Salt is particularly involved with maintaining body fluid volume, including the regulation of osmotic balance in the blood, extracellular and intracellular fluids, and resting membrane potential. [8] The well-known effect of sodium on blood pressure can be explained by comparing blood to a solution with its salinity changed by ingested salt.
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.
“The present study extended the effect of salt substitutes to people with normal blood pressure,” Wu said. Systolic — the top number in a blood pressure reading — indicates the amount of ...
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 ...
Although there are clear benefits of using salt substitutes for many with high blood pressure, more research needs to be done about its effects on those with normal or healthy blood pressure as a ...
A salt substitute. A salt substitute, also known as low-sodium salt, is a low-sodium alternative to edible salt (table salt) marketed to reduce the risk of high blood pressure and cardiovascular disease associated with a high intake of sodium chloride [1] while maintaining a similar taste.
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.
That means eating salt doesn't hugely affect his blood pressure. Instead, he ate more potassium, which the World Health Organization recommends to reduce high blood pressure, by using a salt ...
