喜馬拉雅粉鹽是源自巴基斯坦旁遮普地區(qū)，靠近喜馬拉雅山麓的一種鹽。一些人認(rèn)為喜馬拉雅粉鹽是一種最純凈的鹽，認(rèn)為它促進(jìn)一些健康益處。
但是這種鹽確系名副其實的“健康”鹽嗎？這篇文章將探討這種異國鹽的可能益處。喜馬拉雅粉鹽化學(xué)成分與食鹽類似，大約98%部分含鈉氯化物；其余部分含幾種礦物質(zhì)，比如鉀、鎂、鈣等等，這些成分使此鹽呈粉色。這些成分也使喜馬拉雅粉鹽嘗起來與食鹽不同。與食鹽一樣，這種鹽可以用作烹調(diào)、調(diào)味膳食、保存食物。喜馬拉雅粉鹽有時也用于佐菜、烹調(diào)等等，一些人將喜馬拉雅粉鹽用于鹽浴。也可以購買用粉鹽制成的燈和蠟燭底座。鈉是見于鹽的主要礦物質(zhì)，身體一些功能需要它。它可支持：收縮和放松肌肉
維持適當(dāng)?shù)囊后w平衡，預(yù)防脫水
發(fā)送神經(jīng)系統(tǒng)脈沖
預(yù)防低血壓
近期研究建議吃鹽可降低感染風(fēng)險，殺滅有害細(xì)菌。
一項對動物的研究，使研究者推斷，鹽可能對抑郁癥的癥狀具有積極作用。
粉鹽富含礦物質(zhì)成分，一些資源說，喜馬拉雅粉鹽含有約84種不同礦物質(zhì)。
由于鹽98%部分是鈉氯化物，意味著只有2%是由各種礦物質(zhì)構(gòu)成，從而使粉鹽正常攝入量得到相對有限的礦物質(zhì)，這些鹽中的少量礦物質(zhì)貌似不太可能提供可觀或顯著的健康益處。
一些人相信喜馬拉雅粉鹽比常規(guī)食鹽含鈉量低，然而，兩種鹽約98%均由鈉氯化物構(gòu)成。由于粉鹽比食鹽結(jié)晶較大，技術(shù)上而言，每茶匙粉鹽含鈉較少，它也比食鹽更有鹽味，意味著人們可以少用粉鹽而取得相同滋味。然而，粉鹽也有更小顆粒的，跟接近于常規(guī)鹽。在調(diào)味食物和計量鈉攝入時要考慮到這點。美國心臟協(xié)會（AHA）建議，超過75%的鈉攝入來自用鹽加工和制備的食品中，那么一餐中就不必添加太多食鹽。一些人聲稱喜馬拉雅粉鹽比食鹽更自然，該聲稱貌似有價值。食鹽通常是精細(xì)粉，并摻有抗塊結(jié)成分，以預(yù)防結(jié)塊，比如如鋁硅酸鈉或碳酸鎂。喜馬拉雅粉鹽較少人為加工，通常不含添加素。
一些人相信在膳食或飲料中加一撮粉鹽，有助于身體獲得理想的液體平衡，預(yù)防脫水。這是真的，鈉對于恰當(dāng)?shù)囊后w平衡是必須的。然而，除了喜馬拉雅粉鹽，鈉也源于其他資源。碘是一種身體維持恰當(dāng)甲狀腺功能和細(xì)胞新陳代謝所必須的礦物質(zhì)。含碘鹽是這種礦物質(zhì)的另一種常見來源。美國大約75%的家庭食用含碘鹽。
雖然喜馬拉雅粉鹽可能自然含一些碘，它可能比加碘鹽含碘少，因此，碘缺乏者，或有碘缺乏風(fēng)險者，如果食用粉鹽替代食鹽的話，可能需要別的碘來源。雖然鈉對于維持生命是必要的，監(jiān)控任何類型鹽的攝入是重要的。鈉只需要少量，太多對健康有負(fù)面影響。患有腎臟、心臟、肝組織問題的人，或鈉限制膳食的人，應(yīng)該監(jiān)控其鈉攝入，限制所有鹽，包括喜馬拉雅粉鹽的食用。甚至健康者應(yīng)該監(jiān)控其鈉攝入量。疾病控制和預(yù)防中心（CDC）2016年報告指出，超過90%兒童、89%成人鈉攝入量超過推薦量。針對美國人的《2015-2020年膳食指南》推薦人們每天鈉攝入量少于2300毫克（mg），這相當(dāng)于每天最多1茶匙常規(guī)食鹽。高血壓患者應(yīng)該控制每天鈉攝入量為1500毫克，咨詢膳食專家，做出膳食調(diào)整，可限制鈉攝入。鹽含有40%鈉，當(dāng)考慮到鈉攝入量時，了解一定量鹽含多少鈉有幫助。1/4茶匙鹽：575毫克鈉
1/2茶匙鹽：1150毫克鈉
3/4茶匙鹽：1725毫克鈉
1茶匙鹽：2300毫克鈉
多數(shù)人攝入量高于此。當(dāng)人們攝入鈉高于其所需時，其腎臟試圖通過尿液排出多余的鈉，如果腎臟不能排出足夠的鈉，它開始在細(xì)胞間液體中積累，稱為填隙液。這導(dǎo)致水量和血液量增加，對心臟和血管造成格外負(fù)擔(dān)。一些嚴(yán)重的健康問題與高鈉攝入有關(guān)，包括：高血壓
心臟病
中風(fēng)
肝損傷
骨質(zhì)疏松癥
腎臟疾病
