    Published in PLoS ONE

    Methodology

    4-week controlled feeding crossover study with high- vs low-temperature cooked meat and putative mutagen inhibitors; comet assay on rectal biopsies and lymphocytes

    Key Findings

    High-temperature meat increased colon and lymphocyte DNA damage; chlorophyllin tablets alongside cruciferous vegetables and yogurt reduced this damage.

    Conclusions

    Chlorophyllin can attenuate diet-derived genotoxic exposure at the colorectal mucosa.

    Limitations

    Very small sample; chlorophyllin tested within a combined intervention, so its independent contribution is uncertain; surrogate DNA-damage endpoints.

    Supplements Studied

    Chlorophyll
    Compound

    We enrolled 16 healthy volunteers in a 4-week controlled feeding study... in combination with 3 putative mutagen inhibitors: cruciferous vegetables, yogurt, and chlorophyllin tablets.
