What is the link between ultra-processed foods and Crohn's disease?

High consumption of ultra-processed foods is consistently associated with a greater risk of developing Crohn's disease, according to a new study.

How do ingredients in ultra-processed foods affect the gut?

Ingredients like emulsifiers and maltodextrin can damage the gut lining, alter the microbiome, and lead to inflammation, contributing to IBD issues.

Can diet changes help manage Crohn's disease?

Yes, reducing ultra-processed foods and focusing on whole, nutrient-dense foods may help in managing and reducing the risk of developing Crohn's disease.

High ultra-processed food intake associated with increased Crohn's disease risk.
Certain ingredients in processed foods can damage gut barrier and cause inflammation.
Dietary changes may help manage or reduce Crohn's disease development.

Ultra-Processed Foods Linked to Crohn's Disease

A recent analysis of scientific literature indicates a significant correlation between increased consumption of ultra-processed foods and a higher risk of developing Crohn's disease. This research synthesized findings from studies conducted between January 2010 and March 2025, focusing on epidemiological data, underlying mechanisms, and therapeutic approaches.

The study specifically noted that certain ingredients prevalent in ultra-processed items, such as emulsifiers and maltodextrin, can compromise the gut's epithelial barrier, disrupt the microbiome, and instigate inflammation. This mechanistic understanding offers insight into why these foods may contribute to inflammatory bowel disease.

While the association with ulcerative colitis was less pronounced, the evidence strongly suggests that dietary choices, particularly the reduction of ultra-processed foods, can play a vital role in both preventing the onset of Crohn's disease and managing existing symptoms. Experts emphasize that these dietary shifts, alongside other lifestyle adjustments, are essential for gut health.
