Dietary calcium in human hypertension

Findings are presented from a pilot nutrition survey that compared calcium (Ca) intake in 46 humans with established hypertension (HTN) with that of 44 normal subjects (group-matched for age, sex, and race). These data were compared with nutritional data from the Health and Nutrition Examination Sur...

Description
Summary:Findings are presented from a pilot nutrition survey that compared calcium (Ca) intake in 46 humans with established hypertension (HTN) with that of 44 normal subjects (group-matched for age, sex, and race). These data were compared with nutritional data from the Health and Nutrition Examination Survey (HANES). Significantly less mean Ca ingestion/day was observed for the HTN group relative to the normal control group (668 versus 886 milligrams Ca/day, respectively). In contrast, the intakes of other nutrients (calories, fat, protein, sodium, and potassium) were similar between the 2 groups. The HTN group differed from the control group mostly in consumption of non-fluid dairy products. The results indicate that lower and inadequate Ca intake may be a previously unrecognized risk factor in hypertension incidence. The study was not designed to include possible socioeconomic influences. (wz)
