Along the Sahara, the Tuareg maintain routes especially for the transport of salt by Azalai (salt caravans). In 1960, the caravans still transported some 15,000 tons of salt, but this trade has now declined to roughly a third of this figure.
Salzburg, Hallstatt, and Hallein lie on the river Salzach in central Austria, within a radius of no more than 17 kilometres. Salzach literally means "salt water" and Salzburg "salt city", both taking their names from the ජර්මානු word for salt, Salz.
Hallstatt gave its name to the Celtic archaeological culture that began mining for salt in the area in around 800 BC. Around 400 BC, the Hallstatt Celts, who had heretofore mined for salt, began open pan salt making. During the first millennium BC, Celtic communities grew rich trading salt and salted meat to Ancient Greece and Ancient Rome in exchange for wine and other luxuries.
It is widely, though incorrectly, believed that troops in the Roman army were paid in salt. Even widely respected historical works repeat this error.:63 The word salad literally means "salted," and comes from the ancient Roman practice of salting leaf vegetables.:64
Mahatma Gandhi led at least 100,000 people on the "Dandi March" or "Salt Satyagraha", in which protesters made their own salt from the sea, which was illegal under British rule, as it avoided paying the "salt tax". This civil disobedience inspired millions of common people, and elevated the Indian independence movement from an elitist struggle to a national struggle.
ලුණු ප්රභේද[සංස්කරණය කරන්න]
Unrefined ලුණු[සංස්කරණය කරන්න]
Different natural salts have different mineralities, giving each one a unique flavor. Fleur de sel, natural sea salt harvested by hand, has a unique flavor varying from region to region. In traditional Korean cuisine, so-called "bamboo salt" is prepared by roasting salt  in a bamboo container plugged with mud at both ends. This product absorbs minerals from the bamboo and the mud, and has been shown to increase the anticlastogenic and antimutagenic properties of doenjang.
Completely raw sea salt is bitter because of 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.
Unrefined sea salts are also commonly used as ingredients in bathing additives and cosmetic products. One example is bath salts, which uses sea salt as its main ingredient and combined with other ingredients used for its healing and therapeutic effects.
Refined salt[සංස්කරණය කරන්න]
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 worldwide, 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 can be 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. Rock salt deposits are formed by the evaporation of ancient salt lakes, and may be mined conventionally or through the injection of water. Injected water dissolves the salt, and the brine solution can be pumped to the surface where the salt is collected.
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.
Since the 1950s it has been common practice in the United Kingdom to add a trace amount of sodium ferrocyanide to the brine; this acts as an anticaking agent by promoting irregular crystals. The safety of sodium ferrocyanide as a food additive was confirmed in the United Kingdom in 1993. Some anticaking agents used are tricalcium phosphate, calcium or magnesium carbonates, fatty acid salts (acid salts), magnesium oxide, silicon dioxide, calcium silicate, sodium aluminosilicate, and calcium aluminosilicate. Both the European Union and the United States Food and Drug Administration (FDA) permitted the use of aluminum in the latter two compounds. The refined salt is then ready for packing and distribution.
Table salt[සංස්කරණය කරන්න]
Table salt is refined salt, which contains about 97% to 99% sodium chloride. It usually contains substances that make it free-flowing (anti-caking agents) such as sodium silicoaluminate or magnesium carbonate. Some people also add a desiccant, such as a few grains of uncooked rice, in salt shakers to absorb extra moisture and help break up clumps when anti-caking agents are not enough. Table salt has a particle density of 2.165 g/cm3, and a bulk density (dry, ASTM D 632 gradation) of about 1.154 g/cm3.
Salty condiments[සංස්කරණය කරන්න]
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.
Health effects[සංස්කරණය කරන්න]
සෝඩියම් is one of the primary electrolytes in the body. 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 electrolyte disturbance, which can cause neurological problems, or death. Drinking too much water, with insufficient salt intake, puts a person at risk of water intoxication (hyponatremia). Salt is sometimes used as a health aid, such as in treatment of dysautonomia.
Excess salt consumption is linked with a number of conditions including:
- Stroke and cardiovascular disease.
