Abstract

Insights

A novel natural fiber-rich food product (NFRFP) demonstrated safety and chemopreventive effects against colorectal cancer in a rat model. This fiber-rich product significantly reduced DNA damage and aberrant crypt foci, suggesting dietary applicability.

Area of Science:

  • Nutritional Science
  • Gastroenterology
  • Toxicology

Background:

  • Colorectal cancer (CRC) is a prevalent malignancy necessitating effective prevention and treatment strategies.
  • Developing novel dietary interventions is crucial for managing CRC risk.
  • Natural fiber-rich food products (NFRFP) offer a promising avenue for chemoprevention.

Purpose of the Study:

  • To formulate a natural fiber-rich food product (NFRFP).
  • To evaluate the safety, toxicogenetics, and chemopreventive efficacy of NFRFP against 1,2-dimethylhydrazine-induced aberrant crypt foci in a preclinical model.

Main Methods:

  • Seventy-eight male Wistar rats were divided into six groups: control and 1,2-dimethylhydrazine (DMH) treated.
  • DMH-treated groups received NFRFP via pre-treatment, simultaneous, or post-treatment protocols.
  • Safety assessments included biometric, biochemical, hematological, and genotoxicity evaluations.

Main Results:

  • NFRFP proved to be a good fiber source, exhibiting no adverse effects on biometric, biochemical, hematological, or inflammatory parameters.
  • NFRFP demonstrated significant chemopreventive effects, achieving 75% damage reduction in the comet assay.
  • The NFRFP reduced aberrant crypt foci incidence by 49.36% in the post-treatment protocol.

Conclusions:

  • The NFRFP is safe and non-toxic, showing no genotoxic or carcinogenic potential.
  • NFRFP exhibits significant chemopreventive properties against chemically induced colorectal aberrant crypt foci.
  • The study supports the potential industrial-scale application of NFRFP in human diets due to its safety and minimal impact on sensory characteristics.
