The Claim

Higher habitual intake of ultra-processed foods in Korean adults with inflammatory bowel disease is associated with a shift in gut microbiota composition characterized by increased abundance of pro-inflammatory bacterial taxa such as Escherichia-Shigella, Proteus, and Fusobacterium, and decreased abundance of anti-inflammatory commensals like Faecalibacterium and Bifidobacterium.

In plain English

In Korean adults with inflammatory bowel disease, a diet high in ultra-processed foods is linked to higher levels of certain bacteria linked to inflammation and lower levels of bacteria linked to reduced inflammation.

See the scientific wording

Higher habitual intake of ultra-processed foods in Korean adults with inflammatory bowel disease is associated with a shift in gut microbiota composition characterized by increased abundance of pro-inflammatory bacterial taxa such as Escherichia-Shigella, Proteus, and Fusobacterium, and decreased abundance of anti-inflammatory commensals like Faecalibacterium and Bifidobacterium, suggesting a microbial profile linked to intestinal inflammation.

Why this might work

Eating a lot of ultra-processed foods like sugary drinks and packaged snacks feeds harmful bacteria in the gut while starving beneficial ones. These harmful bacteria produce toxic chemicals that damage the gut lining and trigger inflammation. At the same time, the good bacteria that normally calm inflammation stop making their protective chemicals. This creates a cycle where the gut becomes more inflamed and less able to heal.

  1. Study: Habitual Ultra-processed Food Intake Is Associated with Gut Dysbiosis and Pro-inflammatory Metabolite Profiles in Korean Patients with IBD.

    In people with IBD, eating more junk food like sugary drinks and packaged snacks was linked to more harmful gut bacteria and fewer helpful ones, which may make their gut inflammation worse.
