What you eat can either help calm inflammation or fuel it. A recent study highlights how pro-inflammatory diets are linked to more severe cases of Crohn’s disease and ulcerative colitis. Here’s a closer look.
What is IBD?
IBD covers Crohn’s disease and ulcerative colitis, two chronic conditions that inflame the digestive system and cause painful symptoms.
Why diet matters
Researchers in Poland found that people with more anti-inflammatory diets had milder symptoms, while those eating pro-inflammatory foods often experienced worse flare-ups.
Red meat
High amounts of beef, pork, and lamb can trigger inflammation and worsen gut sensitivity.

Processed meats
Sausages, bacon, and deli cuts often contain additives that can stress the digestive tract.
Sugary drinks
Sodas and energy drinks disrupt blood sugar balance and gut bacteria, making flare-ups more likely.
Fried foods
Heavy, greasy meals are difficult to digest and can irritate an already inflamed intestine.
Ultra-processed snacks
Packaged chips, cookies, and ready meals are linked to higher inflammation scores.

Refined grains
White bread and pastries lack the nutrients and fiber found in whole grains, leaving the gut more vulnerable.
Dairy in excess
Cheese and cream may worsen diarrhea, cramps, and bloating for some people with IBD.
Alcohol
Drinking weakens the intestinal lining and raises inflammation throughout the body.
Artificial sweeteners
Some sugar substitutes disturb gut microbiota, increasing the risk of symptom flare-ups.

The role of inflammation
The study measured each participant’s Dietary Inflammatory Index (DII), showing how certain foods can either calm or fuel inflammation.
Fiber confusion
While fiber can be healthy, some people with IBD find it makes symptoms worse during flare-ups.
The microbiome connection
IBD patients often have an altered gut microbiome, which may explain why diet affects them more strongly.
Cytokines and the immune system
Researchers tested blood samples for inflammation markers, showing how diet interacts with immune responses.

Mediterranean diet
Experts recommend more fruits, vegetables, fish, and whole grains, which are naturally anti-inflammatory.
Omega-3 benefits
Foods rich in omega-3 fatty acids, like salmon and walnuts, may help lower inflammation levels.
Processed food risks
Favoring ultra-processed diets has been linked in studies to higher risk of developing Crohn’s disease.
Lifestyle matters too
Alongside diet, factors like smoking, exercise, and stress also influence how IBD develops.

Why balance is key
No single food causes IBD, but overall eating patterns make a big difference in whether symptoms are mild or severe.
