Sodium is a chemical element; it has symbol Na (from Neo-Latin natrium) and atomic number 11. It is a soft, silvery-white, highly reactive metal. Sodium is an alkali metal, being in group 1 of the periodic table. Its only stable isotope is 23 Na. The free metal does not occur in nature and must be prepared from compounds.
Salt comes from two main sources: sea water, and the sodium chloride mineral halite (also known as rock salt). Rock salt occurs in vast beds of sedimentary evaporite minerals that result from the drying up of enclosed lakes, playas, and seas. Salt beds may be up to 350 metres (1,150 ft) thick and underlie broad areas.
This evidence shows that while those with hypertension should primarily focus on reducing sodium to recommended levels, all groups should seek to maintain a healthy level of sodium intake of between 4 and 5 grams (equivalent to 10-13 g salt) a day. [75] One of the two most prominent dietary risks for disability in the world are diets high in ...
High sodium consumption (5 g or more of salt per day) and insufficient potassium intake (less than 3.5 grams (0.12 oz) per day) have been linked to high blood pressure and increased risk of heart disease, stroke, and kidney disease. [6] [7] As an essential nutrient, sodium is involved in numerous cellular and organ functions. Several national ...
If the sodium, saturated fat and added sugar contents are 5% or less on the nutrition label, it means that the food item is low in those nutrients, she explained. Beyond that, look at the ...
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.
The organization picked menu items perceived to be "healthy" at each spot and found that they were, in fact, not so good for anyone's health, with higher-than-ideal levels of sodium, saturated fat ...
