The sodium–potassium pump, a critical enzyme for regulating sodium and potassium levels in cells. Sodium ions (Na +) are necessary in small amounts for some types of plants, [1] but sodium as a nutrient is more generally needed in larger amounts [1] by animals, due to their use of it for generation of nerve impulses and for maintenance of electrolyte balance and fluid balance.
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 ...
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.
High salt concentrations within drinking water sources can result in many harmful effects on human health. [14] A study on two coastal villages in Bangladesh showed that when freshwater contaminated with high salinity concentrations is consumed, it can result in health issues such as hair loss, skin diseases, gastric problems, diarrhea, and ...
Adults can consume too much salt by consuming seawater, pickled goods, brine water or soy sauce. [5] Salt poisoning has been seen in a number of adults with mental health problems. [6] Salt poisoning can affect most species of animals, although it is more common in swine, cattle, and poultry. [7]
If the levels of an electrolyte are too low, a common response to electrolyte imbalance may be to prescribe supplementation. However, if the electrolyte involved is sodium, the issue is often water excess rather than sodium deficiency. Supplementation for these people may correct the electrolyte imbalance but at the expense of volume overload.
Isolated hyperchlorhidrosis (Carbonic anhydrase XII deficiency), a rare genetic disorder which results in a lifelong tendency to lose excessive amounts of sodium by sweating. Pancreatitis [ 12 ] Prolonged exercise and sweating, combined with drinking water without electrolytes is the cause of exercise-associated hyponatremia (EAH).
Malnutrition occurs when an organism gets too few or too many nutrients, resulting in health problems. [11] [12] Specifically, it is a deficiency, excess, or imbalance of energy, protein and other nutrients which adversely affects the body's tissues and form. [13] Malnutrition is a category of diseases that includes undernutrition and ...
