Effect on Satiety-Related Biomarkers of Bar Snacks Containing Chickpea Flour and Pork Protein.

This project aims to establish the acceptability and satiety of a hybrid snack containing plant protein and a small percentage of animal protein compared to a meat-based snack.

Design: Randomised, crossover, double-blind, controlled post-prandial trial involving 24 participants (18-30 years), with two interventions: (a) a hybrid snack containing plant protein derived from chickpeas and 6.6% lean high-quality pork meat; and (b) a meat-based snack containing 90% lean pork meat.

Methods: General, life-style, sensory acceptability questionnaire, and the following laboratory analyses were performed: lipid profile, endocannabinoids, and related compounds.

Results: Sensory questionnaires showed in general good acceptability for both bars. Additionally, there was a greater increase in glycemia at 30, 60, and 90 min after consuming the hybrid snack compared to the meat-based snack, with no changes in the lipid profile. Regarding the endocannabinoid compounds and related compounds, the compound N-palmitoleoyl ethanolamine in the acylethanolamide group showed higher levels overall following the consumption of the hybrid snack compared to the meat-based snack, particularly at 2 h.

Conclusions: The hybrid snack was associated with changes in endocannabinoid-like compounds. Therefore, it may provide a lasting satiating effect, while complementing the protein profile of plant-based foods with the quality of animal protein.
