Dietary calcium in human hypertension
Science (New York, N.Y.)
|July 16, 1982
Summary
This pilot study found that individuals with essential hypertension consumed significantly less dietary calcium daily compared to normotensive controls. Lower calcium intake, particularly from dairy, may contribute to hypertension development.
Area of Science:
- Nutrition Science
- Cardiovascular Health
- Epidemiology
Background:
- Essential hypertension is a prevalent cardiovascular condition.
- Dietary factors are increasingly recognized for their role in blood pressure regulation.
- Calcium's role in blood pressure is under investigation.
Purpose of the Study:
- To investigate the dietary calcium intake differences between normotensive and hypertensive individuals.
- To explore potential links between calcium consumption and essential hypertension.
Main Methods:
- A pilot survey was conducted comparing dietary calcium intake.
- Participants included 46 subjects with essential hypertension and 44 normotensive controls.
- Nutrient intake, including calcium, sodium, and potassium, was assessed.
Main Results:
- Hypertensive subjects ingested significantly less daily calcium (668 mg) than normotensive controls (886 mg).
- Sodium and potassium intake were similar between groups.
- Differences in calcium intake were mainly associated with non-fluid dairy product consumption.
Conclusions:
- Inadequate dietary calcium intake may be a novel factor in the development of essential hypertension.
- Further research is warranted to confirm the association between low calcium intake and hypertension.
- Dietary dairy consumption patterns may influence hypertension risk.
