Are Corn Nuts brand gluten-free?

Gluten-free diets have become increasingly popular in recent years, with more and more people choosing to avoid gluten for medical or lifestyle reasons. For those following a gluten-free diet, it can be challenging to find tasty, gluten-free snack options. One popular snack food is Corn Nuts, a crunchy corn snack made by the Frito-Lay company. But are Corn Nuts gluten-free?

What is Gluten?

Gluten is a protein found in grains like wheat, barley and rye. For most people, gluten doesn’t cause any issues. However, for those with celiac disease or non-celiac gluten sensitivity, gluten can trigger an autoimmune reaction that damages the small intestine. Even small amounts of gluten can cause issues for those who are gluten intolerant. Common symptoms of gluten intolerance include abdominal pain, bloating, diarrhea, constipation, vomiting, fatigue, headache and skin rashes. The only treatment for celiac disease or gluten sensitivity is following a strict lifelong gluten-free diet by avoiding all foods and products containing gluten.

Why Follow a Gluten-Free Diet?

There are a few key reasons someone may need to follow a gluten-free diet:

Celiac Disease

Celiac disease is an autoimmune disorder that causes damage to the small intestine when gluten is ingested. It affects around 1% of the population. The only treatment is a strict gluten-free diet.

Non-Celiac Gluten Sensitivity

Some people test negative for celiac disease but still experience symptoms when they eat gluten. This is known as non-celiac gluten sensitivity. It’s estimated to impact anywhere from 0.5% to 13% of the population. A gluten-free diet helps manage symptoms.

Gluten Allergy

It’s possible to have an allergy to gluten. Symptoms may include digestive issues, hives, asthma and anaphylaxis after eating gluten. Avoiding all gluten is necessary to prevent an allergic reaction.

Other Health Reasons

Some follow a gluten-free diet to help manage conditions like autism, ADHD, rheumatoid arthritis, infertility or neurological issues. Gluten elimination diets may help reduce inflammation and improve overall health.

Weight Loss

Going gluten-free naturally leads some to eat more fruits, vegetables and lean proteins. The diet may help with losing weight or maintaining a healthy weight for some people.

Lifestyle Choice

Eating gluten-free has grown in popularity and some choose to avoid gluten-containing grains as a lifestyle choice, even without an underlying medical reason.

What Foods Contain Gluten?

Gluten is found in several common grains:

– Wheat
– Barley
– Rye
– Triticale

Any foods or products made with these gluten-containing grains should be avoided on a gluten-free diet. This includes:

– Bread
– Pasta
– Cereal
– Baked goods
– Beer
– Malt vinegar
– Soy sauce
– Seasonings
– Soup bases
– Bouillon cubes
– Sauces
– Gravies

It’s important to read ingredient labels carefully, as gluten can lurk in unexpected places like salad dressing, seasonings, sauces and soups.

Are Corn Nuts Gluten-Free?

The good news is that yes, original Corn Nuts are certified gluten-free to less than 20 ppm (parts per million) of gluten by the Gluten-Free Certification Organization (GFCO).

According to Frito-Lay, Corn Nuts are made from just three simple ingredients: whole corn kernels, vegetable oil and salt. Corn by nature is gluten-free, and no gluten-containing ingredients are used in the production process. Frito-Lay also states their manufacturing facilities have procedures in place to prevent cross-contamination with allergens like gluten.

So plain, original flavor Corn Nuts can safely be included in a gluten-free diet. Those with celiac disease or gluten sensitivity don’t need to worry about Corn Nuts containing any traces of gluten.

Are All Corn Nuts Flavors Gluten-Free?

While the original Corn Nuts are certified gluten-free, it’s important to check the ingredients list on other flavor varieties. Frito-Lay states that Ranch, BBQ and Chili Picante flavors contain a wheat-based ingredient and are therefore NOT gluten-free.

Other seasoned flavors like Nacho Cheese, Jalapeno Cheddar and Hot Wings are also made in facilities that process wheat-based ingredients, so cross-contamination is possible. Individuals with celiac disease or severe gluten intolerance may want to avoid the flavored varieties.

Here’s a summary of which Corn Nuts flavors are gluten-free according to current ingredients:

Gluten-Free Corn Nuts Flavors Not Gluten-Free Corn Nuts Flavors
  • Original
  • Lightly Salted
  • Ranch
  • BBQ
  • Chili Picante
  • Nacho Cheese
  • Jalapeno Cheddar
  • Hot Wings

It’s always smart to double check the ingredient list for any new flavors released. Ingredients can change over time. When in doubt, contact Frito-Lay directly to inquire about the gluten-free status of a particular flavor.

Are Corn Nuts Processed in a Facility with Wheat?

Frito-Lay states that Corn Nuts may be processed on shared equipment that also processes wheat-containing ingredients. While they have procedures in place to minimize cross-contamination, the risk isn’t fully eliminated.

For people with celiac disease or who are highly sensitive, shared facilities and equipment are a concern. Even tiny amounts of cross-contamination can trigger symptoms and intestinal damage in those who are gluten intolerant.

Those managing celiac disease or gluten sensitivity may wish to avoid Corn Nuts and other Frito-Lay snacks processed on shared lines altogether, even if the product is labeled gluten-free.

Corn Nuts Labeling and Certification

The original Corn Nuts flavor contains no gluten ingredients and is certified gluten-free by the GFCO. This independent certification means the product has been rigorously tested to verify gluten levels test below 20 ppm.

Frito-Lay clearly labels which flavors contain gluten, like Ranch, BBQ and Chili Picante. They also indicate that other seasoned varieties may have been processed in facilities that handle wheat.

However, there is no “Processed in a facility with wheat” statement on the packaging. Those sensitive to cross-contamination need to look up this information on the company’s website. More prominent labeling would better inform gluten-free consumers.

Are Corn Nuts Safe for Celiacs and Gluten Sensitivity?

Plain, original flavor Corn Nuts that are certified gluten-free are a safe bet for anyone following a gluten-free diet. The corn and oil used to produce them are naturally free of gluten. With certification testing, you can feel confident that Corn Nuts contain under 20 ppm of any traces of gluten.

However, those with celiac disease or who are highly sensitive need to use caution with the other flavored varieties, even if they don’t contain gluten ingredients. Due to the risk of cross-contamination from shared equipment and facilities, seasoned Corn Nuts may not be safe for those who react to very small amounts of gluten.

Naturally gluten-free whole foods like fruits, vegetables, eggs, meat, seafood, nuts and seeds are less likely to have cross-contamination issues. Those with celiac disease and gluten sensitivity may wish to focus on these whole, single-ingredient foods for the bulk of their snacks and diet.

Tips for Safely Enjoying Corn Nuts on a Gluten-Free Diet

Here are some tips for safely enjoying Corn Nuts on a gluten-free diet:

– Stick to original flavor Corn Nuts that are certified gluten-free. Avoid seasoned varieties.

– Check the ingredients list and gluten-free designations whenever buying Corn Nuts, even if purchased previously. Formulations can change over time.
