Sodium is essential for regulating the fluid levels in the body. Along with Potassium and Chloride, it also regulated the levels of acids and bases in bodily fluids and cells, which is essential for the body to continue functioning.

The main source of sodium in most diets is from sodium chloride, also known as salt. Present in most foods and beverages, it is 39% sodium. Processed foods generally have higher levels of sodium. Most people only need about 500mg a day of sodium, yet they consume over 2,500mg.

Too much sodium causes:

• High blood pressure, raising the risk of heart disease, kidney disease, and stroke
• Water and Potassium to be depleted from cells

On the other hand, not enough sodium causes:

• Muscle Cramps
• Weakness
• Nausea
• Diarrhea

Tips for avoiding sodium in your diet:

• Don't add salt at the table - your craving for salt will go away if you let it!
• Gradually remove salt from foods you cook.
• Pick up a low-sodium cookbook. Several are available, and shouldn't be hard to track down.
• Stay away from processed foods; they tend to use sodium as a flavoring agent.
• Stay away from fast-food restaurants; salt and fast-food go hand in hand.
