Himalayan salt is a popular alternative to table salt, marketed as a pure and natural product. It is mined in Pakistan and is believed to be protected from environmental contaminants due to its extraction process. However, with the growing concern over plastic pollution in food sources, consumers are increasingly curious about the presence of microplastics in Himalayan salt. While it is generally accepted that sea salt contains microplastics, the question remains whether Himalayan salt, with its different origin and processing methods, is also contaminated.

Himalayan salt is mined, not exposed to plastic pollution
Himalayan salt is mined from the Salt Range mountains in the Punjab region of Pakistan, hundreds of miles from the iconic snowy peaks of the Himalayas. The salt is extracted by hand, making it a more natural product than table salt, which requires huge industrial processes. The miners use explosives and dynamite just once to open the main entrance, after which they mine by hand using hammers, hand drills, and other tools. This method has been used for hundreds of years, although it is discouraged inside the mine due to the health risks posed by toxins and the need to preserve the crystalline structure of the salt.
The salt is primarily exported in bulk and is then processed in other countries for the consumer market. It is a popular product in the United States, although Pakistan has not benefited economically from this popularity. Pakistan's government now wants to trademark the salt and cash in on its popularity.
Himalayan salt is supposedly protected from environmental contaminants like plastic pollution due to the process of land mining. However, there has been a rise in microplastic contamination in mined salt, likely due to the addition of airborne microplastics during the processing and packaging of the salt. One study found that Himalayan pink salt from terrestrial sources had the highest microplastic load out of all the salt samples tested, although the concentration of microplastics was still very low at 1.63%.
Overall, Himalayan salt is mined, not exposed to plastic pollution during the extraction process, although it may be contaminated during processing and packaging.

Sea salt has microplastics, Himalayan salt is purer
Sea salt is derived from evaporated seawater and can vary in flavour, colour, and nutrient content. Modern sea salt production comes mainly from the Mediterranean Sea, but it can also be harvested from the Dead Sea and the Atlantic Ocean.
Sea salt is exposed to the rise of ocean pollutants, including the widespread presence of plastic. Microplastics, or plastic particles smaller than 5mm in diameter, make up about 92% of the 5.25 trillion plastic particles on the ocean surface. One study found that 90% of all sea salt tested contained microplastics.
Himalayan salt, on the other hand, is sourced from the Punjab region of Pakistan, near the Himalayan foothills. It is extracted by hand, making it a more natural product than table salt. The pink hue of Himalayan salt comes from the abundance of trace minerals, specifically iron.
While Himalayan salt may also contain microplastics introduced during processing, packaging, or transportation, its production through land mining supposedly protects it from environmental contaminants like plastic pollution. Therefore, Himalayan salt is considered purer than sea salt.
It is important to note that the health risks associated with consuming microplastics are still not fully understood, and further research is needed to isolate and understand the effects of these particles on the human body.

Himalayan salt is natural, table salt is processed
Himalayan salt is a type of salt that is mined in the Punjab region of Pakistan, near the Himalayas. It is believed to have been formed millions of years ago from the evaporation of ancient bodies of water. The salt is hand-extracted and minimally processed, yielding an unrefined product that is free of additives. It is composed of large grains of rock salt and contains traces of potassium, silicon, phosphorus, vanadium, and iron, which give it its distinctive pink colour.
Table salt, on the other hand, is highly processed and refined from salt mined around the world. It undergoes huge industrial processes, including pumping brine into evaporation vats, and is bleached and mixed with an aluminium anti-caking agent. While it is also composed of sodium chloride, it contains no trace minerals.
Some people believe that Himalayan salt provides health benefits due to its mineral content. It is said to be good for skin conditions like eczema and is considered a safer alternative to regular salt. However, there is little research to support these claims, and it has not been proven to have any unique health benefits compared to other dietary salt.
In terms of nutritional value, there is little difference between Himalayan salt and table salt. Both contain roughly the same amount of sodium per teaspoon and provide the same essential nutrient. However, it is worth noting that Himalayan salt may have lower sodium levels, with a teaspoon containing about 2,200 milligrams compared to 2,300 milligrams in table salt.
While Himalayan salt is generally considered a natural product, there have been concerns about microplastic contamination. Studies have shown that fine Himalayan salt samples had a very little fibre concentration of 1.63%, while coarse Himalayan salt from terrestrial sources was found to have the highest microplastic load among the tested samples. The contamination is likely due to the addition of airborne microplastics during the processing and packaging of the salt.

