Did you know that sodium has multiple secret identities and they’re hidden right under your nose? Sodium can be hidden in food in the form of preservatives. While a food may be labeled as “No/Low Salt, “Salt Free,” or “Low Sodium,” it does not mean that it is sodium free. Let’s uncover sodium’s secret identities.
Sodium as Preservatives
When looking at an ingredient list, you may not always see just “salt” or “sodium” listed on the ingredients. This is because it is usually hidden in the form of a preservative or sodium compound. Listed below are common sodium identities:
- Monosodium Glutamate (MSG)
- Sodium Benzoate
- Sodium Nitrite/Nitrate
- Sodium Carbonate
- Sodium Phosphate
- Disodium ethylenediaminetetraacetic acid (EDTA)

Sodium Replacements
Some products are labeled as “Salt/Sodium Free,” but still taste salty. Why is that? Great question! Companies can replace sodium chloride with potassium chloride which generally has a salty taste as well. This, however, may be equally as dangerous for those with kidney diseases. Just as sodium does, potassium helps your body to maintain mineral and fluid balances. Eating too much potassium can affect fluid balance, muscle function, and other cause other side effects or symptoms. It is important to be mindful of what your sodium may have been replaced with. When in doubt, opt for using only herbs and spices when cooking and be sure to check your food labels.
Misleading Advertising
When a food product is labeled as “No Salt/Sodium Added” it does not necessarily mean that the food is free of sodium. Many food products are made by one producer, relabeled, and sold by another. This means that by the time it gets to the second company, if nothing is done to it, they can claim that there was no salt or sodium added BY THEM. This can be incredibly misleading. This is why it is important to read the nutrition label closely and understand what your sodium limit is.
When grocery shopping, always be sure to check your food labels and ingredients lists. You never know what may be hiding within them! As always, stay safe and healthy!
