Meer dan 2 gram EPA en DHA per dag verlaagt de bloeddruk

Research Question:
The intake of EPA and DHA lowers blood pressure?

Study Design:
This overview article contained 70 RCTs. The average study duration was 69 days and the average intake of EPA and DHA was 3.8 grams per day.

Results and conclusions:
The researchers found that the intake of EPA and DHA (through diet and supplements) the systolic blood pressure (systolic blood pressure) significantly with 1.52 mmHg [95% CI =-2.25 to-0.79] reduced.

The researchers found that the intake of EPA and DHA (through diet and supplements) the diastolic blood pressure (underpressure) significantly with 0.99 mmHg [95% CI =-1.54 to-0.44] reduced.

The researchers found that the intake of EPA and DHA systolic blood pressure among people with high blood pressure significantly with 4.51 mmHg [95% CI =-6.12 to-2.83] reduced.

The researchers found that the intake of EPA and DHA the diastolic blood pressure among people with high blood pressure significantly with 3.05 mmHg [95% CI =-4.35 to-1.74] reduced.

The researchers found that the intake of EPA and DHA systolic blood pressure among people with normal blood pressure significantly with 1.25 mmHg [95% CI =-2.05 to-0.46] reduced.

The researchers found that the intake of EPA and DHA the diastolic blood pressure among people with normal blood pressure significantly with 0.62 mmHg [95% CI =-1.22 to-0.02] reduced.

The researchers found that swallowing of EPA and DHA supplements the systolic blood pressure significantly with 1.75 mmHg [95% CI =-2.55 to-0.94] and the diastolic blood pressure significantly with 1.11 mmHg [05% CI =-1.72 to-0.50] reduced.

The researchers found that the intake of EPA and DHA (through diet and supplements) to 2 grams per day systolic blood pressure significantly with 1.81 mmHg [95% CI =-3.59 to-0.03] and 3-4 grams per day with 3.85 mmHg [95% CI =-5.55 to-2.15] reduced.

The researchers found that the intake of EPA and DHA (through diet and supplements) to 2 grams per day the diastolic blood pressure non-significant reduced. However, 2 to 3 grams per day reduced the diastolic blood pressure significantly with 1.09 mmHg [95% CI =-2.08 to-0.11 and 3 to 4 grams per day with 1.86 mmHg [95% CI =-2.67 to-1.06].

The researchers concluded that the intake of more than 2 grams of EPA and DHA (through diet and supplements) per day reduced both systolic and diastolic blood pressure, particularly among people with high blood pressure that no blood pressure lowering medications.
