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 poisoning sufficient to produce severe symptoms is rare, and lethal salt poisoning is possible but even rarer. The lethal dose of table salt is roughly 0.5–1 gram per kilogram of body weight. [1] In medicine, salt poisoning is most frequently encountered in children or infants [2] [3] who may be made to consume excessive amounts of table ...
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.
Recent research indicates that using potassium-enriched salt substitutes instead of regular salt may lead to a 14% reduction in recurrent stroke rates and a 21% decrease in deaths related to strokes.
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.
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 intracellular fluids, and resting membrane potential.
Vitamin D deficiency was the most common deficiency, with a prevalence of over 60% among people with type 2 diabetes Magnesium ranked second as the most common deficiency, with about 42% of people ...
The human minimum requirement for sodium in the diet is about 500 mg per day, [3] which is typically less than one-sixth as much as many diets "seasoned to taste". 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.
