Robust statistically significant effects were found for improved diet , aerobic exercise , alcohol and sodium restriction , and fish oil supplements : mean reductions in systolic blood pressure of 5.0 mmHg [ 95 % confidence interval ( CI ) : 3.1 - 7.0 ] , 4.6 mmHg ( 95 % CI : 2.0 - 7.1 ) , 3.8 mmHg ( 95 % CI : 1.4 - 6.1 ) , 3.6 mmHg ( 95 % CI : 2.5 - 4.6 ) and 2.3 mmHg ( 95 % CI : 0.2 - 4.3 ) , respectively , with corresponding reductions in diastolic blood pressure .
Relaxation significantly reduced blood pressure only when compared with non-intervention controls .
We found no robust evidence of any important effect on blood pressure of potassium , magnesium or calcium supplements .
Available evidence does not support relaxation therapies , calcium , magnesium or potassium supplements to reduce blood pressure
PURPOSE To quantify effectiveness of lifestyle interventions for hypertension .
Reduction in blood pressure with a low sodium, high potassium, high magnesium salt in older subjects with mild to moderate hypertension
Abstract Objective : To examine the effect of a reduced sodium and increased potassium and magnesium intake on blood pressure . Design : R and omised double blind placebo controlled trial . Setting : General population of a suburb of Rotterdam . Subjects : 100 men and women between 55 and 75 years of age with untreated mild to moderate hypertension . Interventions : During 24 weeks the intervention group received a mineral salt ( sodium : potassium : magnesium 8:6:1 ) and foods prepared with the mineral salt . Controls received common salt and foods . Main outcome measure : Change in blood pressure . Results - Complete follow up was achieved for 97 of the 100 r and omised subjects .  Systolic blood pressure ( mean of measurements at weeks 8 , 16 , and 24 ) fell by 7.6 mm Hg ( 95 % confidence interval 4.0 to 11.2 ) and diastolic blood pressure by 3.3 mm Hg ( 0.8 to 5.8 ) in the mineral salt group compared with the controls , with a 28 % decrease in urinary sodium excretion and a 22 % increase in urinary potassium excretion . Twenty five weeks after the study the difference in blood pressure between the groups was no longer detectable . Conclusion : Replacing common sodium salt by a low sodium , high potassium , high magnesium mineral salt could offer a valuable non -pharmacological approach to lowering blood pressure in older people with mild to moderate hypertension
