Randomized trial evaluates effects of copper deficiency on colonic health, indicating significant implications for dietary nutrition.

This study investigates how a lack of copper in the diet affects colonic health, inflammation, and gut microbiota in mice.
Weaned mice were fed a copper-deficient diet for four weeks followed by copper sulfate treatment for one week.
Colonic health was assessed using histopathology, immunofluorescence, ELISA, Western blot, and qRT-PCR.
Gut microbiota composition was analyzed through 16S rRNA sequencing.
CuD mice showed significant mucosal thinning, inflammatory cell infiltration, and reduced goblet cells compared to controls.
Pro-inflammatory cytokines (TNF-α, IL-1β, IL-6) and NF-κB phosphorylation were elevated in CuD mice.
Gut microbiota analysis showed decreased diversity and richness, with a decline in beneficial bacteria and an increase in pro-inflammatory taxa.

Hu et al. (2026) studied this question.
