Key result
Less favorable diets have an unclear influence on higher blood pressure risk in Black Americans.
Why the study?
Do dietary factors explain the higher prevalence of adverse blood pressure and hypertension in US blacks compared to whites?
Do dietary factors explain the higher prevalence of adverse blood pressure and hypertension in US blacks compared to whites?
While US blacks have higher rates of hypertension and less favorable dietary intakes compared to whites, the specific impact of dietary factors on this disparity remains unclear.
Dietary disparities' role in racial hypertension gaps remains unclear; leaves open targeted prospective mediation studies.
Adverse blood pressure (BP) is a major independent risk factor for epidemic cardiovascular diseases affecting almost one third of the US adult population. This review synthesizes results from studies published over the past few years on BP differences and prevalent hypertension between US blacks and whites and their different intakes of foods (e.g., fruits, vegetables, and dairy products) and micronutrients (e.g., vitamin D, calcium, potassium, and phosphorus). Studies have consistently reported higher prevalence of adverse BP levels and hypertension and less favorable dietary intakes in blacks than in whites, but the influence of specific dietary factors on high BP risk for blacks remains unclear.

Chan et al. (2015) conducted a review in Adverse blood pressure and hypertension. Dietary factors was evaluated on Blood pressure differences and prevalent hypertension. Dietary factors such as intakes of fruits, vegetables, dairy, and micronutrients are less favorable in US blacks than whites, but their specific influence on higher blood pressure risk remains unclear.
