Himalayan pink salt is sourced from ancient mineral deposits
The salt deposits were formed when a shallow salty sea that once covered the area gradually evaporated due to high temperatures and low rainfall. This left behind layers of salt and other sediments, which were subsequently covered by sedimentary rocks through tectonic activity. The salt deposits were first discovered about 2000 years ago by Alexander the Great, but they were not mined until much later when the Moghul emperor Akbar the Great reopened a deposit, creating the Khewra Salt Mine.
The Khewra Salt Mine is the largest and oldest salt mine in Pakistan and produces 385,000 tons of salt per year. The salt is mined using a "room and pillar" method, where large chambers are excavated around the salt deposit while leaving enough pillars of salt to support the mine. The mined salt is then hauled to workshops, where it is broken down and mechanically ground to the desired crystal grain size.
Himalayan pink salt has gained popularity due to its flavour and purported health benefits. It is claimed to have higher concentrations of essential minerals such as calcium, iron, potassium, and magnesium compared to ordinary table salt. However, it is important to note that these mineral levels may not be high enough to provide significant health benefits without excessive intake, which could lead to elevated sodium consumption.
While Himalayan pink salt is marketed as a pure and natural alternative to regular salt, some concerns have been raised about potential contamination with heavy metals and microplastics. The presence of heavy metals in the salt may be due to the naturally occurring metals in the soil of the region, which has higher levels of cadmium. However, it is worth noting that the salt's mineral content reflects the ancient environment in which it was formed.

It is marketed as a pure alternative to regular salt
Himalayan pink salt has become increasingly popular in recent years, with exports of the salt growing to 400,000 tons each year. It is marketed as a pure alternative to regular salt, free of additives and chemicals, and is thought to be much more natural.
Regular table salt is a highly refined product with added chemicals. It is often bleached and loaded with anti-caking agents and other additives to make it flow more easily. To make it completely white, small amounts of sugar are also added to prevent the iodine from oxidising. These anti-caking agents often contain aluminium, which has been linked to Alzheimer's disease.
Himalayan pink salt, on the other hand, is mined by hand from the Khewra Salt Mine in Pakistan and is minimally processed. It is believed to have been formed millions of years ago from the evaporation of ancient bodies of water. This ancient origin is also the reason for its metal content, as it reflects the environment of that time.
However, it is important to note that Himalayan pink salt does contain sodium chloride, just like regular salt. While it has slightly lower sodium levels and a small amount of additional minerals, the difference in nutritional content is negligible. Research has not shown that Himalayan salt has any unique health benefits compared to other dietary salt.
Therefore, while Himalayan pink salt may be a pure alternative to regular salt in terms of additives and processing, it is important to remember that salt is salt, and excessive consumption of any kind can contribute to health issues.

Studies have found microplastics in Himalayan pink salt
Himalayan pink salt is often marketed as a pure alternative to regular table salt, which typically contains additives and anti-caking agents. It is mined from ancient salt beds that were formed long before plastic was invented. However, studies have found microplastics in Himalayan pink salt, raising concerns about the extent of plastic pollution in our environment and its potential impact on human health.
One study, published in the Journal of Environmental Science & Pollution in 2022, analyzed common Australian commercial salts, including fine and coarse Himalayan pink salt. Surprisingly, the study found higher levels of microplastic contamination in terrestrial salts, such as Himalayan pink salt, compared to marine salts. The highest levels of microplastics were found in coarse Himalayan salt. The study suggests that the contamination in mined salts may have originated from manufacturing, packaging, atmospheric, or storage processes.
Another study, published in the journal Environmental Science & Technology in 2018, estimated that an average adult ingests approximately 2,000 microplastics per year through salt consumption. This is mainly due to the high presence of microplastics in the world's oceans and waterways, as sea salt has also been found to be contaminated with microplastics. A global study in 2019 found that 94% of tested salt products contained microplastics, with the most common types being polyethylene terephthalate (PET), polypropylene (PP), and polyethylene (PE).
The presence of microplastics in Himalayan pink salt highlights the pervasive nature of plastic pollution and its ability to infiltrate even seemingly untouched natural products. While the health impacts of ingesting microplastics are not yet fully understood, plastics do contain known carcinogens. Consumers concerned about microplastic contamination in their salt can look for brands that harvest salt from cleaner, less polluted environments and seek out companies that provide "microplastic-free" labels or transparency in their sourcing and testing processes.

Microplastics may enter salt during manufacturing, packaging, or storage
Microplastics may enter salt during the manufacturing process. It is believed that sea salt is more vulnerable to plastic contamination because of how it is made, through a process of dehydration of seawater. Plastic waste enters the ocean and, due to the low density of some plastics, they float on the water's surface and are readily directed into saltpans.
Microplastics may also enter salt during the packaging process. A study found that a few isolated particles from the salt samples had a similar composition to their packaging. The study rejected the hypothesis that the packaging material degraded and contaminated the salt product, as the fragments were highly corroded, indicating their long-term presence in the environment.
Microplastics may also enter salt during the storage process. As plastic pollution is pervasive in the environment, salt may be contaminated during storage if it is exposed to the environment.

Consumers can look for brands that test for and certify microplastic-free salt
Consumers concerned about the presence of microplastics in their salt can take proactive steps to ensure they are buying microplastic-free products. While it is challenging to avoid microplastics entirely, consumers can reduce their exposure by choosing brands that prioritise plastic-free production and packaging.
One way to identify these brands is to look for third-party lab testing and certification. Some companies now test their salt for microplastic contamination and provide certification. Consumers can look for "microplastic-free" labels or check the company's transparency regarding their sourcing and testing processes. For example, Vera Salt, sourced from an ancient spring in Spain, provides third-party lab testing for microplastics and offers 100% plastic-free packaging.
Additionally, consumers can opt for salts harvested from cleaner, less polluted environments. Himalayan pink salt and some deep-mined salts often have lower microplastic contamination due to their terrestrial origins. Redmond Real Salt from Utah is another example of a salt similar to Himalayan salt in purity and taste.
By supporting brands that prioritise microplastic-free production and packaging, consumers can contribute to a cleaner food chain and take a proactive step toward better health. While the long-term effects of ingesting microplastics are still being studied, early findings suggest potential health risks, including the accumulation of harmful chemicals and toxins in the body.
