MSG and Salt in Filipino Gisa: Read the Label Before Seasoning the Pot

A practical evidence-based explanation of glutamate flavour, sodium and why MSG is not an automatic replacement for all salt.

In this article

Salt, soy sauce, patis and MSG do different jobs in a gisa. They all need to be counted within the final seasoning plan: MSG contributes savoury taste and sodium, while fermented sauces bring their own salt and flavour. The FDA considers added MSG generally recognised as safe; WHO guidance concerns total dietary sodium, not avoidance of one ingredient alone. The salt-and-umami guide helps separate flavour choices from simply adding more salty products. Source 1 Source 2

Before you begin

Gather the actual labels for the salt, soy sauce, seasoning powder and MSG you use. Record sodium per labelled serving and the grams or millilitres in that serving. A compound seasoning may already contain MSG and salt. For a small taste comparison, cook one unseasoned vegetable or mushroom base and divide the finished base into two equal weighed portions; use a scale or labelled measuring spoon capable of measuring the product’s recommended dose.

The method, in order

  1. Read ingredient lists first, including compound seasonings, so the same flavouring is not added unknowingly from several products.
  2. Write each planned amount beside its label serving size. Multiply labelled sodium by the amount used divided by the labelled serving amount.
  3. Cook the vegetables and aromatics fully before the final comparison. Divide the cooked base by weight, keeping both portions at the same serving temperature.
  4. For portion A, use your recorded usual measured seasoning. For portion B, reduce one measured salty ingredient and use a small measured MSG amount within the package directions, scaled to the portion size. Record the actual changes rather than describing them as a pinch.
  5. Taste both with clean spoons under the same conditions. Note whether you prefer the savouriness, saltiness and balance. This is a home preference check, not a blind laboratory trial.
  6. Calculate sodium from all added seasonings in each portion. If B contains more sodium overall, adding MSG has not produced a sodium reduction, whatever the taste.
  7. For the next full batch, scale the preferred seasoning amounts to the amount of cooked base and taste before adding further salt. Do not assume every pot needs salt, soy sauce, patis and seasoning powder together.

Troubleshooting and choices

MSG does not mean gluten, but a soy sauce or compound powder used alongside it may contain wheat or other allergens; the food-allergy guide helps keep those checks separate. FDA-reviewed challenges have not consistently reproduced reported MSG reactions, although transient symptoms can occur in some sensitive people consuming 3 g or more without food. A diner’s reported reaction deserves attention without treating every symptom as proof of one cause. Source 1 Source 4

Portions and cost

If one labelled serving of a hypothetical soy sauce supplies 500 mg sodium and one serving of a powder supplies 400 mg, using one of each adds 900 mg to the pot. Four equal portions receive 225 mg each from those two products alone. Add any sodium from salt, MSG and other ingredients before describing the finished meal; these numbers are an example, not a brand measurement. Source 3
