Blacks in the United States have higher blood pressures than whites. They ingest and excrete less calcium and potassium. There is some evidence that blacks have a difference in vitamin D metabolism that might increase any problem caused by low calcium intake. Some studies can be interpreted to suggest that calcium or potassium therapy has greater hypotensive effects in blacks than in whites. Decreased intake of calcium and potassium may be major causes of the greater prevalence of hypertension in blacks than in whites.
美国黑人的血压高于白人。他们摄入和排出的钙和钾较少。有证据表明，黑人在维生素D代谢方面存在差异，这可能会加重因钙摄入量低而引发的任何问题。一些研究可以解释为，钙或钾疗法对黑人的降压效果比对白人的更大。钙和钾摄入量的减少可能是黑人高血压患病率高于白人的主要原因。
