EFFECT OF SOLUBLE AND INSOLUBLE FIBER DIETS ON SERUM PROSTATE SPECIFIC ANTIGEN IN MEN

Abstract
Conclusions: A small but statistically significantly lower serum PSA was seen in healthy men consuming soluble fiber, which was not related to changes in serum sex hormones but was related to the increased lithocholic acid output as a possible marker of increased fecal steroid elimination. The effect of soluble fiber on prostatic disease may warrant further investigation.
