Little-known fact: high salt intake can increase blood pressure levels. Ideally, you shouldn’t consume more than 1.5 grams of sodium per day to help keep your blood pressure in a healthy range.
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.
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.
Eating a low-salt diet cut blood pressure readings by as much as the typical hypertension medication without the potential side effects, a new study found. Cutting 1 teaspoon of salt works as well ...
The salt substitute used was 25% potassium chloride and 75% sodium chloride. A 2022 Cochrane review of 26 trials involving salt substitutes reported their use probably slightly reduces blood pressure, non-fatal stroke, non-fatal acute coronary syndrome and heart disease death in adults compared to use of regular table salt.

When we think about trying to lower high blood pressure, we usually think of limiting salt and processed foods.But, a heart-healthy diet is more than just lowering your sodium intake. The DASH ...
Why Does Salt Raise Blood Pressure? While salt, or sodium chloride, plays a crucial role in regulating the body's fluid balance, excess sodium causes the body to retain water.
When salt is ingested, it’s dissolved in the blood as two separate ions – Na + and Cl −. The water potential in blood will decrease due to the increased solutes, and blood osmotic pressure will increase. While the kidney reacts to excrete excess sodium and chloride in the body, water retention causes blood pressure to increase. [10]
