Is Mustard Keto?

When following a ketogenic diet, it is essential to carefully consider the ingredients of the foods you consume. Mustard, a popular condiment, is often used to add flavor to various dishes. But is mustard keto-friendly? Let’s delve into the nutritional profile of mustard and explore whether it fits into a ketogenic lifestyle.

The Basics of the Ketogenic Diet

The ketogenic diet is a low-carb, high-fat diet that aims to put the body into a state of ketosis. In this metabolic state, the body primarily burns fat for fuel instead of carbohydrates. To achieve and maintain ketosis, it is crucial to limit carbohydrate intake to a minimum while increasing fat consumption.

The Nutritional Profile of Mustard

Mustard is made from mustard seeds, vinegar, water, and various spices. It is typically low in calories and carbohydrates, making it a potentially suitable condiment for those following a ketogenic diet. However, it is important to note that different types of mustard may have slightly different nutritional profiles.

Here is a general overview of the nutritional content of one tablespoon (14 grams) of yellow mustard:

  • Calories: 3
  • Protein: 0.2 grams
  • Fat: 0.2 grams
  • Carbohydrates: 0.6 grams
  • Fiber: 0.3 grams

As we can see, mustard is extremely low in calories, fat, and carbohydrates. The small amount of carbohydrates it contains is primarily from fiber, which is not fully digested by the body and does not significantly impact blood sugar levels. Therefore, mustard can be considered a keto-friendly condiment.

Health Benefits of Mustard

In addition to being low in carbohydrates, mustard also offers several health benefits:

  • Rich in Antioxidants: Mustard seeds contain antioxidants, such as selenium and omega-3 fatty acids, which help protect the body against oxidative stress and inflammation.
  • Potential Cancer-Fighting Properties: Some studies suggest that the compounds found in mustard seeds may have anti-cancer effects, particularly against gastrointestinal and colorectal cancers.
  • May Aid Digestion: Mustard seeds are known to stimulate the production of digestive juices, which can improve digestion and alleviate symptoms such as bloating and indigestion.
  • Source of Minerals: Mustard seeds are a good source of minerals like magnesium, phosphorus, and calcium, which are essential for maintaining healthy bones and teeth.

Using Mustard on a Keto Diet

Mustard can be a versatile and flavorful addition to your keto meals. Here are some ideas on how to incorporate mustard into your ketogenic diet:

  • Use mustard as a dipping sauce for low-carb snacks like celery sticks or cucumber slices.
  • Add mustard to homemade salad dressings to enhance the flavor without adding unnecessary carbohydrates.
  • Spread mustard on lettuce wraps or low-carb bread to add a tangy kick to your sandwiches.
  • Marinate meats in a mixture of mustard, herbs, and spices before grilling or baking for added flavor.


Mustard is generally considered keto-friendly due to its low carbohydrate content. It can be enjoyed in moderation as a condiment or ingredient in various keto dishes. However, it is always important to check the labels of store-bought mustard products, as some may contain added sugars or other ingredients that could increase the carbohydrate content. As with any food, it is best to consume mustard in moderation as part of a well-rounded ketogenic diet.
