Nutritional Profile Overview
Whats the carb count?
Regular soy sauce contains less than 1gram of carbohydrates per tablespoon, translating to a glycemic index (GI) of about 20. In practice, thats essentially zero impact on blood sugar, making it a safe condiment from a carb perspective. According to Healthline, a tablespoon provides roughly 10calories, 0.5g carbs, and a trace amount of protein.
How much sodium am I actually eating?
Heres the sobering part: a tablespoon of traditional soy sauce packs around 870mg of sodiumroughly 38% of the recommended daily limit for most adults. Lowsodium versions drop that to about 500mg, while coconut aminos (a popular soyfree alternative) contain just 90mg. If youre watching blood pressure, those numbers matter.
Other nutrients that matter
Beyond carbs and sodium, soy sauce offers a sprinkle of isoflavonesplant compounds linked in some research to improved insulin sensitivity. A metaanalysis in the Journal of Nutrition noted modest reductions in type2 diabetes risk among regular soy eaters, although the effect is likely driven by whole soy foods rather than the condiment alone.
