The Effects of Cricket- and Beef-derived Protein on Plasma Amino Acid Concentrations and Appetite Responses

Appetitive Behavior Clinical Trial

Official title:
The Effects of Dietary Protein Source on Postprandial Plasma Amino Acid Availability, Gut-derived Appetite Regulating Hormones, and Subjective Appetite Sensations in Young Males

Clinical Trial Summary

Dietary protein plays an important role in appetite regulation. Source of ingested dietary protein may have different effects on appetite, satiety, and/or food intake in humans. Insects are a rich source of protein consumed by many people around the world; however, the capacity of insect-derived protein to regulate appetite and food intake is unclear. The purpose of this study was to compare postprandial plasma glucose, insulin, amino acid, and appetite regulatory hormone concentrations, subjective appetite sensations, and food intake following the ingestion of 25 g of cricket- and beef-derived protein in healthy young males.

Clinical Trial Description

With the rapid increase in the global population, the production of sufficient amounts of conventional animal-based protein to meet global dietary demands may no longer be desired nor feasible. Insects may represent an environmentally sustainable additional source of dietary protein that has the potential to help ensure global food security in the future. However, the functional characteristics of insect-derived proteins when fed to humans is unclear. Further, how insect-derived proteins compare to other animal-derived proteins (e.g. from beef) have not been explored. The purpose of this study was to compare postprandial plasma glucose, insulin, and amino acid concentrations, gut-derived appetite regulatory hormones, subjective appetite sensations, and ad libitum energy intake following the ingestion of 25 g insect- or beef-derived protein in healthy young men. It was hypothesized that hyperaminoacidaemia would be more rapid following the ingestion of beef-derived protein compared to cricket-derived protein, although total amino acid availability would be similar between protein sources over a 300-minute postprandial period. It was further hypothesized there would be no difference between protein sources on postprandial subjective appetite sensations or subsequent ad libitum energy intake. ;
