What is the effect of dietary potassium on blood pressure?
Several studies have shown that increasing dietary potassium intake can lower blood pressure. A meta-analysis conducted by Whelton et al. in 1997 found that increasing dietary potassium intake was associated with a reduction in systolic and diastolic blood pressure. Furthermore, a study conducted by Morris et al. in 1999 found that increasing dietary potassium intake was associated with a reduction in systolic blood pressure among individuals who were salt sensitive. These findings are supported by the Institute of Medicine, which recommends that adults consume 4.7 grams of potassium daily for optimal health.
