Understanding Soy Sauce

Traditional soy sauce is a common ingredient in various dishes, from your favorite sushi roll at Japanese restaurants to stir-fries in Chinese restaurants. It is produced through a fermentation process that utilizes soya beans, wheat, and a mold known as Aspergillus. The result is a savory flavor and a rich umami taste that's a hallmark of most Asian cuisines.

The most common type of soy sauce, light Chinese soy sauce, has a milder, sweeter taste compared to the more intense Japanese dark soy sauce. Regardless of type, the nutritional information of soy sauces may vary between brands, with serving sizes usually calculated per tablespoon of soy sauce.

Carb Content of Soy Sauce 

Now to the burning question, "Is soy sauce keto friendly?" Here's where we get into the nitty-gritty. Regular soy sauce contains approximately 1 gram of carbs per tablespoon serving. That's not a lot, but if you're on a strict ketogenic diet, every gram of carbs counts toward your daily carb intake.

While a small amount of soy sauce may not significantly affect your grams of net carbs, it's important to note that sweet soy sauce has added sugars, which increases its carb count. Therefore, it's essential to read the nutrition label when deciding which soy sauce to use. If you're practicing clean keto as opposed to dirty keto, opt for soy sauce with no added sugars.

Sodium Intake and Soy Sauce

Aside from its carb content, soy sauce has a high sodium content. A tablespoon of soy sauce contains approximately 900 mg of sodium, potentially a concern for those with high blood pressure or heart disease. However, low sodium soy sauce options are available for those who need to monitor their sodium intake.

Keto Soy Sauce Alternatives

Thankfully, for those adhering to a strict low-carb keto diet or dealing with gluten intolerance, there are several soy sauce alternatives.

  1. Tamari Sauce: Tamari soy sauce, traditionally a Japanese soy sauce variant, offers a similar taste but is usually gluten-free and contains fewer carbohydrates.
  2. Coconut Aminos: This is a sweet and salty sauce made from coconut sap. It's a keto-friendly condiment, gluten-free, and has a similar flavor profile to soy sauce. Plus, it's a great way to add some Southeast Asia flair to your keto recipes!
  3. Liquid Aminos: Made from soybeans, this gluten-free soy sauce alternative provides the same umami flavor with lower sodium content and similar carbs per serving as traditional soy sauce.
