American-style low-fat, high-fiber diet to reduce gut inflammation in ulcerative colitis
Targeting gut inflammation through diet: a tailored American diet for patients with ulcerative colitis
A low-fat, high-fiber American-style diet with a balanced n-6:n-3 fat ratio to help adults with mild to moderate ulcerative colitis reach remission.

What this research studies
You will follow a personalized American-style low-fat (<3:1 n-6:n-3), high-fiber diet built around foods you prefer. The study compares this tailored diet to a typical Western diet over an eight-week period to see who reaches disease remission. Researchers will collect stool samples to study the microbiome and blood samples to measure polyunsaturated fatty acids before and after the diet. The team will examine whether your baseline microbiome or blood PUFA levels help predict who benefits from the diet.
Who could benefit from this research
Good fit: Adults in the United States with mild to moderate ulcerative colitis who can follow a dietary program and attend clinic visits.
Not a fit: People with severe or fulminant ulcerative colitis, those needing immediate surgery, or those unable to adhere to the diet may not benefit.
Why it matters
Potential benefit: If successful, this could provide a personalized, food-based way to help people with ulcerative colitis achieve remission and lower inflammation.
How similar studies have performed: Small pilot studies and preliminary data suggest low-fat, higher-fiber diets and PUFA-informed approaches can lower inflammation, but larger randomized trials are limited.
