A guide to Sodium

Sodium is present naturally in most foods. It can also be added to food as salt or food additives.

Sodium is a major micronutrient required by our human body. Its chief functions include:

  • Body fluid volume regulation 

  • Nerve impulse transmission

  • Muscle contraction

  • Acid-base balance maintenance.

 

While an adequate amount of sodium is essential for critical bodily functions, too much of it will lead to health issues, like hypertension and cardiovascular diseases1. It is recommended to keep sodium intake to less than 2000mg daily, which is equivalent to 1 teaspoon of salt1

 

Due to the health concerns of sodium intake, it is important to monitor and control our daily sodium intake. The nutrition information panel shows the sodium content of the foods per unit and serving sizes, and can inform consumers accordingly.
