Mustard is a condiment with a tangy and spicy flavor. With almost negligible carbs, mustard makes a great addition to any keto diet. There’s more than just one type of mustard on the market however, and if you’re wondering is mustard keto friendly, it really depends on what you are buying.

Mustard provides a range of health benefits and has been a staple for thousands of years. It’s a great source of fiber, vitamin C, calcium, iron and manganese.

The only problem is, some manufacturers include ingredients not suitable for a keto diet including high fructose corn syrup, brown sugar and cane sugar. Obviously, these ingredients are not keto friendly.

The best types of mustard for keto are:

  • Yellow Mustard (Heinz and French’s are two popular brands and both keto friendly)
  • Dijon Mustard
  • Wholegrain Mustard
  • Brown Mustard

The Mustard’s to eat sparingly on keto are:

  • Honey Mustard (French’s Honey Mustard has 1g of net carbs per teaspoon)
  • Garlic Aioli Mustard – despite it’s 0 carb count per teaspoon, it contains canola oil and sugar. These carbs may be too small to be required to disclose, but they will add up if you eat too much.
  • Horseradish Mustard – 1 gram of net carbs per serve

Mustards to Avoid on Keto are:

  • Specialty alcohol mustards such as bourbon mustard, whiskey mustard, beer flavored mustards etc. Reading the nutrition facts you could be forgiven for thinking these were okay on the keto diet. Take a closer look at the ingredients – many contain sugar, brown sugar, honey, molasses, corn starch and other additives not usually consumed on the keto diet.
  • Chipotle Mustard – the added sugar makes it 2 grams of carbs per teaspoon.
  • Fruit based mustards – often contains additional sugars, fruit juice or fruit concentrates which increase the carb count.
  • Maple Champagne Mustard – maple syrup, champagne, some brands also contain honey and white wine.
