Can Babies Have Soy Sauce?


Soy sauce is a common condiment found in many Asian cuisines.

It adds a salty, umami flavor to various dishes.

But when it comes to babies, the question arises: is it safe for them to consume?

Quick Answer

The answer isn’t a simple yes or no. While occasional exposure to small amounts of soy sauce isn’t harmful, regular consumption isn’t recommended for babies under 12 months old.

Reasons to Avoid Soy Sauce for Babies

There are three primary reasons why soy sauce isn’t recommended for babies:

1. High Sodium Content:

The main concern with soy sauce is its high sodium content.

According to the American Academy of Pediatrics (AAP), babies should not have more than 1 gram of sodium per day.

This is because their kidneys are still developing and cannot process large amounts of sodium.

Too much sodium can lead to high blood pressure, kidney problems, and other health problems later in life.

2. Potential Allergens:

Soy sauce typically contains soy and wheat, which are common allergens for babies.

Introducing these allergens too early can increase the risk of developing allergies.

3. Unsuitable Flavor for Baby’s Taste Buds:

Babies’ taste buds are still developing.

The strong salty and umami flavors of soy sauce can be overwhelming and may discourage them from trying other foods.

Excess sodium intake can put a strain on a baby’s developing kidneys and contribute to high blood pressure later in life. It can also lead to dehydration and other health problems.

The Sodium Content in Different Types of Soy Sauce

Here’s a breakdown of the sodium content in different types of soy sauce:

  • Regular soy sauce: 1 tablespoon (15 ml) contains about 900mg of sodium.
  • Light soy sauce: 1 tablespoon (15 ml) contains about 500mg of sodium.
  • Reduced-sodium soy sauce: 1 tablespoon (15 ml) contains about 250mg of sodium.

Alternatives to Soy Sauce for Babies

Several safe and delicious alternatives can offer similar savory flavors without the high sodium content and potential allergens of soy sauce:

1. Coconut aminos:

This naturally sweet and savory sauce is derived from coconut nectar and offers a comparable flavor profile to soy sauce with significantly less sodium.

2. Nutritional yeast:

This deactivated yeast provides a cheesy and umami flavor boost with added nutrients like B vitamins and protein.

3. Herbs and spices:

Herbs like parsley, basil, and dill, and spices like garlic powder and paprika, can add delicious flavor and complexity to your baby’s food without sodium concerns.

4. Bone broth:

Homemade bone broth is a rich source of minerals and adds a subtle savory flavor to your baby’s food.

Tips for Introducing Soy Sauce to Babies

However, even after 1 year old, it’s still important to limit your baby’s intake of soy sauce. You can do this by:

  • Start by offering a very small amount, diluted with water or breastmilk.
  • Monitor your baby for any allergic reactions.
  • Be mindful of the overall sodium intake throughout the day.
  • Choose low-sodium soy sauce options whenever possible.


While soy sauce is not inherently harmful to babies, its high sodium content makes it unsuitable for them until they are closer to 12 months old.