鹽攝入太多，過度刺激免疫系統(tǒng)，從而導(dǎo)致自動免疫系統(tǒng)疾病，比如復(fù)發(fā)硬化癥、風(fēng)濕性關(guān)節(jié)炎、狼瘡、牛皮癬。2015年的研究建議：鹽攝入量直接與肥胖有關(guān)，每日鹽攝入量增加1克，導(dǎo)致成人和兒童增加逾25%的肥胖風(fēng)險。目前，沒有科學(xué)證據(jù)顯示喜馬拉雅粉鹽比常規(guī)食鹽具有更多健康益處。用喜馬拉雅粉鹽替代精細(xì)食鹽可能有助于減少鈉攝入，但是也要像其它鹽一樣，要確保食用適量。Pink Himalayan salt is a type of rock salt from the Punjab region of Pakistan, near the foothills of the Himalayas.Some people describe pink Himalayan salt as one of the purest salts available, and say it boasts several health benefits.But does this salt earn its place among the'healthier' salts? This article explores the possible benefits ofthis exotic salt.What is pink Himalayan salt?Pink Himalayan salt is chemically similar to table salt. It contains up to 98 percent sodium chloride.The rest of the salt consists of trace minerals, such as potassium, magnesium, and calcium. These give the salt its light pink tint.These minerals also explain why Himalayan salt tastes different from regular table salt.People use this type of salt and common table salt in the same way: As part of cooking, to season meals, and to preserve food.Blocks of pink salt sometimes become serving dishes, cooking surfaces, and cutting boards. Some people also use pink Himalayan salt in place of bath salts. It is also possible to buy lamps and candle holders made of pink salt.Why does the body need salt?Sodium is an essential trace mineral found in salt. The body needs this for a variety of functions. It can support:Contracting and relaxing muscles
Maintaining proper fluid balance and preventing dehydration
Sending nervous system impulses
Preventing low blood pressure
Recent research has suggested that eating salt can reduce the risk of infection and kill harmful bacteria.
One study on animals has also led researchers to infer that salt may have a positive effect on symptoms of depression.
