The Claim

High consumption of ultra-processed foods is associated with alterations in gut microbiota composition and immune cell signaling pathways, which may contribute to increased risk of inflammatory and autoimmune conditions, though direct causal evidence in humans remains unestablished.

In plain English

High intake of ultra-processed foods is linked to changes in gut bacteria and immune cell signaling, and is associated with a higher incidence of inflammatory and autoimmune conditions.

See the scientific wording

High consumption of ultra-processed foods is associated with alterations in gut microbiota composition and immune cell signaling pathways, which may contribute to increased risk of inflammatory and autoimmune conditions, though direct causal evidence in humans remains unestablished.

Why this might work

Eating ultra-processed foods changes the bacteria in the gut and damages the lining of the intestines. This lets bacterial parts leak into the tissue underneath, which triggers immune cells to activate a specific inflammatory pathway. These immune cells then multiply and release signals that cause ongoing inflammation in the gut and throughout the body.

  1. Study: Ultra-processed foods: increasing the risk of inflammation and immune dysregulation?

    This study says that eating lots of ultra-processed foods might mess up the good bacteria in your gut and confuse your immune system, which could make you more likely to get inflamed or sick — but it doesn’t prove it definitely causes those problems yet.
