Abstract

Food protein-derived bioactive peptides are recognized as valuable ingredients of functional foods and/or nutraceuticals to promote health and reduce the risk of chronic diseases. However, although peptides have been demonstrated to exert multiple benefits by biochemical assays, cell culture, and animal models, the ability to translate the new findings into practical or commercial uses remains delayed. This fact is mainly due to the lack of correlation of in vitro findings with in vivo functions of peptides because of their low bioavailability. Once ingested, peptides need to resist the action of digestive enzymes during their transit through the gastrointestinal tract and cross the intestinal epithelial barrier to reach the target organs in an intact and active form to exert their health-promoting properties. Thus, for a better understanding of the in vivo physiological effects of food bioactive peptides, extensive research studies on their gastrointestinal stability and transport are needed. This review summarizes the most current evidence on those factors affecting the digestive and absorptive processes of food bioactive peptides, the recently designed models mimicking the gastrointestinal environment, as well as the novel strategies developed and currently applied to enhance the absorption and bioavailability of peptides.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Many algal peptides have demonstrated promising biological activity in vitro, but their behavior within the human digestive system is not fully understood.

    “Although many peptides have demonstrated promising biological activity in vitro, their behavior within the human digestive system is not fully understood [202].”

    From Navigating the potential of algal peptides: health effects, market applications, and scientific challenges (2026) · cites this paper as [202]

    The Introduction and Conclusions support the printed sentence’s general point: food peptides show in vitro bioactivity, but their digestion and bioavailability in vivo remain incompletely understood. The claim adds an algal-peptide qualifier that these passages do not establish. (LLM, conf=0.85)

  • The field lacks a substantial body of clinical data; most current evidence is derived from in vitro assays or animal models, which do not necessarily translate to human outcomes.

    “Moreover, the field still lacks a substantial body of clinical data. Most of the current evidence is derived from in vitro assays or animal models, which, although informative, do not necessarily translate to human outcomes [202].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
