What is xanthan gum?

Xanthan gum is a popular food additive that is commonly used as a thickening agent and stabilizer in a wide range of products. It is a polysaccharide, which means it is made up of multiple sugar molecules. Xanthan gum is produced through the fermentation of carbohydrates by a bacteria called Xanthomonas campestris. It was first discovered in the 1960s and has since become a staple ingredient in many processed foods.

Is xanthan gum keto-friendly?

When following a ketogenic diet, it is important to carefully consider the ingredients in the foods you consume. Xanthan gum is often used in low-carb and keto recipes as a substitute for gluten or to improve the texture of baked goods. While xanthan gum is not a significant source of carbohydrates, it does contain a small amount of sugar. However, the amount of xanthan gum typically used in recipes is so small that it contributes negligible carbs to the final product.

The nutritional profile of xanthan gum

Although xanthan gum contains a small amount of sugar, it is primarily composed of indigestible fiber. This means that it does not significantly impact blood sugar levels or insulin response. Here is the approximate nutritional profile of xanthan gum per 1 teaspoon (2 grams):

  • Calories: 7
  • Carbohydrates: 2 grams
  • Fiber: 2 grams
  • Sugar: 0 grams
  • Fat: 0 grams
  • Protein: 0 grams

Benefits of xanthan gum on a keto diet

While xanthan gum may not provide any direct nutritional benefits, it offers several advantages when following a ketogenic diet:

  • Improved texture: Xanthan gum helps create a desirable texture in low-carb baked goods, such as bread, cookies, and cakes. It adds elasticity and prevents crumbling, making it easier to achieve a similar texture to traditional high-carb recipes.
  • Increased satiety: The high fiber content of xanthan gum can help promote feelings of fullness and reduce hunger cravings. This can be particularly beneficial when following a calorie-restricted ketogenic diet for weight loss.
  • Stabilizes emulsions: Xanthan gum acts as an emulsifier, helping to stabilize mixtures of oil and water. This property is useful in keto-friendly salad dressings, sauces, and other recipes that require the combination of ingredients that would typically separate.

Considerations and potential side effects

While xanthan gum is generally considered safe for consumption, some individuals may experience digestive issues when consuming large amounts. These side effects can include bloating, gas, and diarrhea. However, the small quantities typically used in recipes are unlikely to cause any problems for most people.

It is worth noting that xanthan gum is a highly processed ingredient and may not align with the principles of a whole foods-based ketogenic diet. Some individuals prefer to avoid processed additives and opt for more natural alternatives, such as psyllium husk or ground flaxseed, which can also provide similar thickening properties.


Xanthan gum is generally considered keto-friendly due to its low carbohydrate content and minimal impact on blood sugar levels. It can be a useful ingredient for improving the texture of low-carb baked goods and stabilizing emulsions in keto-friendly recipes. However, it is important to consume xanthan gum in moderation and be mindful of any potential digestive side effects. As with any food additive, it is always best to consult with a healthcare professional or registered dietitian to determine if xanthan gum is suitable for your individual dietary needs.
