While the original study was designed to test the effects of several varying nutrients on blood pressure, DASH-Sodium varies only in salt content in the diet. [12] Participants were pre-hypertensive or at stage 1 hypertension and either ate a DASH Diet or a diet reflecting an "average American Diet".
A 2020 Cochrane systematic review [75] concludes that for white people with hypertension, reducing salt intake results in a decrease of about 4 mmHg (about 3.5%) of their blood pressure; for people with normal blood pressure, the decrease was negligible. Weak evidence indicated that these effects might be a little greater in black and Asian people.
For certain people with salt-sensitive blood pressure or diseases such as Ménière's disease, this extra intake may cause a negative effect on health. WHO guidelines [ 4 ] [ 5 ] state that adults should consume less than 2,000 mg of sodium/day (i.e. about 5 grams of traditional table salt), and at least 3,510 mg of potassium per day. [ 6 ]
But the blood pressure benefits of this breakfast don’t stop there. Smoked salmon provides a healthy dose of omega-3 fats, another key nutrient for lower blood pressure. This bowl also boasts 15 ...
A low sodium diet has a useful effect to reduce blood pressure, both in people with hypertension and in people with normal blood pressure. [7] Taken together, a low salt diet (median of approximately 4.4 g/day – approx 1800 mg sodium) in hypertensive people resulted in a decrease in systolic blood pressure by 4.2 mmHg, and in diastolic blood pressure by 2.1 mmHg.
The levels of increased mortality among those with restricted salt intake appeared to be similar regardless of blood pressure. This evidence shows that while those with hypertension should primarily focus on reducing sodium to recommended levels, all groups should seek to maintain a healthy level of sodium intake of between 4 and 5 grams ...
In a systematic review, the DASH diet reduced blood pressure by an average of 5.2/2.6 mmHg, however the blood pressure lowering effects may vary and will typically have a greater effect in people with a higher baseline blood pressure (especially those with hypertension) or BMI. [22]
Hyponatremia or hyponatraemia is a low concentration of sodium in the blood. [4] It is generally defined as a sodium concentration of less than 135 mmol/L (135 mEq/L), with severe hyponatremia being below 120 mEq/L. [3] [8] Symptoms can be absent, mild or severe.
