Summary

Dietary protein intake of adequate quality is essential for human health. Traditional animal source foods play a key role in providing high quality protein but are associated with a high burden on the environment. Therefore, viable alternative protein sources are needed to be able to meet human nutritional needs for the rapidly increasing world population, while keeping food production within the planetary boundaries. T. molitor (Yellow Mealworm larvae) is a sustainably produced and commercially available edible insect, which contains a high quantity of protein with a favorable amino acid profile. Protein quality evaluation considers the amino acid composition as well as the ileal digestibility of the food's individual amino acids, to assess if human dietary requirements for essential amino acids can be met by the protein source. The present study will measure the digestibility of essential amino acids from T. molitor with a minimally invasive dual stable isotope tracer method that follows a plateau-fed test meal protocol. T. molitor will be intrinsically labelled with the stable isotope deuterium (2H), which will be given along with a reference amino acid mixture of known digestibility, labelled with the stable isotope carbon-13 (13C). Based on the results from the present study, protein quality of T. molitor as a protein source for human nutrition can be assessed, allowing a direct comparison of this novel protein source to other protein sources, such as meat and legumes.

Interventions

Type	Name	Description
OTHER	2H intrinsically-labeled T.molitor with 13-C labeled amino acid mixture	Test meal with dried 2H intrinsically labeled T.molitor and 13C labeled reference amino acid mixture will be divided into 10 portions, which will be given hourly over the course of 7 hours. The first consumption will be the priming meal, comprised of 3 portions and will additionally contain 13C sodium bicarbonate.
