American Indian populations continue to suffer disproportionately from health problems including such nutrition-related chronic diseases as diabetes and heart disease. This research project will therefore investigate how a traditional Indigenous food called chokeberry (Aronia melanocarpa) impacts epigenetic and metabolic health in relation to resiliency markers in American Indian participants. The process of research with American Indian communities is significant in that it can inform best practices in community engagement orientations, approaches, and models in future research settings.
This study aims to explore the gene expression and metabolic changes that are mediated by consumption of Indigenous chokeberry (Aronia melanocarpa) in adult urban American Indians and to examine the associations between metabolic endpoints, adverse childhood experiences and mental health. The investigators are doing this research study to answer questions about the impact of adult urban American Indians ingesting one of their traditional Indigenous foods called chokeberry on epigenetic, metabolic and mental health markers of trauma and resilience. For this study, the investigators will be looking to determine: 1. If there are gene expression changes that are mediated by consumption of traditional Indigenous chokeberry in urban adult Great Plains Indians. 2. If there are associations between secondary outcomes such as metabolic endpoints (i.e., 8-OHdG, IL-6, lipids, glucose, CRP, blood pressure), epigenetic states, adverse childhood experiences, and mental health (historical trauma, resiliency, presence of anxiety and depression) in American Indians who have or have not consumed chokeberry as part of a controlled feeding study.

Epigenetics
The assessment of change in methylation targeted genes
Time frame: Baseline and 6 weeks
Urinary Hydroxydeoxyguanosine (8-OHdG)
A commonly used marker of oxidative stress-derived DNA assessed through urine. Assessment of the change in 8-OHdG.
Time frame: Baseline and 6 weeks
Interleukin 6 (IL-6)
Is a pro-inflammatory cytokine assessed from the blood that stimulates inflammation. Assessment of the change in IL-6 processes
Time frame: Baseline and 6 weeks
Lipid panel
Assessment of the change in HDL, LDL, total cholesterol, triglycerides levels
Time frame: Baseline and 6 weeks
C-reactive Protein (CRP)
Measure of systemic inflammation assessed from the blood. Assessment of the change in CRP.
Time frame: Baseline and 6 weeks
Blood pressure
Measure of the change in systolic blood pressure and diastolic blood pressure
Time frame: Baseline and 6 weeks
Patient Health Questionnaire-2 (PHQ-2)
Validated tool to screen for depression. Assessment of the change PHQ-2 scores. The scale runs from a minimum value of zero to a maximum value of three for each item in the questionnaire. A higher value means a worse outcome.
Time frame: Baseline and 6 weeks
2-item Generalized Anxiety Disorder Scale (GAD)
Validated tool to screen for anxiety. Assessment of the change in GAD scores. The scale runs from a minimum value of zero to a maximum value of three for each item in the questionnaire. A higher value means a worse outcome.
Time frame: Baseline and 6 weeks
Connor-Davidson Resilience Scale 2-item measure (CD-RISC2)
CD-RISC2 is a brief, self-rated measure of resilience with sound psychometric properties. Assessment of the change in CD-RISC2 scores. Assessment of the change in CD-RISC2 scores. The scale runs from a minimum value of one to a maximum value of four for each item in the questionnaire. A lower value means a worse outcome.
Time frame: Baseline and 6 weeks
Adverse Childhood Experiences (ACEs) survey (10-item version)
Collects some of the most intensive and frequently occurring sources of stress that children may suffer early in life.
Time frame: Baseline
Historical Loss Scale
This scale enumerates perceived losses and asks respondents how frequently these losses came to mind on a 12-item questionnaire specific to Indigenous Peoples. The scale runs from a minimum value of one to a maximum value of six for each item in the questionnaire. A lower value means a worse outcome and is reported in percentage frequency of perceived losses.
Time frame: Baseline
