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

Primary prevention of hypertension by nutritional-hygienic means. Final report of a randomized, controlled trial.
A 5-year trial involving 201 men and women with high-normal blood pressure at baseline demonstrated the ability to reduce the incidence of hypertension in participants r and omized to nutritional-hygienic intervention compared with a control group . The incidence of hypertension was 8.8 % among 102 intervention group participants vs 19.2 % among 99 control group members . The odds ratio for the incidence of hypertension in the control group was 2.4 . Mean trial blood pressure also was lower in the intervention compared with the control group ( -1.2 and -1.9 mm Hg , respectively , for diastolic blood pressure at work-site and office visits and -1.3 and -2.0 mm Hg , respectively , for systolic blood pressure at the two sites ) . Net weight loss in the intervention group averaged 2.7 kg during the trial ; sodium intake was reduced by 25 % and reported alcohol intake decreased by 30 % . The majority of intervention participants also reported an increase in physical activity . Effect on blood pressure was related particularly to degree of weight loss . Results indicate that even a moderate reduction in risk factors for hypertension among hypertension-prone individuals contributes to the primary prevention of the disease
