What is Fish Sauce?

Fish sauce, also known as nam pla in Thai and nuoc mam in Vietnamese, is a condiment used in Southeast Asian cuisine. It is generally made from fermented fish or shellfish that has been combined with salt.

Fish sauce has a uniquely pungent aroma and salty taste, which makes it an essential ingredient in dishes such as stir-fries, marinades, and dipping sauces. Due to its umami-rich flavor profile, many chefs consider fish sauce to be the “secret ingredient” that adds depth and complexity to their dishes.

The History of Fish Sauce

The origins of fish sauce can be traced back over 2000 years to ancient Rome, where a similar condiment known as garum was popular among the aristocracy. However, it wasn’t until traders from China introduced the concept to Vietnam around 200 AD that fish sauce began to take on its distinct Southeast Asian identity.

Over time, different variations of the condiment developed across the region, with countries like Thailand, the Philippines, and Cambodia all creating their own unique blends.

How is Fish Sauce Made?

The process for making fish sauce varies depending on the specific recipe, but the basic steps remain the same:

  • The primary ingredient (usually fish or shellfish) is mixed with salt and left to ferment in barrels or vats.
  • As the mixture ferments, enzymes break down the proteins and fats in the fish or shellfish, resulting in a liquid often referred to as “fish juice.”
  • The fish juice is drained off, strained, and usually left to mature for several months.
  • The result is a dark, viscous liquid with a strong, salty flavor.

One common misconception about fish sauce is that it contains gluten. However, as long as the brand you’re using is made solely with fish and salt (as most traditional versions are), it should be completely safe for those with celiac disease or a gluten sensitivity.

“The National Celiac Association confirms that fish sauce does not contain any wheat protein, and thus is safe to consume by individuals avoiding gluten in their diet.” – National Celiac Association

In fact, many brands of fish sauce proudly proclaim themselves to be gluten-free on their packaging, so be sure to check labels carefully if you have concerns.

It’s worth noting, however, that some modern variations of fish sauce may include additional ingredients like sugar, vinegar, or hydrolyzed vegetable protein (HVP). In these cases, it’s possible that gluten could be present, so it’s important to read ingredient lists thoroughly before purchasing.

If you’re sensitive to gluten or simply looking to reduce your overall intake, there are also low-sodium and reduced-sugar options available that can be used in place of standard fish sauce.

While the exact recipe for fish sauce may vary from culture to culture and kitchen to kitchen, it remains an essential ingredient in Southeast Asian cooking—even for those following a gluten-free lifestyle.

What are the Ingredients in Fish Sauce?

Fish sauce is a staple ingredient of several Southeast Asian cuisines and has been in use for thousands of years. While it is an incredibly flavorful condiment that can elevate any dish, those who have gluten intolerance or coeliac disease may need to be cautious about its usage since some brands might contain gluten.


The primary component of fish sauce comes from fish that are sourced from Asia’s coastal regions – usually anchovy, mackerel, or herring. The fish flesh and bones are ground up into small pieces and left to ferment with salt for weeks, during which time the fish enzymes work their magic on the ingredients’ proteins to create the savory umami taste that characterizes fish sauce.

“Fish sauce has become so ubiquitous in our cooking today that we don’t think twice about adding it to Caesar dressing or pasta sauce.”- David Chang


Salt plays a crucial role in the production process as it helps preserve the fish while also contributing to the fermentation process. In traditional methods, sea salt was used, but iodized salt is more commonly utilized today due to its accessibility and affordability. The amount of salt utilized can vary between different producers, depending on their recipe and intended flavor profile.


While not always included in every variety, water can be added in some instances to dilute the strong fish aroma and flavor. Additionally, the addition of water makes the sauce easier to pour and measure, making it more commercially viable. Some premium quality brands eschew this practice altogether and sell undiluted fish sauce brimming with rich, complex flavors.

When trying to determine whether or not your favorite brand of fish sauce is safe for coeliacs or those with gluten intolerance, the most important thing to do is read the label closely. Some brands might add wheat, oats, barley, or other cereals as thickeners or flavor enhancers, so always scrutinize the ingredients list thoroughly. Alternatively, look for a certified gluten-free product explicitly labeled on the bottle.

Thankfully, several fish sauce manufacturers have recognized that offering gluten-free products is beneficial not only for the health-conscious but also for appealing to a broader range of customers.

“If there is magic on this planet, it is contained in water.” – Loren Eiseley

Is Gluten Commonly Found in Fish Sauce?

Fish sauce is a condiment that has been used for centuries, especially in Southeast Asia. It is made from fermented fish and salt, and it adds flavor to many dishes like stir-fries, marinades, noodles, soups, and dipping sauces.

If you have celiac disease or gluten intolerance, you might be wondering if fish sauce contains gluten. The short answer is that some fish sauces may contain gluten, and others don’t. Let’s dive deeper into the details.

Why Gluten is Found in Some Fish Sauces

Gluten is a type of protein found in wheat, barley, rye, and related grains. It can cause an immune reaction in people with celiac disease or non-celiac gluten sensitivity. Therefore, they must avoid all sources of gluten in their diet, including hidden ones.

Some fish sauces may contain gluten because they use wheat or soy sauce as an ingredient or a stabilizer. Wheat-based soy sauce is a common ingredient in Chinese-style fish sauce, while Japanese-style fish sauce uses soy sauce made from soybeans and usually doesn’t contain wheat. Additionally, some manufacturers add thickeners, fillers, or flavor enhancers that contain gluten, such as hydrolyzed wheat protein or modified food starch.

