A Mayo Clinic Arizona study found racial disparities in anemia and nutrient deficiencies in the US. American Indians/Alaskan natives and African Americans showed higher anemia rates, with the former also having significant serum folate and iron deficiencies, and Asians having the highest vitamin B12 deficiency. The disparities likely arise from diverse medical, nutritional, and social factors, underscoring the need for more research and targeted nutritional interventions in at-risk racial groups to combat healthcare inequalities in nutritional anemias.
