The Claim

Higher intake of 7-ketositosterol, a phytosterol oxidation product primarily found in ultra-processed fried and baked foods, is associated with increased disease severity in patients with ulcerative colitis and Crohn’s disease, as measured by colonoscopy, histology, and fecal calprotectin levels.

In plain English

Higher consumption of 7-ketositosterol, a compound formed in ultra-processed fried and baked foods, is linked to more severe inflammation in the intestines of people with ulcerative colitis or Crohn’s disease, as shown by colonoscopy, tissue analysis, and fecal calprotectin measurements.

See the scientific wording

Higher intake of 7-ketositosterol, a phytosterol oxidation product primarily found in ultra-processed fried and baked foods, is associated with increased disease severity in patients with ulcerative colitis and Crohn’s disease, as measured by colonoscopy, histology, and fecal calprotectin levels, suggesting a dietary component may influence inflammatory bowel disease progression.

Why this might work

Eating fried and baked foods high in 7-ketositosterol changes the gut bacteria, causing a specific bacterium to multiply. This bacterium releases a protein that latches onto a receptor in the gut lining, turning on a chain reaction that floods the tissue with inflammatory chemicals. These chemicals break down the protective barrier of the gut, allowing more damage and swelling, which makes bowel disease worse.

1 study

  1. Study: Ultra-processed foods sourced 7-ketositosterol aggravates colitis through gut dysbiosis induced-PDLIM3 activation

    People with bowel diseases who ate more fried foods had more of a chemical called 7-ketositosterol in their blood, and their guts were more inflamed. In mice, this chemical made gut inflammation worse by changing gut bacteria and turning on inflammation signals.