Microplastics are endocrine disruptors, a threat to human health
Himalayan salt is extracted through mining in Pakistan. It is supposed to be protected from environmental contaminants like plastic pollution due to the process of land mining. However, studies have shown that Himalayan salt contains microplastics, with one study finding that fine Himalayan salt had a plastic fibre concentration of 1.63%. The observed rise in microplastic contamination in mined salt is likely due to the addition of airborne microplastics during the processing and packaging of salts.
Microplastics are a threat to human health as they contain endocrine-disrupting chemicals (EDCs) and other harmful compounds. EDCs are exogenous substances that interfere with the endocrine system by altering the homeostasis of the endocrine system. They affect the functioning of organs that respond to hormonal signals, such as the hypothalamus, pituitary, thyroid, adrenal, and reproductive organs.
There are more than 1000 chemicals classified as EDCs, and they are known to alter the expression of various hormone receptors and interfere with the synthesis, secretion, transport, and action of hormones. This can lead to endocrine and developmental abnormalities, such as hormonal cancers (breast, prostate, testes), reproductive problems (genital malformations, infertility), metabolic disorders (diabetes, obesity), asthma, and neurodevelopmental conditions (learning disorders, autism spectrum disorders).
Some common EDCs that leach from plastics include bisphenol A, phthalates, flame retardants, per- and polyfluoroalkyl substances (PFAS), dioxins, UV-stabilizers, and toxic metals such as lead and cadmium. These chemicals are used extensively in everyday products such as packaging, construction materials, cookware, children's toys, and cosmetics.
The dramatic increase in plastic manufacturing has led to a significant environmental impact from microplastics, with plastic waste affecting thousands of species in the aquatic environment. As plastic degrades, microplastics enter the terrestrial ecosystem, and their bioaccumulation poses an accelerating risk to mammals and human health.

Salt is essential for human physiological function
However, it is important to note that while salt is necessary for the body, excessive sodium intake is a global concern and can lead to detrimental health effects. Excess sodium is a risk factor for hypertension or high blood pressure, which increases the risk of heart failure. Consuming too little salt can also be harmful, leading to hyponatremia, with symptoms such as dizziness, confusion, muscle twitches, and seizures.
Salt is prevalent in many foods and is added as a seasoning. It is also used in food preservation due to its ability to prevent bacterial growth. Different types of salt include table salt, Himalayan pink salt, sea salt, rock salt, kosher salt, and more.
Regarding the presence of plastic in Himalayan salt, studies have shown that Himalayan rock salt, extracted through mining, has observed an increase in microplastic contamination. This contamination is likely due to the addition of airborne microplastics during the processing and packaging of the salt. However, compared to sea salt, Himalayan salt is supposedly protected from environmental contaminants due to its extraction method. One study found that 90% of sea salt tested contained microplastics, which is attributed to the rise of plastic pollutants in the oceans. Therefore, while Himalayan salt may have some microplastic contamination, it is likely to be less contaminated compared to sea salt.

Frequently asked questions
Himalayan salt is extracted through mining, which means it is less exposed to environmental contaminants like plastic pollution. However, there is still a risk of microplastic contamination during the processing and packaging of the salt. Some studies have detected microplastics in Himalayan salt samples, but the level of contamination is generally lower than in sea salt.
Plastic pollution in the ocean is a significant issue, with about 8 million tons of plastic entering marine environments each year. Sea salt is derived from evaporated seawater, so it can contain microplastics. Plastic particles can also be introduced during the industrial processing and packaging of salt.
Himalayan salt is considered a more natural product than table salt because it is minimally processed and extracted by hand. It does not contain additives, chemicals, or anti-caking agents found in some table salts. However, it is important to note that the pink hue of Himalayan salt comes from heavy metal impurities, specifically iron.