- Hypertension (high blood pressure): "Since 1994, the evidence of an association between dietary salt intakes and blood pressure has increased. The data have been consistent in various study populations and across the age range in adults." A large scale study from 2007 has shown that people with high-normal blood pressure who significantly reduced the amount of salt in their diet decreased their chances of developing cardiovascular disease by 25% over the following 10 to 15 years. Their risk of dying from cardiovascular disease decreased by 20%.
- Left ventricular hypertrophy (cardiac enlargement): "Evidence suggests that high salt intake causes left ventricular hypertrophy, a strong risk factor for cardiovascular disease, independently of blood pressure effects." "...there is accumulating evidence that high salt intake predicts left ventricular hypertrophy." Excessive salt (sodium) intake, combined with an inadequate intake of water, can cause hypernatremia. It can exacerbate renal disease.
- Edema (BE: oedema): A decrease in salt intake has been suggested to treat edema (fluid retention).
- Duodenal ulcers and gastric ulcers
- Osteoporosis: One report shows that a high salt diet does reduce bone density in women. Yet "While high salt intakes have been associated with detrimental effects on bone health, there are insufficient data to draw firm conclusions."
- Gastric cancer (stomach cancer) is associated with high levels of sodium, "but the evidence does not generally relate to foods typically consumed in the UK." However, in Japan, salt consumption is higher.
- Death: Ingestion of large amounts of salt in a short time (about 1 g per kg of body weight) can be fatal. Deaths have also resulted from attempted use of salt solutions as emetics, forced salt intake, and accidental confusion of salt with sugar in child food.
The Cochrane Collaboration found that "a modest and long term reduction in population salt intake [...] would result in a lower population blood pressure, and a reduction in strokes, heart attacks and heart failure. Furthermore, our study is consistent with the fact that the lower the salt intake, the lower the blood pressure." However, salt consumption is not linked to asthma.
The risk for disease due to insufficient or excessive salt intake varies because of 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.
Some isolated cultures, such as the Yanomami in South America, have been found to consume little salt, possibly an adaptation originated in the predominantly vegetarian diet of human primate ancestors. However, the low salt diets of the Yanomamo Indians does not result in their low blood pressure, this has been attributed to their lack of a D/D genotype.
Recommended intake[සංස්කරණය කරන්න]
In the United Kingdom the Scientific Advisory Committee on Nutrition (SACN) recommended in 2003 that, for a typical adult, the Reference Nutrient Intake (RNI) is 4 g salt per day (1.6 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.
The NHMRC in ඕස්ට්රේලියාව was not able to define a recommended dietary intake (RDI). It defines an Adequate Intake (AI) for adults of 460–920 mg/day and an Upper Level of intake (UL) of 2300 mg/day.
In the United States, the Food and Drug Administration itself does not make a recommendation, but refers readers to Dietary Guidelines for Americans 2005. These suggest that US citizens should consume less than 2,300 mg of sodium (= 2.3 g sodium = 5.8 g salt) per day.
Meta-analysis in 2009 found that the sodium consumption of 19,151 individuals from 33 countries fit into the narrow range of 2,700 to 4,900 mg/day. The small range across many cultures, together with animal studies, suggest that sodium intake is tightly controlled by feedback loops in the body, making recommendations to reduce sodium consumption below 2,700 mg/day potentially futile.
UK: The Food Standards Agency defines the level of salt in foods as follows: "High is more than 1.5 g salt per 100 g (or 0.6 g sodium). Low is 0.3 g salt or less per 100 g (or 0.1 g sodium). If the amount of salt per 100 g 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 480 mg of sodium per 'serving.'
Normal salt itself contains 40 g of sodium per 100 g of salt.
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). The Advertising Standards Authority did not uphold the SMA complaint in its adjudication. In March 2007, the FSA launched the third phase of their campaign with the slogan "Salt. Is your food full of it?" fronted by comedienne Jenny Eclair.
The University of Tasmania's Menzies Research Institute maintains a website to educate people about the problems of a salt-laden diet.
Consensus Action on Salt and Health (CASH) established in 1996, actively campaigns to raise awareness of the harmful health effects of salt. The 2008 focus includes raising awareness of high levels of salt hidden in sweet foods and marketed towards children.
