SUMMARY:

Wildmeat plays a crucial role in subsistence and reducing food insecurity for a portion of the global population. However, there is a lack of knowledge regarding the micronutrient profile of this meat. In order to address this gap, we conducted a systematic review to test the hypotheses that the animal class (mammal, bird, or reptile) and its level of domestication influence the nutritional composition of the meat. For this review, we followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. We assessed studies published in the Web of Science, Scopus, and Medline/PubMed databases (via the National Library of Medicine). We developed a quality questionnaire to meticulously evaluate all included studies, and the agreement among reviewers was measured using Fleiss' Kappa. We used data imputation techniques to estimate missing values in the nutritional composition of the meats from the evaluated animals in the articles. We worked with 11 nutrients available in the studies, including proteins, lipids, omega-3, omega-6, iron, manganese, selenium, zinc, potassium, magnesium, and sodium. Descriptive statistics were used to summarize the results, and data normality was assessed using the Shapiro test. Non-parametric data analysis was conducted using the Kruskal-Wallis test and Bonferroni post hoc test. All statistical analyses were performed using the R programming language via the RStudio interface. Our review included a total of 19 articles covering 23 animal species, including 15 mammals, 7 birds, and 1 reptile. The agreement among reviewers was considered excellent (Fleiss' Kappa = 0.833), and 74% of the studies obtained a high-quality score. Our partial analyses revealed some important patterns. We found that viscera are a significant source of nutrients, similar to non-wild animal meats. Additionally, we did not observe differences in protein content among different animal classes. Surprisingly, the iron content did not vary between mammals and birds, contrary to what is observed in non-wild animal meats. Other findings include the prominence of reptiles for their selenium content, birds for potassium and lipids, and mammals for zinc and omega-3 and omega-6 fatty acids. The next steps for the research development include interpreting the results of hypothesis testing and writing the discussion section of the first dissertation product, as well as finalizing the preparation of the database for testing the second hypothesis. We plan to publish two scientific articles with the conclusions derived from this dissertation.
