Soy sauce made from soybeans without wheat, known as tamari, is higher in carbohydrates, containing 5.57g in a 100g serving (1).

Carbohydrates per Serving Size

Soy sauce is more often used in smaller amounts. One average serving size of soy sauce per person is 1 tbsp, equal to 16g or ½ fl oz (15ml).

One tablespoon of soy sauce contains only 0.78g of carbohydrates.

Carbohydrate Breakdown

The carbohydrate content of soy sauce consists of 84% net carbs and only 16% dietary fiber.

Sugar Breakdown

Despite the net carb content, soy sauce contains only 0.4g of sugars, namely 0.1g of sucrose and 0.3g of glucose.

Starch: 0 g
Sucrose: 0.1 g

As a result of fermentation during production, soy sauce may instead contain sugar alcohols, also known as polyols (2). Sugar alcohol is a carbohydrate that adds a sweet flavor but provides fewer calories compared to sugar.

Comparison to Other Foods

Looking at the table below, you can see how the carbohydrate content of soy sauce compares to those of other foods.

Soy Sauce glycemic index

Soy sauce, also known as shoyu or soya sauce, is made from a fermented paste of soybeans, along with wheat, salt, and a fermenting agent.

Soy sauce is low in carbohydrates, containing 5g of carbs in a 100g serving. Of these carbohydrates, nearly 1g is made up of dietary fiber,

However, as a condiment, soy sauce is used in much smaller amounts. One average serving size of soy sauce is one tablespoon or 16g, which provides only 0.8g of carbohydrates.

Due to the low level of carbohydrates and the small serving size, an exact number for the glycemic index of soy sauce has not been researched. Nevertheless, it can be considered to be low.

Research has suggested that soy foods may be an appropriate part of diets intended to improve control of blood glucose and insulin levels, as most tested soy foods demonstrated a low glycemic index (3).

Consumption of unsweetened soy foods has also been found to play a protective role against type 2 diabetes mellitus (4).

Health checks

Low in Cholesterol
 ⓘ Dietary cholesterol is not associated with an increased risk of coronary heart disease in healthy individuals. However, dietary cholesterol is common in foods that are high in harmful saturated fats.
No Trans Fats
 ⓘ Trans fat consumption increases the risk of cardiovascular disease and mortality by negatively affecting blood lipid levels.
Low in Saturated Fats
 ⓘ Saturated fat intake can raise total cholesterol and LDL (low-density lipoprotein) levels, leading to an increased risk of atherosclerosis. Dietary guidelines recommend limiting saturated fats to under 10% of calories a day.
Low in Sodium
limit break
 ⓘ Increased sodium consumption leads to elevated blood pressure.
Low in Sugars
 ⓘ While the consumption of moderate amounts of added sugars is not detrimental to health, an excessive intake can increase the risk of obesity, and therefore, diabetes.
