Gluten Free Facts and Myths
Share
Gluten-free menus, gluten-free aisles, gluten-free everything. But what is gluten, who actually needs to avoid it and does going gluten-free automatically make something healthier?
There’s plenty of confusion surrounding gluten and health. So let’s separate the gluten-free facts from the myths—and make it easier to understand what gluten-containing foods may mean for your diet and digestion.
What Is Gluten?
Gluten is a group of proteins naturally found in wheat, barley and rye. That means it shows up in obvious places like bread, pasta, cereal and baked goods—but it can also turn up in foods you might not expect, from sauces and salad dressings to soups and seasonings.
For most people, gluten can simply be part of a varied diet. Others need to avoid it because of celiac disease or wheat allergy. Some people may also experience symptoms associated with gluten-containing foods without having either condition, often referred to as non-celiac gluten sensitivity (NCGS).¹
And then there are people who simply choose to eat less gluten or notice that certain gluten-containing meals don’t always agree with their digestion.
The important part? These situations aren't all the same.
Why Do Some People Avoid Gluten?
There are several reasons someone might follow a gluten-free diet, and understanding the difference matters.
Celiac disease is a chronic digestive and immune disorder triggered by gluten. In people with celiac disease, eating gluten causes an immune reaction that damages the small intestine. A strict, lifelong gluten-free diet is the treatment.²
Wheat allergy is an allergic reaction to wheat. It is different from celiac disease and should be diagnosed and managed with appropriate medical guidance.
Non-celiac gluten sensitivity (NCGS) describes symptoms associated with eating gluten-containing foods in people who do not have celiac disease or a wheat allergy. Unlike celiac disease, there is currently no single diagnostic test that confirms NCGS.¹
Other people may choose a gluten-free diet based on personal preference or how they feel after certain foods.
Now that we've covered the basics, let's get into the gluten-free facts and myths.
FACT: Celiac Disease Requires Strict Gluten Avoidance
Celiac disease isn't the same thing as occasionally feeling uncomfortable after pizza night. It's a medical condition that requires strict avoidance of gluten.
For people with celiac disease, even small amounts of gluten can be a concern. Following a gluten-free diet helps relieve symptoms and allows the small intestine to heal.²
Important: Digestive enzyme supplements are not a substitute for a gluten-free diet for anyone with celiac disease.
FACT: Wheat Allergy Is Different From Celiac Disease
They may both involve avoiding certain foods, but wheat allergy and celiac disease are not interchangeable.
A wheat allergy is an allergic response to proteins found in wheat, while celiac disease is an autoimmune condition triggered by gluten. Wheat allergy can cause potentially serious allergic reactions and should be evaluated and managed by a healthcare professional.
FACT: Non-Celiac Gluten Sensitivity Is Different Again
Some people experience digestive or other symptoms associated with gluten-containing foods even though testing does not indicate celiac disease or wheat allergy. This is commonly referred to as non-celiac gluten sensitivity, or NCGS.¹
Research into NCGS continues, and symptoms alone can't tell you whether gluten is actually the culprit. That's one reason it's helpful to work with a healthcare professional rather than trying to diagnose yourself based on how you feel after a meal.
FACT: Gluten Can Hide in Unexpected Foods
Bread and pasta are easy. It's the less-obvious foods that can make gluten-free eating tricky.
Depending on their ingredients and preparation, hidden sources of gluten may include:
- Soy sauce
- Gravies and sauces
- Salad dressings
- Soups
- Seasoning blends
- Packaged and processed foods
If you need to strictly avoid gluten, reading food labels is essential. Wheat, barley and rye—and ingredients derived from these grains—can show up in foods where you wouldn't necessarily expect them.²
FACT: Oats Need a Little More Explanation
Oats themselves are naturally gluten-free. The catch? Conventional oats can come into contact with wheat, barley or rye while they're being grown, transported, processed or packaged.
