How to Avoid Gluten: 7 Essential Steps for a Gluten-Free Diet

QUICK SUMMARY

To avoid gluten, eliminate wheat, barley, rye, triticale, and foods made from them, then protect your food from cross-contact. For people with celiac disease, a strict gluten-free diet is a lifelong medical necessity. Wheat allergy and non-celiac gluten or wheat sensitivity are different conditions and require individualized guidance. (1, 2)

The 7 essential steps are:

1. Know the gluten-containing grains: Avoid wheat, barley, rye, triticale, and their derivatives.
2. Choose oats carefully: Oats are naturally gluten-free, but cross-contact is common, so people with celiac disease should choose oats labeled gluten-free.
3. Read labels correctly: On FDA-regulated foods, a “gluten-free” claim means the finished food must contain less than 20 parts per million of gluten. Third-party certification is helpful but not required. (3)
4. Prevent kitchen cross-contact: Keep crumbs, shared toasters, colanders, cutting surfaces, utensils, and double-dipped condiments from contaminating gluten-free food.
5. Choose naturally gluten-free foods first: Build meals around vegetables, fruits, beans, nuts, seeds, potatoes, rice, quinoa, clean proteins, and other whole foods.
6. Ask direct questions when dining out: Tell restaurant staff that gluten avoidance is medically necessary when that is true, and ask about shared fryers, grills, preparation surfaces, sauces, and breading.
7. Do not blame gluten for everything: Bread is a Biblical food, and gluten is not inherently a toxin for everyone. Celiac disease is the important exception because gluten itself is the established trigger. For people without celiac disease, symptoms after American wheat may involve fructans or other wheat components, processing and fermentation differences, individual expectations, or other factors still being studied. (4, 5, 19)

Avoiding gluten sounds simple until you start reading labels, sharing a kitchen, eating at restaurants, and realizing how many places wheat, barley, and rye can hide.

For our family, reducing gluten has long been part of the way we choose to eat. But there is an important distinction we need to make right from the beginning: someone with celiac disease is not simply following a wellness trend. Gluten triggers an immune reaction that damages the small intestine, and strict lifelong avoidance is the treatment. Someone with wheat allergy has a different immune condition, and someone with non-celiac wheat or gluten sensitivity may have symptoms without the intestinal damage seen in celiac disease. (1, 2)

That difference changes how careful you need to be, how you approach testing, and what “gluten-free” actually means.

And one more thing before you clean out the pantry: if you think you may have celiac disease but have not been tested, talk with your healthcare provider before starting a gluten-free diet. Removing gluten before blood testing and biopsy can make celiac disease harder to diagnose accurately. (1)

Who Needs to Avoid Gluten?

The phrase “gluten sensitivity” gets used very loosely, but several different conditions can sit behind a bad reaction to wheat or gluten. Understanding the difference is one of the most important steps you can take.

Celiac Disease

Celiac disease is a chronic immune-mediated disorder triggered by gluten in genetically predisposed people. Gluten from wheat, barley, and rye activates an immune response that damages the lining of the small intestine. About 1% of people worldwide are estimated to have celiac disease. (2, 6)

Celiac disease can cause digestive symptoms, but it is not merely a digestive problem. Untreated disease can be associated with iron-deficiency anemia, nutrient deficiencies, low bone density, fatigue, dermatitis herpetiformis, infertility, neurological symptoms such as peripheral neuropathy or headaches, mental health problems, and other autoimmune conditions. Some people have few obvious digestive symptoms at all. (6, 7)

This is where an older version of this article went too far. It listed anxiety, autism, cancer, dementia, epilepsy, lupus, rheumatoid arthritis, schizophrenia, and many other conditions as though eating gluten broadly causes them in everyone. That is not what the research shows.

A more accurate way to say it is this: celiac disease is a systemic autoimmune disorder, and a wide range of gastrointestinal, nutritional, neurological, psychiatric, reproductive, and autoimmune conditions have been reported in association with it. Association does not mean that gluten causes every one of those diseases in the general population. (7, 8)

For someone with diagnosed celiac disease, however, strict gluten avoidance is not optional. It is the cornerstone of treatment.

Wheat Allergy

Wheat allergy is different from celiac disease. It is an allergic immune response to proteins in wheat and can cause symptoms such as hives, swelling, digestive symptoms, wheezing, or in severe cases anaphylaxis.

A person with wheat allergy may need to avoid wheat very strictly, but “wheat-free” and “gluten-free” are not interchangeable terms. Barley and rye contain gluten but are not wheat.

