Salt for human consumption is produced in different forms: unrefined salt (such as sea salt), refined salt (table salt), and iodized salt. Sea salt, obtained by evaporating Seawater, is used in Cooking and Cosmetics. It is a crystalline solid, white, pale pink or light grey in color, normally obtained from sea water or rock deposits. Seawater is Water from a Sea or Ocean. On average seawater in the world's oceans has a Salinity of about 3 Edible rock salts may be slightly greyish in color due to this mineral content.
Chloride and sodium ions, the two major components of salt, are necessary for the survival of all known living creatures, including humans. Salt is involved in regulating the water content (fluid balance) of the body. Water is a common Chemical substance that is essential for the survival of all known forms of Life. Salt cravings may be caused by trace mineral deficiencies as well as by a deficiency of sodium chloride itself. Conversely, overconsumption of salt increases the risk of health problems, including high blood pressure. Hypertension, also referred to as high blood pressure, HTN or HPN, is a medical condition in which the Blood pressure is chronically elevated
Human beings have enjoyed canning and artificial refrigeration for only a couple of centuries; for the countless millennia before then, salt provided the best-known preservative of food, especially meat. Salt 's ability to preserve food was a foundation of Civilization.

Hallstatt gave its name to the Celtic archaeological culture that began mining for salt in the area in around 800 B. The Hallstatt culture was the predominant Celts (ˈkɛlts or /ˈsɛlts/, see Names of the Celts In addition to its usual meaning in Social science, in Archaeology, the term culture is also used in reference to several related concepts unique to C. Around 400 B. C. , the Hallstatt Celts, who had heretofore mined for salt, began flushing the salt out of mines as brine and boiling off the excess water. A salt mine is an operation involved in the extraction of salt from Rock salt or halite a type of evaporitic deposit In the United States and the United Kingdom virtually all domestic salt is obtained by solution mining of underground salt formations During the first millennium B. C. , Celtic communities grew rich trading salt and salted meat to Ancient Greece and Ancient Rome in exchange for wine and other luxuries.

There are thirty-five verses which reference salt in the English translation of the Bible (King James Version), the earliest being the story of Lot's wife, who was turned into a pillar of salt when she disobediently looked back at the wicked cities of Sodom (Genesis 19:26). Etymology According to the Online Etymology Dictionary, the word bible is from Latin biblia, traced from the same word through Medieval Latin and Late Latin According to the Bible and the Quran, Lot ( Arabic: لوط, Lūṭ |; "Hidden covered" was the Nephew When King Abimelech destroyed the city of Shechem he is said to have "sowed salt on it;" a phrase expressing the completeness of its ruin. Shechem ( Sichem, Shkhem or Shachmu, Hebrew: שְׁכֶם / שְׁכָם, Standard (Judges 9:45. ) In the Sermon on the Mount, Jesus referred to his followers as the "salt of the earth". In the Gospel of St Matthew, the Sermon on the Mount is a compilation of Jesus' sayings epitomizing his moral teaching. Jesus of Nazareth (7–2 BC / BCE —26–36 AD / CE) The apostle Paul also encouraged Christians to "let your conversation be always full of grace, seasoned with salt" (Colossians 4:6).
Salt is mandatory in the rite of the Tridentine Mass. The Tridentine Mass (Missa Tridentina is the form of the Roman Rite Mass contained in the typical editions of the Roman Missal that were published Salt is used in the third item (which includes an Exorcism) of the Celtic Consecration (cf.

