What is the relationship between calcium intake and blood pressure in healthy and hypertensive adults?
-
Conclusion
The findings from ten studies do not support a strong relationship between increasing calcium intake and lowered blood pressure in healthy and hypertensive adults.
-
Grade: II
- Grade I means there is Good/Strong evidence supporting the statement;
- Grade II is Fair;
- Grade III is Limited/Weak;
- Grade IV is Expert Opinion Only;
- Grade V is Not Assignable.
- High (A) means we are very confident that the true effect lies close to that of the estimate of the effect;
- Moderate (B) means we are moderately confident in the effect estimate;
- Low (C) means our confidence in the effect estimate is limited;
- Very Low (D) means we have very little confidence in the effect estimate.
- Ungraded means a grade is not assignable.

What is the relationship between potassium intake and blood pressure in healthy and hypertensive adults?-
Conclusion
Fifteen studies support a modest relationship between increasing intake of potassium and a lower sodium-potassium ratio with lowered blood pressure in healthy and hypertensive adults.

What is the relationship between sodium intake and blood pressure in healthy and hypertensive adults?-
Conclusion
Seventeen studies demonstrate the benefit of reducing dietary sodium intake for lowering blood pressure. A sodium intake of less than 2,300mg per day and further reduction of sodium intake to 1,600mg may have additional blood pressure-lowering effects, especially when combined with the DASH dietary pattern.