There are several claims about the health benefits associated with pink salt consumption. These include:Rich mineral content .Some sources say that pink Himalayan salt contains up to 84 different trace minerals.As it contains up to 98 percent sodium chloride, this means that only around 2 percent is made up of these various trace minerals. Given the relatively limited quantities in which people normally consume salt, and the tiny quantity of these minerals in the salt, they are unlikely to provideany measurable or significant health benefits.Some people believe that pink Himalayan salt is lower in sodium than regular table salt. However, both types consist of approximately 98 percent sodium chloride.As pink salt often has larger crystals than table salt, it technically contains less sodium per teaspoon. It also has a saltier flavor than table salt, meaning that a person can use less salt in a serving to achieve the same taste.However, pink salt is also available in a smaller granule size that more closely resembles regular salt. Consider this when seasoning food and measuring sodium intake.The American Heart Association (AHA) advises that over 75 percent of sodium intake comes from the salt already present in processed and prepared foods. Table salt does not add the bulk of sodium content to ameal.Some claim that Himalayan salt is more natural than tablesalt. This claim appears to have merit.Table salt is usually heavily refined and mixed with anti-caking agents to prevent clumping, such as sodium aluminosilicate or magnesium carbonate, Himalayan salt is less artificial and does not usually contain additives.Some believe that adding a pinch of pink salt to meals or drinks can help the body achieve optimal fluid balance and prevent dehydration.It is true that sodium is necessary to maintain proper fluid balance. However, this is true of sodium from other sources as well as pink Himalayan salt.Bear the following points in mind if using pink Himalayan salt:Iodine is a mineral that the body needs for maintaining proper thyroid function and cell metabolism. Great sources of iodine include fish, sea vegetables, dairy, and eggs, among other foods.Iodized salt is another common source of this trace mineral.Approximately 75 percent of households in the United States use iodized salt.Although pink Himalayan salt may naturally contain some iodine, it most likely contains less iodine than iodized salt. Therefore, those who have iodine deficiency or are at risk of deficiency may need to source iodine elsewhere if using pink salt instead of table salt.Although sodium is necessary for preserving life, it is important to monitor the intake of any type of salt. While sodium is necessary in small quantities, too much can have a negative impact on health.Those with kidney, heart, or liver issues, or people on asodium-restricted diet, should monitor their sodium intake and limit their use of all salt, including pink Himalayan salt.Even people in good health should monitor sodium intake. A 2016 report from the Centers for Disease Control and Prevention(CDC) states that over 90 percent of children and 89 percent of adults consume more than the recommended amount of sodium.The 2015 to 2020 Dietary Guidelines for Americans recommend that people eat less than 2,300 milligrams (mg) of sodium daily. This equates to approximately 1 teaspoon of regular table salt per day.Those that have high blood pressure should limit sodium intake to 1500 mg per day. Speak with a dietitian to determine dietary changes that can be made to limit sodium intake.Salt contains 40 percent sodium. When being conscious of sodium intake, it can be helpful to know how much sodium is in certain amounts of salt.Certain quantities of salt contain the following amounts of sodium:1/4 teaspoon salt: 575 mg sodium
1/2 teaspoon salt: 1,150 mg sodium
3/4 teaspoon salt: 1,725 mg sodium
1 teaspoon salt: 2,300 mg sodium
Most people consume much more than this.When people take in more sodium than they need, their kidneys try to remove the excess through the urine. If the kidneys cannot remove enough sodium, it begins to build up in the fluid between cells, known as the interstitial fluid.This causes both water volume and blood volume to increase,putting additional strain on the heart and blood vessels.A number of serious health conditions are linked to high sodium intake, including:High blood pressure
Heart disease
Stroke
Liver damage
Osteoporosis
Kidney disease
Consuming too much salt might even contribute to autoimmune diseases, such as multiple sclerosis, rheumatoid arthritis, lupus,and psoriasis, as it over stimulates the immune system.Research from 2015 suggests a direct link between salt intake and obesity, with a 1-g-per-day increase in salt intake being linked to an increase of over 25 percent in the risk of obesity in both adults and children.At present, there is no scientific evidence to show that pink Himalayan salt provides more health benefits than regular table salt.Replacing fine-grain table salt with crystals of pink Himalayan salt may help to reduce sodium intake, but, as with any other salt,be sure to enjoy it in moderation.
