Electrolytes: Sodium

Sodium is an essential mineral found naturally in many foods and is a key component of salt (sodium chloride). It plays a vital role in maintaining fluid balance, nerve function, and muscle contractions in the body. In food processing, sodium compounds are often added to enhance flavor and act as preservatives.

Sodium compounds are widely used in processed foods to enhance flavor, improve texture, and extend shelf life. They are commonly found in savory snacks, processed meats, canned goods, and baked products. The FDA has set a Daily Value for sodium at 2,300 mg per serving.

Sodium is essential for life, but high intake is linked to increased blood pressure in some individuals. The FDA monitors sodium levels in processed foods. The World Health Organization (WHO) recommends limiting sodium intake to reduce the risk of cardiovascular disease. While essential, excessive sodium consumption is a public health concern.