The good news is that many fish sauce brands nowadays are aware of the demand for gluten-free products and offer options that do not contain any gluten ingredients. You just need to look at the label carefully or contact the manufacturer for more information.

How to Identify Gluten in Fish Sauce

To find out if a particular fish sauce brand contains gluten, you should check the list of ingredients on the label. Look for words that indicate the presence of wheat, barley, rye, or soy sauce:

  • Wheat
  • Barley
  • Rye
  • Soy sauce (if made with wheat)
  • Hydrolyzed wheat protein
  • Modified food starch (if derived from wheat)

If you are unsure whether a certain ingredient is gluten-free or not, you can use online resources to verify it, such as the Celiac Disease Foundation’s Gluten-Free Product Certification Program. You can also contact the manufacturer directly and ask them about their testing procedures for gluten or cross-contamination.

Gluten-Free Fish Sauce Alternatives

If your favorite fish sauce brand contains gluten or if you prefer to avoid gluten altogether, there are plenty of gluten-free fish sauce alternatives that you can try:

  • Red Boat Fish Sauce: This brand uses only black anchovy and sea salt in its fermentation process, without any added ingredients like sugar or MSG.
  • Aloha Shoyu Gluten-Free Fish Sauce: This brand uses soybeans instead of wheat to make its soy sauce, and it doesn’t include any artificial flavors or preservatives.
  • Tamari or Coconut Aminos: These are soy sauce substitutes made from fermented soybeans or coconut sap, respectively. They have a similar umami flavor and can be used in place of fish sauce in many recipes.
“Fish sauce is essentially liquid umami.” – Andrea Nguyen, Author of “The Pho Cookbook”

Some fish sauces may contain gluten, but many gluten-free options are available on the market. By checking the labels and doing your research, you can enjoy the delicious flavor of fish sauce in your gluten-free diet.

What Brands of Fish Sauce are Gluten Free?

However, those with gluten sensitivities or celiac disease need to ensure that the fish sauce they consume is gluten-free. Luckily, there are several brands of gluten-free fish sauce available on the market.

Despite its name, three crab extracts aren’t actually used in this brand’s recipe—but based on the taste you’d never know it. Their fish sauce is gluten-free, made with anchovies, water, salt, and sugar. It’s also baby-friendly as they’ve received a certification from the European Union for safe levels of free glutamates (a type of amino acid often found in condiments).

How to Check if Your Fish Sauce is Gluten Free?

Fish sauce is a popular condiment in Southeast Asian cuisine that adds a unique umami flavor to dishes. But for those with gluten sensitivity or celiac disease, it’s crucial to ensure that the fish sauce they use is gluten-free. Here are some ways to check if your fish sauce is safe to consume:

Reading Labels for Gluten-Free Certification

The easiest and most reliable way to know if your fish sauce is gluten-free is by checking the label for a “certified gluten-free” logo. If the product has been certified by organizations such as the Gluten-Free Certification Organization (GFCO) or the Celiac Support Association (CSA), you can be assured that it contains less than 20 ppm of gluten, which is considered safe for people with celiac disease.

If the bottle doesn’t have a gluten-free certification, look for ingredients that typically contain gluten, such as wheat, barley, or rye. Some cheaper brands might use wheat or soy sauce as fillers, so make sure to read the labels carefully.

Testing Fish Sauce for Gluten

If you’re unsure about the gluten content of your fish sauce even after reading the label, there are simple tests to see if it contains gluten. The most common test involves using a gluten testing kit, also known as an enzyme-linked immunosorbent assay (ELISA) test kit, which detects even small amounts of gluten in food products. The testing kits usually come with test strips or plates where you mix the sample food and a solution containing antibodies that bind specifically to gluten molecules. After a set amount of time, the color on the strip or plate indicates whether or not the sample contains more than 20 ppm of gluten.

You can purchase gluten testing kits online or at health food stores. Keep in mind that the kits can be pricey, and some people might prefer to simply opt for certified gluten-free products instead.

Another way to test fish sauce for gluten is by conducting a homemade test using vinegar and baking soda. While not as reliable as an ELISA test kit, it’s still a useful method for detecting large amounts of gluten. Here are the steps:

  • Pour 1 teaspoon of fish sauce into a small bowl
  • Add 1 tablespoon of distilled white vinegar and mix well
  • In a separate bowl, put 1/4 teaspoon of baking soda
  • Add a few drops of water to make a paste
  • Mix the fish sauce mixture with the baking soda paste
  • If it fizzes up, it could indicate the presence of gluten. If it stays flat, it’s likely gluten-free.

Keep in mind that this method isn’t foolproof, and larger amounts of gluten could slip through undetected. It’s always best to rely on certified gluten-free products whenever possible.

“As someone who has celiac disease, I’ve learned to read labels carefully and do my research before consuming any new foods or condiments.” -Jackie A. from Verywell Health

While browsing through your local store’s shelves looking for the right fish sauce, just remember to check for the “certified gluten-free” logo and familiarize yourself with ingredients that typically contain gluten. In addition, you have alternative options like conducting gluten tests if you need further assurance about product safety. With these precautions, you’ll keep safe from gluten exposure, helping you enjoy your favorite dishes without worry!
