Is Corn Gluten Free?

Yes, corn, in its natural form, is gluten-free. This might come as a surprise to many, especially since the protein in corn is sometimes referred to as “corn gluten.” But don’t be alarmed! “Corn gluten” is different from the gluten found in wheat, barley, and rye.

Katarina Mollo MEd, RDN, LDN, Director of Education at National Celiac Association confirms “corn is naturally gluten-free. The protein in corn is sometimes referred to as “corn gluten” but it is not harmful to those with celiac disease.”

However, it’s essential to be cautious. While corn itself is gluten-free, products made from corn might not always be. For instance, corn that comes in a sauce or with other ingredients could contain gluten. Always double-check the ingredients label to ensure the product is genuinely gluten-free.

The many faces of gluten-free corn

Numerous diets around the world rely on corn as a main food or ingredient. Here’s a breakdown of its various forms and their gluten status:

  1. Natural fresh corn: The kernels you relish straight off the cob? They’re gluten-free. But always be wary of corn that’s drenched in sauces or mixed with other ingredients, as they might be hiding gluten.
  2. Popcorn: While popcorn in its natural form is gluten-free, additives or flavourings might introduce gluten. Always read the label or make your own popcorn at home.
  3. Corn flour: Light and fine, corn flour is gluten-free in its essence. It’s a favourite in baking for its delicate texture. Always opt for corn flour labelled gluten-free (GF), like the ones we offer, to avoid any cross-contamination.
  4. Cornstarch: A fine powder derived by grinding the starchy portion of a corn grain. It’s a popular thickening agent for soups and gravies and, yes, it’s gluten-free. At Duinkerken, we ensure our cornstarch is free from cross-contamination, making it safe for your consumption.
  5. Cornmeal: Made from maize (dried corn), cornmeal is a coarse flour and is gluten-free. However, always be on the lookout for a gluten-free label to ensure safety.
  6. Hominy: Derived from dried corn kernels treated with an alkali, hominy is gluten-free. It’s a key ingredient in many products, including tortillas.

The benefits corn has for everyone

Corn is a powerhouse of nutrients and benefits, especially for those leading a health-conscious or gluten-free lifestyle

  • Energy-rich: Corn is a good source of carbohydrates, providing energy to keep you going throughout the day. For those looking to maintain a healthy weight, corn can be an excellent addition to their diet. Its high fiber content can promote feelings of fullness, reducing overall calorie intake.
  • High in fibre: Corn is a great source of dietary fibre, which aids in digestion, can help lower cholesterol levels, and supports overall gut health. A healthy digestive system is crucial for those with celiac disease, as their gut can be more sensitive and prone to inflammation.
  • Packed with vitamins: Corn is rich in B vitamins, especially niacin, thiamin, and riboflavin, which play crucial roles in metabolism and energy production.
  • Antioxidant abundance: Corn contains beneficial antioxidants like lutein and zeaxanthin, which can promote eye health and combat oxidative stress.
  • Supports bone health: Corn provides essential minerals like phosphorus and magnesium, which are vital for bone health and energy production.
  • Naturally gluten-free: Corn is inherently free from gluten, making it a safe and tasty option for those with gluten sensitivities or intolerances.
  • Easily integrable in diverse dishes: It can be grilled, boiled, roasted, used as baking flour, or even consumed raw. From salads and soups to main courses and baked desserts, corn can be seamlessly integrated into a variety of dishes, ensuring that those on a gluten-free diet have a plethora of tasty options.
