2.3-3.1 gram kalium per dag verlaagt de bloeddruk

Research Question:
Eating potassium lowers blood pressure?

Study Design:
This overview article contained 22 Rcts with 1606 participants and 11 cohort studies with 127038 participants.

Results and conclusions:
The researchers found that an increased potassium intake through feeding the systolic blood pressure significantly with 3.49 mmHg [95% CI = 1.82-5.15] and vacuum significantly with 1.96 mmHg [95% CI = 0.86-3.06] in people with high blood pressure, lowered. This reduced effect was not found in people with normal blood pressure.

The researchers found that a potassium intake of 90-120 mmol per day the systolic blood pressure significantly with 7.16 mmHg [95% CI = 1.91-12.41] reduced. Significant is, there is a link at a 95% reliability. The reduced effect was not dose-dependent and the reduced effect took over 120 mmol per day not matter anymore.

The researchers found that an increased potassium intake via diet had no significant negative effect on the kidney function, the blood fats or catecholamineconcentratie in adults.

The researchers found that an increased potassium intake the likelihood of getting a stroke significantly with 24% [95% CI = 0.66-0.89] reduced.

The researchers found that an increased potassium intake chances of getting heart disease non-significant 4% [95% CI = 0.78-1.19] reduced. Non-significant is, there is no link to a 95% reliability, but a trend.

The researchers concluded that eating 90-120 mmol (2.3-3.1 grams) potassium per day lowered blood pressure.
