What is soy sauce?

This condiment is common in many types of Asian cuisine. It originated in China over 2,000 years ago, spreading throughout Asia and eventually the rest of the world.

It is used to introduce or add a salty or umami flavor to dishes. Some sweet varieties also exist, but the umami flavor is a favorite everywhere.

There are hundreds of different types, but the light kind is the most popular in the West.

The sauce is made by fermenting soybeans and wheat in water. There are two main methods of fermentation used: the traditional way and the chemical way.

In the traditional way, the soybeans and wheat are left to ferment on their own for months or even years. For the chemical way, the fermentation is quickened using heat and acids.

Can you eat soy sauce on keto?

The short answer is yes. However, there are other factors to think about like the amount, brand, type, and so on.

To be safe, always check the number of carbs on the label to be sure.

The debate around soy sauce on keto does not end with carbs, however. Some people prefer to avoid it for other reasons.

First, soy has very high sodium levels. 1 tablespoon of the sauce contributes nearly 40% of your daily sodium limit.

Secondly, people who are taking hormone replacement therapy or have been diagnosed with hormonal cancer may be advised to limit their consumption of soy products. Speak with your doctor if this may affect you.

Lastly, most of the soy used to make this product is GMO. Over 90% in the United States is GMO and the situation is not that different in other countries.

Scientists have not found any side effects of eating GMO crops, but some people would rather avoid them.

 

How much soy sauce can you eat on keto?

With every tablespoon having less than a gram of carbs, you can have up to 3 tablespoons a day. If you have done the math, that is only 2.1 g of net carbs, so you might be wondering, why stop there?

First, we’re talking about a condiment. It is very likely that you are eating it with other foods that contain carbs. If you use up your carb allowance on a condiment, then how much nutritious food can you have?

Secondly, it has a very high sodium content. Three tablespoons are enough to cross your daily sodium limit. High sodium consumption is related to a high risk for high blood pressure and other heart and kidney complications.

The good news is that research shows that the consumption of soy products does not increase one’s risk for heart disease. Still, it doesn’t hurt to stay cautious.

 

What soy sauce should you have on keto?

The types available across the world are endless. However, these are the most common in most countries:

  • Light. This is the most popular with only 0.7 g of net carbs per tablespoon.
  • Dark. This is rarely keto-friendly as most brands add brown sugar and molasses to enrich the flavor and color of the product.
  • Tamari. This is usually made without wheat, making it gluten-free. It is also low in carbs and therefore keto-friendly.
  • Sweet. This is the furthest from keto-friendliness as sugar is added to give it a sweet flavor.
  • Low-sodium. This type is similar to light except that it has less sodium. It is therefore just as keto-friendly.

Remember, some brands may carry keto-friendly versions but add carbs to them. Always read the nutrition label before buying an unfamiliar brand.