If you have a true food allergy, follow the emergency and avoidance plan provided by your allergy specialist.

Non-Celiac Gluten or Wheat Sensitivity

Some people experience digestive or extraintestinal symptoms when they eat wheat but test negative for celiac disease and wheat allergy. This is commonly called non-celiac gluten sensitivity or, increasingly, non-celiac wheat sensitivity.

This area is much more complicated than it once appeared.

A 2025 Lancet review concluded that there is still no definitive biomarker for non-celiac gluten sensitivity, and symptom generation may involve fermentable carbohydrates, nocebo effects, gluten, or other wheat components depending on the individual. A 2025 scoping review similarly found that gluten is the most studied potential trigger but that controlled evidence remains inconsistent. (4, 5)

So when someone says, “I feel better without wheat,” we believe that experience matters. What we should not do is automatically assume the mechanism is celiac disease, gluten itself, glyphosate, FODMAPs, or any one ingredient without proper evaluation.

Gluten Is Not Inherently the Problem for Everyone

Medical consensus does not require the general population to follow a gluten-free diet. NIDDK notes that researchers have not found evidence that a gluten-free diet by itself improves health or promotes weight loss for everyone who does not have celiac disease or another gluten-related condition. (1)

This matters to us because bread is a Biblical food. Jesus ate bread with His disciples. Scripture describes the Promised Land as “a land of wheat and barley” (Deuteronomy 8:8), and at the Last Supper, “Jesus took bread, and after blessing it broke it” (Matthew 26:26). Jesus even used bread to describe Himself: “I am the bread of life” (John 6:35).

So our ministry position is not that wheat, bread, or gluten is inherently evil. God created grain as food. For people with celiac disease, gluten itself is the established trigger and must be avoided. For everyone else, we should be careful not to turn a Biblical food into the villain when the real concern may be the way modern wheat is grown, processed, formulated, fermented, and consumed.

Our Natural Living Family position is more cautious about conventional American wheat and ultra-processed grain products. We prefer to minimize them and emphasize organic whole foods in our home. That is a ministry and lifestyle recommendation, not a claim that every person medically requires a gluten-free diet.

If you choose to avoid gluten because you simply feel better without it, you can still do so wisely. Just make sure your diet remains rich in fiber, minerals, protein, and whole foods rather than replacing wheat with a shelf full of ultra-processed gluten-free cookies and crackers.

The Italian Paradox: Why People Tolerate Grains Overseas

We hear this story over and over: someone says wheat or pasta or bread bothers them at home in America, then they travel to Italy or another European country, eat bread and pasta freely, and feel surprisingly good.

People sometimes call this the “Italian paradox.” It is not a recognized medical diagnosis or a proven scientific phenomenon, but the experience is common enough that it deserves a serious look instead of being dismissed.

And I think it teaches an important lesson: gluten is not the problem for every person who feels worse after eating American wheat products.

Italy Does Not Have Gluten-Free Wheat

First, let's clear up the biggest misconception. Italian wheat still contains gluten. Italy also has plenty of celiac disease. In fact, Italy's Ministry of Health estimates celiac disease affects about 1% of the population, and a multicenter screening study of Italian schoolchildren found a prevalence of 1.65%. (24, 25)

So if you have diagnosed celiac disease, do not test the Italian paradox on vacation. A beautiful loaf of bread in Tuscany still contains gluten and can still trigger celiac disease.

The paradox applies to a different group: people who do not have celiac disease or severe wheat allergy but has experienced that American wheat or bread makes them feel bloated, foggy, tired, achy, or generally unwell.

Europe Has Different Rules Around Preharvest Glyphosate

There is a real regulatory difference between the United States and the European Union that matters to this conversation.

As discussed below, current U.S. pesticide labels permit certain preharvest glyphosate applications to mature wheat. By contrast, the European Commission's current glyphosate conditions specifically state that uses for desiccation to control harvest timing or optimize threshing are not permitted in the EU. Italy operates under those EU rules. (9, 18)

That does not mean Italy has banned glyphosate entirely. It has not. But Europe does not allow the particular glyphosate desiccation use that concerns many of us when we talk about spraying grain near harvest.

For families trying to understand why bread can seem different overseas, that distinction is worth knowing.

Traditional Fermentation May Change What Your Gut Encounters

Gluten is also not the only component of wheat capable of causing digestive symptoms.

