Is mustard gluten-free? Inside America’s favorite yellow condiment

Hot dog and fries

“Hot dog, gluten-free bun, onions…wait, is mustard gluten-free? This barbecue is so much fun, I’d hate to have to leave early. But this dog would taste better with mustard. Mustard has to be gluten-free, right? It’s a condiment!”

When it comes to mustard and gluten, the answer isn’t always so clear. As most people with food intolerances know, condiments aren’t always in the safe zone. Let’s take a closer look at mustard, reasons why it may have gluten and some of our favorite brands so you can just focus on having fun at the next barbecue.

Is mustard gluten-free? It’s in the farming

In theory, mustard is gluten-free. But like a lot of theories, they don’t always prove to be true in reality. Mustard seeds do not have gluten, but it’s a lot more complicated than that even if the ingredient list is safe.

According to Agrifarming, mustard seeds are grown in dry, cool climates from September to October. India is number one in terms of production of mustard. In some cases, mustard seeds are grown as a single crop. In other cases, they can be grown alongside wheat and lentils, which is where the problems begin. Many farmers in Northern India mix wheat and mustard seed crops for more stability of crops and better yield. In a mixed crop situation, it’s difficult to prevent cross contamination.

The other factor that complicates matters is vinegar. Vinegar can be distilled from several sources, including rice, corn and wheat grain. Companies aren’t required to share their vinegar source so it can be difficult to tell if the vinegar in your mustard is made from gluten-free ingredients.

Without any definitive information about crops or vinegar sources, it could seem like it’s best to just ban mustard all together. But there are reasons why mustard can be good for you beyond just adding flavor to your food.  

Health Benefits of Mustard

According to Agrifarming, mustard has many health benefits. Did you know that mustard helps stimulate hair growth? Helps prevent gastrointestinal cancer? Helps relieve arthritic and muscle pain? Helps lower cholesterol? Helps in weight loss and anti-aging? It’s kind of like a miracle condiment. And you just thought it added flavor!

Let’s figure out which mustards are gluten-free for you to eat so you can start experiencing some of these benefits.
