Tamari vs soy sauce: the differences
What’s the difference between these salty sauces? Here’s a breakdown:
- First, what is soy sauce? Soy sauce is a common ingredient in Asian cooking and beyond: it’s salty and contains loads of umami (savory flavor). It’s Chinese in origin and made from a fermented paste of soybeans and grains. It’s widely used many cuisines to add a salty, savory component to sauces, marinades, stir fries, and more.
- What is tamari? Tamari is a Japanese variety of soy sauce that’s made as the bi-product of making miso paste. The biggest difference between soy sauce vs tamari is that tamari contains little to no wheat! Many brands of tamari are a gluten-free substitute for soy sauce. Tamari has a slightly richer, more savory flavor than soy sauce, which can be slightly sweet from the wheat.
You can substitute one for the other
Soy sauce and tamari work as substitutes for each other! Here’s what to know about using them in recipes:
- Tamari has a richer flavor than soy sauce. It can taste slightly less salty, but it really depends on the brand. In a back to back taste test brands from our refrigerator, we found the two tasted very similar. When you use tamari as a gluten free soy sauce substitute, you may want to add a bit more or a pinch or two of kosher salt: but you should do it to taste.
- Soy sauce has a more straightforward salty flavor. Use it as a tamari substitute if you don’t eat exclusively gluten-free.
Tamari vs soy sauce: which is healthier?
Because tamari is gluten-free, does that make it healthier than soy sauce? Not necessarily. Here’s the main breakdown:
- Tamari and soy sauce have essentially the same sodium level. Tamari has 980 mg per tablespoon (source) and soy sauce has 902 mg sodium per tablespoon (source). Both are meant to be consumed in moderation as a seasoning: they are not considered as stand-alone health foods.
- Tamari may contain less additives. Many brands of soy sauce can contain MSG. So if eating all natural is important to you, you may want to opt for tamari.
Bottom line: You can enjoy both tamari and soy sauce moderation as part of a healthy diet.

Okay-I love your recipes! My husband discovered he’s a Type 2 Diabetic two years ago, and dove into MasteringDiabetes.org Oddly, it has actually worked for him. (After years of at least thirty different diets that never worked.) He has lost ALL his excess weight, and is no longer obese or even overweight! He is also no longer Diabetic, as his numbers are perfect, but he must monitor his glucose levels and numbers to remain that way, so he follows their program religiously-a half hour on his stationary bike (he’s finished eight thick books on that bike) and intermittent fasting in addition to ALWAYS eating only MD compliant food.
There are so many people who have insulin resistance, and could solve 90% of their aches, pains, and weight by following that plan, just using their free recipes. Since you seem to really care about health, could you please look into it, and begin to develop EASY Mastering Diabetes compliant recipes? You could save the USA from sinking under the weight of everyone who buys grocery store processed food so full of preservatives, pesticides and poisons, we are all dying.
My husband and I spend six months per year living in Europe, helping our daughter with her oldest, who was born in the USA and is on the autism spectrum. Europe won’t even sell packages that pass as “food” here. (The only thing I can buy in an American cereal section is puffed rice and whole grains that haven’t been messed with by our food industry, yet people here buy that garbage for their CHILDREN!!!) We always come back healthier when we eat in Europe. Too bad we can only get six month visas each year. We go as often as our daughter can send us plane tickets.
Inflammation is an enemy to us all, and we don’t need to suffer with anything inflammatory as long as we learn to eat right.
