There is a strong correlation between higher sodium intake and higher blood pressure. [96] Studies have found that lowering sodium intake by 2 g per day tends to lower systolic blood pressure by about two to four mm Hg. [97] It has been estimated that such a decrease in sodium intake would lead to 9–17% fewer cases of hypertension. [97]
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 DASH-Sodium study found that reductions in sodium intake produced significantly lower systolic and diastolic blood pressures in both the control and DASH diets. Study results indicate that the quantity of dietary sodium in the control diet was twice as powerful in its effect on blood pressure as it was in the DASH diet.
You may need to increase your sodium intake if you are sweating a lot, such as when working out or on a hot day. “Sodium is an electrolyte needed for balanced fluid and blood volume and ...
Opting for low-sodium foods, defined as 140 mg of sodium or less per serving, can help keep your salt intake at bay. Even choosing items labeled "reduced sodium" or "no salt added" can make a ...
While reduction of sodium intake to less than 2,300 mg per day is recommended by developed countries, [9] one review recommended that sodium intake be reduced to at least 1,200 mg (contained in 3 g of salt) per day, as a further reduction in salt intake led to a greater fall in systolic blood pressure for all age groups and ethnicities. [70]
Sodium intake Salt, of course, plays a role in heart health. “For congestive heart failure, we have seen improvement by avoiding a lot of sodium in their diet,” he says.
Low sodium intake level was a mean of <115 mmol (2645 mg), usual sodium intake was 115-215 mmol (2645–4945 mg), and a high sodium intake was >215 mmol (4945 mg), concluding: "Both low sodium intakes and high sodium intakes are associated with increased mortality, consistent with a U-shaped association between sodium intake and health outcomes".
