Carboxymethylcellulose (CMC) alters the gut microbiota

Universal food additive Carboxymethylcellulose (CMC) alters the gut microbiota

  • Carboxymethylcellulose (CMC) is a synthetic compound widely used as a food additive or emulsifier which enhances texture and promotes shelf life of processed foods since the 1960s however CMC has never been extensively tested in humans.
  • Researchers performed a randomized controlled-feeding study in healthy volunteers:
    1. The controlled group consumed an additive-free diet.
    2. The experimental group consumed an identical diet supplemented with CMC.
  • They found that:
    1. CMC consumption selectively reduced bacterial species leading in the gut microbiota.
    2. Fecal samples the experimental group displayed a drastic depletion of beneficial metabolites important to maintain a healthy colon.
    3. Colonoscopies experimental group displayed gut bacteria encroaching into the mucus similar to the inflammatory bowel diseases and type 2 diabetes cases.
  • These results suggest that further approaches & researches are needed to predict the effect of other food additives on humans.
