FODMAP approach, it doesn’t require eliminating entire food groups, making it more balanced and sustainable for long-term health.

Researchers believe this diet’s emphasis on fiber-rich foods, gut-friendly fats, and anti-inflammatory nutrients contributes to its effectiveness in easing IBS symptoms. Olive oil, nuts, fish, and a variety of colorful vegetables provide essential nutrients that support digestion without triggering discomfort.

What this means for IBS patients

While the study was small, its findings suggest a Mediterranean-style diet could be a viable alternative for IBS sufferers who find restrictive diets difficult to maintain. However, IBS is a highly individualised condition, and what works for one person may not work for another. If you’re considering dietary changes for IBS management, consulting a healthcare provider or nutritionist is key.

For those who struggle with digestive issues but want a realistic, balanced approach to symptom relief, the Mediterranean diet may be worth exploring.
