A pilot survey was made of the dietary calcium intake normotensive and hypertensive individuals. Compared to 44 controls, 46 subjects with essential hypertension reported significantly less daily ingestion (668 ± 55 milligrams compared 886 89 milligrams). The other nutrients, including sodium potassium, very similar in two groups. hypertensives differed from controls primarily their consumption nonfluid dairy products. data suggest that inadequate may be a previously unrecognized factor...
