The nutritional value of sea salt and table salt are about the same as they are both primarily sodium chloride. [15] [16] Table salt is more processed than sea salt to eliminate minerals and usually contains an additive such as silicon dioxide to prevent clumping. [15] Iodine, an element essential for human health, [17] is present only in small ...
A 2015 review of 15 brands of table salts commercially available in China found microplastics were much more prevalent in sea salts compared to lake, rock, or well salts, attributing this to sea salts being contaminated by ocean water pollution while the rock/well salts were more likely contaminated during the production stages of collecting ...
Salt sourced from India ranged from 115 to 560 particles/kg. [37] Sea salt sourced from China reported more than 400/kg. [38] Microplastics also accrue in shellfish grown or harvested in regions with microplastic contamination of seawater, and are a significant contributor to human exposure. [39]
Even salt can be a site of microplastic exposure. A 2022 study found that coarse himalayan pink salt had the highest concentrations of microplastics, followed by black salt and rock salt.
Unrefined sea salt is minimally processed, retaining trace minerals that might lend color or flavor to the salt. (Refined sea salt, though, has been washed to remove minerals and contaminants, so ...
Edible salts, also known as table salts, are salts generally derived from mining or evaporation (including sea salt).Edible salts may be identified by such characteristics as their geographic origin, method of preparation, natural impurities, additives, flavourings, or intended purpose (such as pickling or curing).
