SEM image of a grain of table salt. The health effects of salt are the conditions associated with the consumption of either too much or too little salt. Salt is a mineral composed primarily of sodium chloride (NaCl) and is used in food for both preservation and flavor. Sodium ions are needed in small quantities by most living things, as are ...
Salt fulfills several important biological functions in humans. The human body has evolved to compensate for high salt intake through regulatory systems such as the renin–angiotensin system . Salt is particularly involved with maintaining body fluid volume, including the regulation of osmotic balance in the blood, extracellular and ...
Pink Himalayan salt has also become a consumer favorite because of its purported health benefits – it gets its hue from added minerals like calcium, magnesium, potassium and iron.
Most of the chloride in the body is from salt (NaCl) in the diet. [19] Chloride is part of gastric acid (HCl), which plays a role in absorption of electrolytes, activating enzymes, and killing bacteria. The levels of chloride in the blood can help determine if there are underlying metabolic disorders. [20]
Saline is in the crystalloid family of medications. [3] It is most commonly used as a sterile 9 g of salt per litre (0.9%) solution, known as normal saline. [1] Higher and lower concentrations may also occasionally be used. [4] [5] Saline is acidic, with a pH of 5.5 (due mainly to dissolved carbon dioxide). [6] The medical use of saline began ...
At the end of the third year, 54% of women had been treated with cholesterol-lowering medications compared with 74% of men. Five percent of women were treated with statins compared to 8% of men.
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.
Potassium closely resembles the saltiness of sodium. In practice, potassium chloride (also known as potassium salt) is the most commonly used salt substitute. Its toxicity for a healthy person is approximately equal to that of table salt (the LD 50 is about 2.5 g/kg, or approximately 190 g for a person weighing 75 kg).
