Ballast matter, or dietary fiber, includes indigestible food components and incompletely digested nutrients. Research suggests expanding this definition to include "optional" ballast matter, which impacts gut microbes.

Area of Science:

  • Microbiology
  • Nutrition Science
  • Gastroenterology

Context:

  • Dietary components traditionally defined as ballast matter (dietary fiber) are resistant to host digestive enzymes.
  • Gut microbes in the hind-gut metabolize these undigestible substances.
  • Digestible nutrients escaping small intestine digestion also function similarly to ballast matter.

Purpose:

  • To propose an expanded definition of ballast matter encompassing both "obligatory" (indigestible) and "optional" (incompletely digested) components.
  • To investigate the microecological-physiological effects of "optional" ballast matter.
  • To provide evidence for the role of "optional" ballast matter in gut health.

Summary:

  • The traditional definition of ballast matter (dietary fiber) includes only nutrients indigestible by host enzymes.

  • This study introduces "optional" ballast matter: usually digestible nutrients incompletely degraded in the small intestine.
  • Microecological-physiological experiments with rats demonstrated the effects of lactose, an "optional" ballast matter, on gut microbiota.

    • Impact:

    • Suggests a broader understanding of dietary fiber's role in the gut microbiome.
    • Highlights the significance of incompletely digested nutrients for microbial metabolism.
    • Provides a foundation for further research into "optional" ballast matter and its health implications.
