Purpose of the Study:

  • To review the beneficial roles of food-derived bioactive peptides.
  • To highlight the importance of peptides generated during digestion.
  • To emphasize the need to consider latent bioactive peptides in protein quality evaluation.

Main Methods:

  • Literature review of studies on food-derived bioactive peptides.
  • Analysis of reported biological activities and sources of peptides.
  • Discussion of the implications for dietary protein quality.

Main Results:

  • Numerous bioactive peptides have been identified from various protein sources.
  • Milk-based products are a rich source of these peptides.
  • Diverse health benefits are associated with these peptides, impacting various physiological systems.

Conclusions:

  • Bioactive peptides derived from dietary proteins play a significant role in human health.
  • Their release during normal digestion is a key factor.
  • Dietary protein quality evaluation should incorporate the potential of these latent bioactive peptides.
