Is Sauerkraut a Low Carb Food?
Sauerkraut is a sour fermented cabbage dish that has been popular in Europe for centuries. It continues to grow in popularity globally thanks to its tangy, salty flavor and numerous health benefits. But is sauerkraut low in carbs? Let's take a closer look.
What is Sauerkraut?
Sauerkraut is made by finely shredding cabbage and layering it with salt before allowing it to ferment. The natural lactic acid bacteria on the cabbage breaks down the sugars into lactic acid, giving sauerkraut its distinctive sour flavor. The fermentation process also results in natural probiotics, making sauerkraut a nutritious gut-healthy food.
Traditional sauerkraut contains just two ingredients - cabbage and salt. Some modern commercial varieties may contain additional ingredients like spices, herbs, and preservatives. For the purposes of this article, we will focus on traditional sauerkraut made from only cabbage and salt.

Potential Concerns

Overall, sauerkraut is well tolerated by most people eating a low carb diet. But pay attention to how your body responds and cut back if you experience any persistent digestive distress.
Low Sodium Sauerkraut Options
If you need to limit sodium, you can look for reduced sodium or no salt added varieties of sauerkraut. You can also give homemade sauerkraut a try using less salt in the initial brine.
Rinsing canned or jarred sauerkraut before eating can also help wash away some of the excess sodium. Just be sure to thoroughly pat it dry so it doesn't get too watered down.
