An insufficient amount of research has focused on the relationship between dietary intake and type 2 diabetes among African Americans (AA) which are disproportionately affected by the disease. This study examined the association of dietary fiber intake on metabolic risk factors for type 2 diabetes in AA men with a family history of type 2 diabetes. Measurements of anthropometry, blood pressure, DXA, and blood lipid profiles from the ARTIIS study (parent study) were used in the current study. Also, food frequency questionnaire and lifestyle history questionnaire were used. Outcomes indicated that dietary fiber intake is far below recommendations in AA men. Subjects that consumed higher dietary fiber had lower LDL-C (P≤0.05) and they self-reported currently exercising (P≤0.05). The relationship between dietary fiber and metabolic risk factors for type 2 diabetes was not evident. Our findings indicate the imperative need to further examine dietary patterns within AA and their influence on metabolic outcomes.