Iodized salt (BrE: iodised salt) is table salt mixed with a minute amount of potassium iodide, sodium iodide, or sodium iodate. Iodized salt is used to help reduce the incidence of iodine deficiency in humans. Iodine deficiency commonly leads to thyroid gland problems, specifically endemic goiter, a disease characterized by a swelling of the thyroid gland, usually resulting in a bulbous protrusion on the neck. While only tiny quantities of iodine are required in the diet to prevent goiter, the United States Food and Drug Administration recommends (21 CFR 101.9 (c)(8)(iv)) 150 micrograms of iodine per day for both men and women. Iodized table salt has significantly reduced disorders of iodine deficiency in countries where it is used. Iodine is important to prevent the insufficient production of thyroid hormones (hypothyroidism), which can cause goitre, cretinism in children, and myxedema in adults.
Table salt is mainly employed in cooking and as a table condiment. The amount of iodine and the specific iodine compound added to salt varies from country to country. In the United States, iodized salt contains 46-77 ppm, while in the UK the iodine content of iodized salt is recommended to be 10–22 ppm. Today, iodized salt is more common in the United States, ඕස්ට්රේලියාව and නවසීලන්තය than in the United Kingdom.
In some European countries where drinking water fluoridation is not practiced, fluorinated table salt is available. In France, 35% of sold table salt contains either sodium fluoride or potassium fluoride.[තහවුරු කරන්න] Another additive, especially important for pregnant women, is folic acid (Vitamin B9), which gives the table salt a yellow color.
In Canada, at least one brand (Windsor salt) contains invert sugar.[තහවුරු කරන්න]Sodium ferrocyanide, also known as yellow prussiate of soda, is sometimes added to salt as an anti-caking agent. The additive is considered safe for human consumption.
Salt substitutes[සංස්කරණය කරන්න]
Salt intake can be reduced by simply reducing the quantity of salty foods in a diet, without recourse to salt substitutes. Salt substitutes have a taste similar to table salt and contain mostly potassium chloride, which will increase potassium intake. Excess potassium intake can cause hyperkalemia. Various diseases and medications may decrease the body's excretion of potassium, thereby increasing the risk of hyperkalemia. Those who have kidney failure, heart failure or diabetes should seek medical advice before using a salt substitute. One manufacturer, LoSalt, has issued an advisory statement that those taking the following prescription drugs should not use a salt substitute: amiloride, triamterene, Dytac, spironolactone (Aldactone), and eplerenone (Inspra).
Low salt diets[සංස්කරණය කරන්න]
In 2002, total world production (of sodium chloride in general, not just table salt) was estimated at 210 million tonnes, the top five producers being the United States (40.3 million tonnes), China (32.9), Germany (17.7), India (14.5), and Canada (12.3). By 2007, China had become the world's largest salt producer, surpassing the United States.
Non-dietary aspects[සංස්කරණය කරන්න]
In religion[සංස්කරණය කරන්න]
In the Hebrew Bible, thirty-five verses mention salt, the earliest being the story of Lot's wife, who was turned into a pillar of salt when she looked back at the cities of Sodom and Gomorrah (Genesis 19:26) as the 'Lord' destroyed them. When King Abimelech destroyed the city of Shechem, he is said to have "sown salt on it," probably as a curse on anyone who would re-inhabit it. (Judges 9:45)
In the Christian New Testament, six verses mention salt. In the Sermon on the Mount, Jesus referred to his followers as the "salt of the earth". The apostle Paul also encouraged Christians to "let your conversation be always full of grace, seasoned with salt" (Colossians 4:6).
In one of the Hadith recorded in Sunan Ibn Majah, Prophet Muhammad is reported to have said that: "Salt is the master of your food. God sent down four blessings from the sky - fire, water, iron and salt"
Salt is mandatory in the rite of the Tridentine Mass. Salt is used in the third item (which includes an Exorcism) of the Celtic Consecration (cf. Gallican rite) that is employed in the consecration of a church. Salt may be added to the water "where it is customary" in the Roman Catholic rite of Holy water.
Salt is considered to be a very auspicious substance in Hindu mythology, and is used in particular religious ceremonies like housewarmings and weddings.
In Judaism, it is recommended to have either a salty bread or to add salt to the bread if this bread is unsalted when doing Kidush for Shabat. It is customary to spread some salt over the bread or to dip the bread in a little salt when passing the bread around the table after the Kidush. To preserve the covenant between their people and God, Jews dip the Sabbath bread in salt.
In Wicca, salt is symbolic of the element Earth. It is also believed to clense an area of and harmful or negative energies.
