Salt intake is a major regulator of blood pressure. There is evidence that those who develop high blood pressure have an underlying defect in the ability of the kidney to excrete salt. It has been suggested that this results in a greater tendency to retain sodium and an increased compensatory response that is responsible for the rise in blood pressure. There is also evidence suggesting that sma...

An ouabain-like factor has been implicated repeatedly in salt-sensitive hypertension as a natriuretic agent. However, the response of plasma ouabain-like factor to acute and chronic variation of body sodium is unclear. We studied 138 patients with essential hypertension who underwent an acute volume expansion/contraction maneuver (2 days) and 20 patients who entered a blind randomized crossover...

Excessive salt/sodium (Sodium > 2 grams/day, equivalent to 5 g salt/day) and low potassium (less than 3.5 grams/day) intake increases the risk of heart attack stroke. To fight against cardiovascular diseases, nutritional strategy is regulate dietary according set standards.

The plasma sodium concentration has a direct effect on blood pressure in addition to its effects on extracellular volume regulated through changes in the endothelium. The mechanism for elevated blood pressure seen with habitually increased salt intake is unclear, especially the effect of salt in a single meal on plasma sodium concentration and blood pressure. To resolve this we compared the eff...

Background: Cerebral Salt Wasting Syndrome (CSWS) refers to the process of intracranial lesions, sodium salt loss by hypothalamus-renal pathway and caused clinical manifestations syndrome of high urinary sodium, hyponatremia, hypovolemia. The clinical manifestations and laboratory are similar to syndrome of inappropriate antidiuretic hormone secretion (SIADH). It is easy to be misdiagnosed. Cas...

Salt has been used as a food preservative and part of the human diet for thousands of years. Consequently, human dietary sodium chloride intake is significantly higher than that needed to sustain life. Fortunately, kidneys function to regulate sodium chloride excretion to maintain proper levels of sodium chloride and extracellular volume when dietary salt intake changes. If the kidneys are prop...

Iron (Fe) deficiency is a major human health concern in areas of the world in which diets are often Fe deficient. In the current study, we aimed to identify appropriate methods and optimal dosage for Fe fortification of lentil (Lens culinaris Medik.) dal with FeSO₄·7H₂O (ferrous sulphate hepta-hydrate), NaFeEDTA (ethylenediaminetetraacetic acid iron (III) sodium salt) and FeSO₄·H₂O (ferrous sul...

OBJECTIVE To review the physiology and cardiovascular effects of the commonly used intravenous electrolytes. DATA SOURCES Abstracts, articles and published reviews of studies reported from 1966 to 2000 and identified through a MEDLINE search on cardiac arrhythmias and electrolytes. SUMMARY OF REVIEW While isotonic saline solutions are used to improve the haemodynamic status in critically il...

BACKGROUND Takeaway food has a relatively poor nutritional profile. Providing takeaway outlets with reduced-holed salt shakers is one method thought to reduce salt use in takeaways, but effects have not been formally tested. We aimed to determine if there was a difference in sodium content of standard fish and chip meals served by Fish & Chip Shops that use standard (17 holes) versus reduced-ho...

We are beginning to understand why humans ingest so much salt. Here we address three issues: The first is whether our salt appetite is similar to that in animals, which we understand well. Our analysis suggests that this is doubtful, because of important differences between human and animal love of salt. The second issue then becomes how our predilection for salt is determined, for which we hav...
