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 chlorine ions. Salt is involved in regulating the water content (fluid balance) of the body. Both sodium and chlorine ions are used for electrical signaling ...
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 ...
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.
Hyponatremia occurs 1) when the hypothalamic-kidney feedback loop is overwhelmed by increased fluid intake, 2) the feedback loop malfunctions such that ADH is always "turned on", 3) the receptors in the kidney are always "open" regardless of there being no signal from ADH to be open; or 4) there is an increased ADH even though there is no ...
[14] [3] If a person has low total body water and low sodium they are typically given fluids. [3] If a person has high total body water (such as due to heart failure or kidney disease) they may be placed on fluid restriction, salt restriction, and treated with a diuretic. [3]
A bit of salt in the diet is necessary for good health. The seasoning is also a kitchen staple and taste booster, but Americans consume way too much — usually without even picking up a saltshaker.
Low-Sodium Soy Sauce. While soy sauce is salty, it also adds a deeper umami flavor that many dishes practically beg for. But be sure to look for low-sodium soy sauce.
The body (in particular the brain) adapts to the higher sodium concentration. Rapidly lowering the sodium concentration with free water, once this adaptation has occurred, causes water to flow into brain cells and causes them to swell. This can lead to cerebral edema, potentially resulting in seizures, permanent brain damage, or death.
