Over 70% of the sodium most Americans consume comes from processed and packaged foods, not from the salt shaker. The granular, all-purpose salt found in most kitchens is known as table salt, which is a refined form of sodium chloride (NaCl). It is often enhanced with additives for pourability and fortified with iodine for health benefits.

Over 97% of the Earth's water is in its oceans, containing vast amounts of dissolved salt. The question, 'Is salt from the sea edible?' is more complex than it appears, as the method of harvesting and processing is critical to its safety and quality for human consumption.

According to a 2022 study in the *Journal of Environmental Science & Pollution*, microplastic contamination was found to be higher in some terrestrial salts, including Himalayan pink salt, compared to marine salts. This surprising finding challenges the common assumption that rock salt is a pure, uncontaminated product simply because it is mined from ancient deposits far from modern ocean pollution.

Though often perceived as a simple kitchen staple, salt comes from two major sources found deep within the earth and in its oceans. This duality in origin answers the question, "What is the primary source of salt?", revealing a fascinating geological and industrial story.

According to the Food and Drug Administration (FDA), salt is classified as a mineral and not an animal product. The question, 'Does sea salt have fish in it?' often arises due to its oceanic origin, but the answer is a clear no, as pure sea salt is a mineral compound (sodium chloride) without any animal protein.

Did you know that the world's oceans contain an estimated 4.5 million cubic miles of rock salt? The main source of common salt, also known as sodium chloride (NaCl), is the Earth's natural reserves, predominantly derived from vast quantities of seawater and ancient underground deposits.

Over 70% of the Earth's surface is covered by ocean water, from which sea salt is naturally produced. The main ingredient in sea salt, much like all other salts, is sodium chloride. However, its mineral profile and unique harvesting process set it apart from its mined counterparts.

The world's oceans contain an immense 44 x 10^15 metric tons of salt, making it the largest source of salt in the world by a monumental margin. These ancient, briny reservoirs are the ultimate origin point for virtually all the sodium chloride found on Earth.

With more than 300 million tons of salt produced globally each year, only a small fraction is designated for direct human consumption, mostly in the form of table salt. The phrase 'what salt are you table salt' refers to this highly refined version of sodium chloride (NaCl) most commonly found in shakers.

Over 90% of the world's salt production is used for industrial purposes, not for human consumption, but a small portion of a much more varied mineral is what is meant by natural salt. Natural salt refers to salt that is harvested from its source with minimal processing, allowing it to retain trace minerals that give it unique flavors, colors, and textures. Unlike highly refined table salt, which is almost pure sodium chloride, natural salts are a complex blend of minerals derived directly from nature's bounty.
