The vitamin D paradox in Black Americans - BMC Series blog

The vitamin D paradox in Black Americans - BMC Series blog

LaVerne L. Brown

LaVerne L. Brown, Ph.D. was trained in natural products and medicinal chemistry; and she is currently a Program Officer in the Office of Dietary Supplements at the National Institutes of Health. She is developing a research portfolio that aims to clarify how metabolic adaptations to biological and environmental stressors might affect nutrient status and overall health status in individuals. Dr. Brown hopes the portfolio will promote a better understanding of biochemical mediators of resilience and increase research investigations of segments of the population that are often under-sampled in clinical studies.

The vitamin D paradox in Black Americans

According to the U.S. National Institutes of Health, a paradox exists in which, despite markedly low (or “deficient”) measures of vitamin D status in Black Americans, the incidence of falls, fractures, or osteopenia are significantly lower compared to White American counterparts with similar vitamin D status. An expert panel meeting report published in BMC Proceedings presents a panelist discussion regarding this issue.
It is generally understood that vitamin D plays a role in exerting health benefits related to bone strength and condition. However, the significance of that role is not well understood. A number of misconceptions about vitamin D may have contributed to the ambiguity and should be addressed.
