In this review the up-to-date literature data about exorphins are analysed. Exorphins are short opioid-like food-derived peptides. Different reports about their physiological impact in animals and humans are reviewed with focus on neurotropic effects. Clinical data (case reports and clinical trials' results), on the one hand, and the results of experiments with animals of different taxons, on the other hand, are summarized. The influence of exorphins on infants' development is emphasized.

Beyond the gut: Investigating the mechanism of formation of β-casomorphins in human blood.

To evaluate the potential differences in the propensity of β-casein A1 (β-CNA1) and A2 (β-CNA2) from bovine milk to release health-relevant β-casomorphins (BCMs), food-derived peptides were monitored over time in the blood of eight human volunteers who consumed milk containing both protein variants. Liquid chromatography coupled with high resolution tandem mass spectrometry revealed interindividual variability of milk peptidomic profiles in human blood. BCMs were not detected, whereas BCM precursors originating from both β-CNA1 and β-CNA2 were ascertained, with β-CNA2-derived peptides showing a slightly greater susceptibility to proteolysis.

Bovine milk peptides are the protein fragments with diverse bioactive properties having antioxidant, anticarcinogenic, other therapeutic and nutraceutical potentials. These peptides are formed in milk by enzymatic hydrolysis, gastrointestinal digestion and fermentation processes. They have significant health impact with high potency and low toxicity making them a suitable natural alternative for preventing and managing diseases.

Bioactive peptides are found in foods and dietary supplements and are responsible for health benefits with applications in human and animal medicine. The health benefits include antihypertensive, antimicrobial, antithrombotic, immunomodulatory, opioid, antioxidant, anti-allergic and anti-inflammatory functions. Bioactive peptides can be obtained by microbial action, mainly by the gastrointestinal microbiota from proteins present in food, originating from either vegetable or animal matter or by the action of different gastrointestinal proteases.

Rubiscolin‑6 is a food‑derived opioid peptide found in that has anti‑nociceptive, memory‑enhancing, anxiolytic‑like and anti‑depressant effects. Rubiscolin‑6 has been reported to have two opposing effects on food intake. Food intake is closely connected to gut motility; however, to the best of our knowledge, the effect of rubiscolin‑6 on gut motility has not been reported.

Food-derived opioid peptides include digestive products derived from cereal and dairy diets. If these opioid peptides breach the intestinal barrier, typically linked to permeability and constrained biosynthesis of dipeptidyl peptidase-4 (DPP4), they can attach to opioid receptors. The widespread presence of opioid receptors spanning gut, brain, and internal organs is fundamental to the diverse and systemic effects of food-derived opioids, with effects being evidential across many health conditions.