For people who require strict gluten avoidance, appropriately labeled gluten-free oats can help reduce the risk of this cross-contact. People with celiac disease should follow the guidance of their healthcare provider or registered dietitian about including oats in their diet.²
FACT: Going Gluten-Free Can Take Some Planning
Eating gluten-free at home is one thing. Restaurants, vacations, parties and family gatherings can be another.
A little preparation can make things easier: check restaurant menus ahead of time, ask questions about ingredients and food preparation, read labels and bring a gluten-free option when you aren't sure what will be served.
There's also good news: plenty of everyday foods are naturally gluten-free, including fruits, vegetables, meat, fish, eggs, beans, nuts, seeds, rice and potatoes.²
Now for a few gluten-free myths that deserve clearing up.
MYTH: Gluten-Free Automatically Means Healthier
"Gluten-free" tells you something about gluten. It doesn't tell you everything about nutrition.
A gluten-free cookie is still a cookie. Packaged gluten-free breads, crackers, desserts and snacks can still contain refined carbohydrates, added sugars and other ingredients you'd find in their gluten-containing counterparts.
For people who medically need to avoid gluten, gluten-free foods are essential. But for the general population, there's no evidence that simply removing gluten makes a diet healthier.²
A balanced gluten-free diet can still focus on fruits, vegetables, proteins, legumes, nuts, seeds and naturally gluten-free whole grains.
MYTH: A Gluten-Free Diet Has to Be Extremely Restrictive
Going gluten-free certainly means saying goodbye to some familiar foods—or finding new versions of them—but it can also introduce a lot more variety to your plate.
Rice is just the beginning. Naturally gluten-free grains and alternatives include:
- Quinoa
- Buckwheat
- Millet
- Teff
- Amaranth
- Sorghum
Gluten-free eating doesn't have to mean a life without bread, crackers or baked goods either. It just means choosing versions made without gluten-containing ingredients and, when strict avoidance is necessary, paying attention to appropriate gluten-free labeling and cross-contact.
MYTH: Everyone Should Avoid Gluten
Nope. Gluten isn't inherently "bad," and not everyone needs to eliminate it.
People with celiac disease have a clear medical reason to avoid gluten, while people with wheat allergy need to avoid wheat according to their medical guidance. Some people with NCGS may also benefit from dietary changes under the guidance of a healthcare professional.¹
But many people tolerate gluten-containing foods normally. If that's you, there's no need to ditch your favorite sourdough just because "gluten-free" sounds healthier.
What If Gluten-Containing Meals Occasionally Bother My Digestion?
Here's where things can get confusing.
Maybe a big pasta dinner leaves you feeling overly full. Maybe pizza night occasionally brings some digestive drama. It's tempting to point the finger at gluten, but a meal contains a lot more than one protein.
Fat, dairy, carbohydrates, portion size and other ingredients can all affect how a meal feels during digestion. Occasional digestive discomfort after eating a gluten-containing food doesn't automatically mean you have celiac disease, a wheat allergy or gluten sensitivity.
It can, however, be a good reason to pay attention to patterns.
For people without celiac disease or a wheat allergy, digestive enzymes may provide support for the digestion of components of gluten-containing meals.* Learn more about GlutenEase®.

How Do I Know If Gluten Is a Problem for Me?
Your digestive experience is personal, but symptoms aren't a diagnosis.
Digestive and non-digestive symptoms can have many possible causes. If you regularly experience symptoms after eating or suspect you may have celiac disease, wheat allergy or another gluten-related condition, talk with a healthcare professional.
And there's one especially important reason to have that conversation before cutting out gluten: going gluten-free before being tested for celiac disease can affect the accuracy of diagnostic testing.³
In other words, don't let one uncomfortable meal convince you that gluten has to go forever.
Understanding the facts about gluten, paying attention to how different foods work for you and getting appropriate medical guidance when something doesn't feel right can help you make more informed choices—whether your plate includes gluten or not.
