While salt (sodium chloride) itself is not typically considered an allergen, recent research suggests it might play a role in triggering allergic reactions. Scientists have discovered that sodium chloride can promote the production of Th2 cells, a type of immune cell associated with allergic responses. These cells are responsible for releasing substances that contribute to symptoms like inflammation, itching, and sneezing.
However, it's crucial to understand that salt itself doesn't directly cause allergies. Instead, it acts as a trigger, potentially making people more susceptible to developing allergic reactions.
It's important to note that allergies to sea salt are extremely rare, but they are possible. Some individuals may react to trace minerals or impurities present in sea salt, not the salt itself.