Different natural salts have different mineralities, giving each one a unique flavor. Sea salt, obtained by evaporating Seawater, is used in Cooking and Cosmetics. Halite is the Mineral form of Sodium chloride, Na[[chlorine Cl]] commonly known as rock salt. Fleur de sel ("Flower of salt" in French) is a hand-harvested Sea salt collected by workers who scrape only the top layer of salt before it sinks Fleur de sel, natural sea salt harvested by hand, has a unique flavor varying from region to region. Fleur de sel ("Flower of salt" in French) is a hand-harvested Sea salt collected by workers who scrape only the top layer of salt before it sinks
Some advocates for sea salt assert that unrefined sea salt is more healthy than refined salts.  However, completely raw sea salt is bitter due to magnesium and calcium compounds, and thus is rarely eaten. The refined salt industry cites scientific studies saying that raw sea and rock salts do not contain enough iodine salts to prevent iodine deficiency diseases. Iodine (ˈaɪədaɪn ˈaɪədɪn or /ˈaɪədiːn/ from ιώδης iodes "violet" is a Chemical element that has the symbol I and Atomic Iodine is an essential Trace element; the Thyroid hormones Thyroxine and Triiodotyronine contain iodine 
Unrefined sea salts are also commonly used as ingredients in bathing additives and cosmetic products. One example are bath salts, which uses sea salt as its main ingredient and combined with other ingredients used for its healing and therapeutic effects. The term bath salts refers to a range of water-soluble usually inorganic solid products designed to be added to a bath either to improve cleaning provide a medical improvement Sea salt, obtained by evaporating Seawater, is used in Cooking and Cosmetics.
Refined salt, which is most widely used presently, is mainly sodium chloride. Food grade salt accounts for only a small part of salt production in industrialised countries (3% in Europe) although world-wide, food uses account for 17. 5% of salt production. The majority is sold for industrial use. Salt has great commercial value, because it is a necessary ingredient in the manufacturing of many things. A few common examples include: the production of pulp and paper, setting dyes in textiles and fabrics, and the making of soaps and detergents.
The manufacture and use of salt is one of the oldest chemical industries.  Salt is also obtained by evaporation of sea water, usually in shallow basins warmed by sunlight; salt so obtained was formerly called bay salt, and is now often called sea salt or solar salt. Seawater is Water from a Sea or Ocean. On average seawater in the world's oceans has a Salinity of about 3 Sunlight, in the broad sense is the total spectrum of the Electromagnetic radiation given off by the Sun. Today, most refined salt is prepared from rock salt: mineral deposits high in salt. These rock salt deposits were formed by the evaporation of ancient salt lakes.  These deposits may be mined conventionally or through the injection of water. Mining is the extraction of valuable Minerals or other geological materials from the earth usually (but not always from an Ore body Injected water dissolves the salt, and the brine solution can be pumped to the surface where the salt is collected. Brine (lat saltus) is Water saturated or nearly saturated with Salt (NaCl
After the raw salt is obtained, it is refined to purify it and improve its storage and handling characteristics. Purification usually involves recrystallization. In recrystallization, a brine solution is treated with chemicals that precipitate most impurities (largely magnesium and calcium salts).  Multiple stages of evaporation are then used to collect pure sodium chloride crystals, which are kiln-dried. Kilns are thermally insulated chambers or Ovens in which controlled temperature regimes are produced
Since the 1950s it has been common to add a trace of sodium hexacyanoferrate(II) to the brine; this acts as an anticaking agent by promoting irregular crystals. Anticaking agents are used in such things as table Salt to keep the product from forming lumps making it better for packaging transport and for the consumer  Other anticaking agents (and potassium iodide, for iodised salt) are generally added after crystallization. Anticaking agents are used in such things as table Salt to keep the product from forming lumps making it better for packaging transport and for the consumer Potassium iodide is an Inorganic compound with formula K[[iodide I]] These agents are hygroscopic chemicals which absorb humidity, keeping the salt crystals from sticking together. Hygroscopy is the ability of a substance to attract Water Molecules from the surrounding environment through either absorption or Adsorption Humidity is the amount of water vapor in the air In daily language the term "humidity" is normally taken to mean Relative humidity. Some anticaking agents used are tricalcium phosphate, calcium or magnesium carbonates, fatty acid salts (acid salts), magnesium oxide, silicon dioxide, calcium silicate, sodium alumino-silicate, and alumino-calcium silicate.

Table salt is refined salt, 99% sodium chloride. For sodium chloride in the diet see Salt. Sodium chloride, also known as common salt, table salt, or Halite, is a  It usually contains substances that make it free flowing (anticaking agents) such as sodium silicoaluminate or magnesium carbonate. It is common practice to put a few grains of uncooked rice or half a dry cracker (such as Saltine) in salt shakers to absorb extra moisture when anticaking agents are not enough. Rice is a Cereal foodstuff which forms an important part of the diet of many people worldwide and as such it is a staple food for many Whereas pure NaCl has a density of 2. 165 gm/cc, table salt has a density of 1. 22 gm/cc.
In many East Asian cultures, salt is not traditionally used as a condiment.  However, condiments such as soy sauce, fish sauce and oyster sauce tend to have a high salt content and fill much the same role as a salt-providing table condiment that table salt serves in western cultures.

