As early as the 19th century, salt was known to have an impact on public health. In the past, it was used to cure and prevent certain diseases, such as scurvy and goiter, but today scientists are discovering even more about the benefits of sea salt. In some parts of the world, sea salt has been found to contain a variety of trace minerals, including iodine, iron, zinc, and magnesium.
Iodine is a trace mineral that is critical for human health, as it is used to regulate the production of hormones. A lack of iodine can cause goiter, fatigue, difficulty concentrating, and even thyroid disease. Additionally, iodine deficiency has been linked to cretinism or intellectual disabilities, especially in areas with a history of goiter. For these reasons, iodine is often added to table salt to ensure that people are getting enough in their diets.
In addition to providing iodine, sea salt contains other essential minerals, including iron and zinc. Iron is an important nutrient that plays an essential role in the formation of red blood cells, while zinc helps with immune system functioning, metabolism, growth, and wound healing. Sea salt is also a good source of magnesium, which is important for muscle and nerve function and helps the body to regulate blood pressure.
Sea salt can also provide minerals that can help to reduce inflammation, including potassium and sodium. These minerals play a role in controlling fluid balance in the body, while sodium helps to regulate the way nerves react to stimulation and helps to improve muscle contraction and coordination. Both potassium and sodium help to keep electrolytes in balance and are important for regulating blood pressure.
Finally, there are some additional benefits of sea salt. The minerals in sea salt can help to promote a healthy skin and hair, and can help improve the overall appearance of these areas. Additionally, the trace minerals in sea salt may be beneficial for bone health, as the minerals can help to absorb calcium and promote bone strength.
Overall, sea salt can provide a variety of important trace minerals that are essential for good health. It is important to remember, however, that sea salt should not be used in place of iodized table salt, as iodized table salt is the best source of iodine. Additionally, people who need to limit their sodium intake, such as those with certain medical conditions, should talk to a healthcare professional before adding any additional sea salt to their diet.
