Understanding Different Types of Salt and the Role of Potassium in Low-Sodium Diets
Salt comes in various forms— rock salt, sea salt, and refined salt — differing in origin and extraction methods. Rock salt is extracted from underground salt deposits, sea salt is obtained by evaporating seawater, and refined salt is derived from mined salt or rock salt through a purification process.
While these salts primarily consist of sodium and chloride ions, they also contain trace minerals and elements. Low-sodium foods are recommended to reduce the risk of conditions like hypertension and heart disease.
Rock salt and sea salt are rich in minerals, unlike refined salt, which may lose these beneficial elements during processing. Specific sodium content varies among products, but opting for natural salt sources is generally healthier.
In addition to reducing sodium, some low-sodium foods use potassium salt as a substitute. Potassium can help control blood pressure as an alternative to sodium. However, excessive potassium intake may impact kidney function, emphasizing the need for balanced consumption.
Managing sodium intake is crucial to mitigate the risks of hypertension and heart disease. Therefore, carefully monitoring salt intake and choosing low-sodium foods, while also maintaining a balance with potassium intake, is essential for overall health.