Sodium is one of the primary electrolytes in the body. Sodium (ˈsoʊdiəm is an element which has the symbol Na( Latin natrium, from Arabic natrun) atomic number 11 atomic mass 22 An electrolyte is any substance containing free Ions that behaves as an electrically conductive medium All four cationic electrolytes (sodium, potassium, magnesium, and calcium) are available in unrefined salt, as are other vital minerals needed for optimal bodily function. Too much or too little salt in the diet can lead to muscle cramps, dizziness, or even an electrolyte disturbance, which can cause severe, even fatal, neurological problems. Cramps, sometimes called Charley horses are unpleasant often painful sensations caused by contraction or over shortening of Muscles Cramps can be caused by cold Many different terms are often used to describe what is collectively known as dizziness. Electrolytes play a vital role in maintaining Homeostasis within the body  Drinking too much water, with insufficient salt intake, puts a person at risk of water intoxication (hyponatremia). Water intoxication (also known as hyperhydration or water poisoning) is a potentially fatal disturbance in Brain functions that results when the Hyponatremia ( British: hyponatraemia) is an Electrolyte disturbance (disturbance of the salts in the blood in which the Sodium ( Natrium Salt is even sometimes used as a health aid, such as in treatment of dysautonomia. Dysautonomia is any disease or malfunction of the Autonomic nervous system. 
People's risk for disease due to insufficient or excessive salt intake varies due to biochemical individuality. Some have asserted that while the risks of consuming too much salt are real, the risks have been exaggerated for most people, or that the studies done on the consumption of salt can be interpreted in many different ways.  
Excess salt consumption has been linked to:
Sea salt (an unrefined form of salt made by evaporating sea water) is often sold for use as a condiment. Because it contains trace amounts of other minerals which are removed in the refining process, it may have health advantages over normal table salt.  Certain sea salts are also used in the production of bath salts and cosmetic products. The term bath salts refers to a range of water-soluble usually inorganic solid products designed to be added to a bath either to improve cleaning provide a medical improvement

In the United Kingdom the Scientific Advisory Committee on Nutrition (SACN) recommended in 2003 that, for a typical adult, the Reference Nutrient Intake is 4 g salt per day (1. The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom, the UK or Britain,is a Sovereign state located 6 g or 70 mmol sodium). However, average adult intake is two and a half times the Reference Nutrient Intake for sodium. SACN states, "The target salt intakes set for adults and children do not represent ideal or optimum consumption levels, but achievable population goals. " The Food Safety Authority of Ireland endorses the UK targets. Ireland ( Irish: Éire, ˈeːrʲə is a country in north-western Europe.

In the United States, the Food and Drug Administration itself does not make a recommendation, but refers readers to Dietary Guidelines for Americans 2005. The United States of America —commonly referred to as the These suggest that US citizens should consume less than 2,300 mg of sodium (= 2. 3 g sodium = 5. 8 g salt) per day. 
UK: The Food Standards Agency defines the level of salt in foods as follows: "High is more than 1. The Food Standards Agency is a Non-ministerial government department of the Government of the United Kingdom. 5g salt per 100g (or 0. 6g sodium). Low is 0. 3g salt or less per 100g (or 0. 1g sodium). If the amount of salt per 100g is in between these figures, then that is a medium level of salt. " In the UK, foods produced by some supermarkets and manufacturers have ‘traffic light’ colors on the front of the pack: Red (High), Amber (Medium), or Green (Low). 
USA: The FDA Food Labeling Guide stipulates whether a food can be labelled as "free", "low", or "reduced/less" in respect of sodium. When other health claims are made about a food (e. g. low in fat, calories, etc. ), a disclosure statement is required if the food exceeds 480mg of sodium per 'serving. '
In 2004, Britain's Food Standards Agency started a public health campaign called "Salt - Watch it", which recommends no more than 6g of salt per day; it features a character called Sid the Slug and was criticised by the Salt Manufacturers Association (SMA).

Salt intake can be reduced by simply reducing the quantity of salty foods in a diet, without recourse to salt substitutes. High intake of table salt ( Sodium chloride) is associated with high blood pressure and an increased risk of cardiovascular disease Salt substitutes have a taste similar to table salt and contain mostly potassium chloride, which will increase potassium intake. The Chemical compound potassium chloride (KCl is a Metal Halide salt composed of Potassium and Chlorine. Potassium (pəˈtæsiəm is a Chemical element. It has the symbol K (kalium from qalīy Atomic number 19 and Atomic mass 39 Excess potassium intake can cause hyperkalemia. Hyperkalemia ( AE) or Hyperkalaemia ( BE) is an elevated blood level of the Electrolyte Potassium. Various diseases and medications may decrease the body's excretion of potassium, thereby increasing the risk of hyperkalemia. Medication, also referred to as medicine, can be loosely defined as any substance intended for use in the diagnosis cure mitigation treatment or prevention of disease If you have kidney failure, heart failure or diabetes, seek medical advice before using a salt substitute.
