Abstract

Objectives: This systematic review synthesizes extant literature that examines relationships between nutrition and brain health in Indigenous populations in North America and further assesses the extent to which Indigenous research paradigms and community engagement processes have been employed.

Methods: We searched five databases for primary research studies that examined indices of diet/nutrients in relation to brain health and focused on Indigenous populations in North America. Quality appraisal was performed using the Aboriginal and Torres Strait Islander Quality Appraisal Tool as well as the Appraisal Tool for Cross-Sectional Studies, the JBI Critical Appraisal Checklist for Case Control Studies, or the Critical Appraisal Skills Programme Cohort Study Checklist.

Synthesis: Of the 564 articles identified in the search, 16 met inclusion criteria. Ten studies focused on Inuit populations, 2 focused on the residents of Grassy Narrows First Nation, 2 focused on Cree populations, and 2 focused on Quileute, Makah, and Quinault First Nations populations. Fourteen studies reported deleterious effects of dietary contaminants (e.g., mercury, lead, polychlorinated biphenyls) on brain health outcomes and three studies reported beneficial effects of omega-3 polyunsaturated fatty acids on brain health outcomes.

Conclusion: Findings of this review highlight the neurotoxic effects of environmental contaminants and the beneficial effects of omega-3 polyunsaturated fatty acids in traditional Indigenous food sources on a range of brain health outcomes. However, given the methodological limitations of the studies reviewed and the lack of community-based research that employs Indigenous research paradigms, results should be interpreted with caution. There is a clear need for strength-based research that examines the positive effects of nutrients within traditional Indigenous foods on brain health.

探索北美土著居民营养与大脑健康之间的关系:一项系统综述。
目的:本系统综述综合了现有文献,研究了北美土著人口营养与大脑健康之间的关系,并进一步评估了土著研究范式和社区参与过程的应用程度。方法:我们检索了五个数据库,检索了与大脑健康相关的饮食/营养指标的初步研究,并重点关注了北美的土著人口。质量评估使用土著和托雷斯海峡岛民质量评估工具以及横断面研究评估工具、JBI病例对照研究关键评估清单或关键评估技能项目队列研究清单进行。综合:在检索到的564篇文章中,有16篇符合纳入标准。10项研究集中在因纽特人身上,2项研究集中在Grassy Narrows第一民族的居民身上,2项研究集中在克里人身上,2项研究集中在Quileute、Makah和Quinault第一民族身上。14项研究报告了饮食污染物(如汞、铅、多氯联苯)对脑健康结果的有害影响,3项研究报告了omega-3多不饱和脂肪酸对脑健康结果的有益影响。结论:本综述的发现强调了环境污染物的神经毒性作用和传统土著食物来源中omega-3多不饱和脂肪酸对一系列脑健康结果的有益作用。然而,鉴于所审查的研究在方法上的局限性,以及缺乏采用土著研究范式的以社区为基础的研究,对结果的解释应谨慎。显然有必要进行以力量为基础的研究,以检验传统土著食物中的营养物质对大脑健康的积极影响。
