Indigenous people of northern Canada traditionally lived a nomadic lifestyle subsisting on wild game and fish for thousands of years.
With colonization came an increasing dependence on imported processed foods.
This dietary change has often been reported to be one of the factors leading to Indigenous health and wellbeing disparities worldwide.
We determined the amino acid (AA) profile including tryptophan (Trp) of wild meats (game and fish) and processed meats found in the traditional and modern diets of Indigenous subarctic communities in Canada.
Trp is a limited essential AA necessary for synthesis of serotonin (5-HT), an important neurotransmitter and homeostatic regulator.
The dietary ratio of Trp relative to other large neutral AAs (LNAA) can alter Trp transport and 5-HT synthesis in the brain.
We determined AA composition of wild meats and processed meats using standardized NaOH and HCl hydrolysis for Trp and other AAs, respectively, followed by ultraperformance liquid chromatography.
A Principal Components Analysis revealed that overall AA composition is significantly different between wild and processed meats.
(M)ANOVA showed significantly higher protein in wild meats (wet weight, ww).
Trp was significantly lower in processed meat samples (n=15; 0.18g/100g ± 0.02 ww) compared to wild meat samples (n=25; 0.24g/100g ± 0.06 ww).
The proportion of Trp:LNAA and Trp in sample protein were not significantly different between wild (1:21-1:27, 0.92-1.27 g/100g protein) and processed (1:20-1:24, 1.03-1.27 g/100g protein) meats.
Within wild meats, AA composition is significantly different between fish and waterfowl, fish and moose, and moose and goose.
(M)ANOVA results indicate significantly higher protein in goose compared to moose and fish and in moose compared to fish.
We compared our Trp findings to previous analyses and discuss the substantial gap in human nutritional studies of Trp.