In a randomized double-blind crossover trial of people who believed they had non-celiac gluten sensitivity, researchers found that fructans caused more gastrointestinal symptoms than gluten. Another controlled trial found that only a minority of self-identified gluten-sensitive participants could reliably distinguish gluten from placebo. (19, 20)

Fructans are fermentable carbohydrates naturally present in wheat. Long sourdough fermentation can substantially reduce fructan content, although not every Italian loaf is traditionally fermented and not every study shows better symptom tolerance from sourdough. (21, 22)

That gives us a plausible reason some people may tolerate certain traditionally made breads better without pretending we have proven the explanation for every traveler who comes home saying, “I ate bread every day in Italy and felt amazing.”

The Ingredient List Can Be Different Too

American and European food regulations are not identical. One simple example is azodicarbonamide, a flour-treatment and dough-conditioning agent permitted by FDA in the United States under specified conditions but not authorized as a food additive in the European Union. (23, 26)

That does not mean all American bread contains it or that this one additive explains wheat sensitivity. It simply reinforces the broader point: a modern packaged bread product is not synonymous with wheat itself. Grain variety, pesticide practices, milling, fermentation time, additives, serving size, and the rest of the meal can all differ from one food system to another.

Why We Avoid Conventional Wheat: Gluten, Glyphosate & Farming

One of the original themes of this article was our concern about conventional wheat farming, especially the preharvest use of glyphosate. The Italian paradox gives that concern useful context, because European and U.S. preharvest rules are not identical. That concern deserves to stay, but the science needs to be described accurately.

Preharvest Glyphosate on Wheat Is a Real Practice

Glyphosate can legally be used before harvest on some U.S. wheat crops when the grain has already reached the hard-dough stage. A current 2026 EPA-approved glyphosate label permits preharvest application to wheat after the hard-dough stage at 30% grain moisture or less, with at least seven days before harvest. Penn State Extension gives essentially the same agronomic guidance. (9, 10)

So, yes, preharvest glyphosate application on wheat is real.

But it is not accurate to say that conventional wheat fields are universally “drenched with Roundup several days before harvest” specifically to force the crop to seed or artificially boost yield. Current labels describe the practice primarily as preharvest weed control, and application is restricted to physiologically mature grain.

That distinction matters because we do not need to exaggerate a concern to make a case for choosing organic food when possible.

Does Glyphosate Cause Celiac Disease or Gluten Sensitivity?

Earlier versions of this article stated that researchers had “proven” glyphosate, rather than gluten, annihilates gut flora and causes the chronic inflammation behind gluten-related disease. The current evidence does not support wording that strong.

A frequently cited 2013 paper proposed glyphosate as a major causal factor in celiac disease, but it was a hypothesis-based review, not a controlled human trial demonstrating causation. (11)

Research on glyphosate and the intestinal microbiome has continued. A 2024 systematic review reported changes in microbiota, intestinal permeability, mucus secretion, and gut structure in experimental studies, but the review was based largely on animal models. Those findings are relevant to toxicology research, but they do not prove that dietary glyphosate residues cause celiac disease or non-celiac wheat sensitivity in people. (12)

Even the broader non-celiac wheat-sensitivity literature remains unsettled. The 2025 scoping review found insufficient controlled evidence to identify a single wheat component as the cause of symptoms across patients. (5)

7 Essential Tips to Avoid Gluten in Your Diet

Living gluten-free may feel overwhelming initially, but it becomes much easier once you establish a routine. The goal is not fear. The goal is clarity.

1. Identify the Gluten-Containing Grains

First and foremost, know what actually contains gluten.

Avoid:

• Wheat
• Barley
• Rye
• Triticale
• Bulgur
• Durum
• Einkorn
• Emmer and farro
• KAMUT khorasan wheat
• Semolina
• Spelt
• Wheat bran
• Wheat germ
• Graham flour
• White flour
• Whole wheat flour

All of these wheat varieties contain gluten.

2. Choose Oats Carefully

Oats deserve their own category because they are often misunderstood.

Pure oats do not naturally contain wheat, barley, or rye gluten. The problem is cross-contact during growing, transport, milling, and processing. NIDDK and the Celiac Disease Foundation recommend that people with celiac disease choose oats specifically labeled gluten-free. (1, 13)

A small subset of people with celiac disease may also react to avenin, an oat protein, even when the oats meet gluten-free standards. If you have celiac disease, discuss oats with your gastroenterologist or dietitian if they seem to trigger symptoms.

3. Eliminate or Replace High-Risk Processed Foods

Many familiar foods are traditionally made with wheat, barley, or rye:

• Beer and malt beverages
• Bread
• Cakes
• Many cereals
• Cookies
• Couscous
• Crackers
• Flour tortillas
• Muffins
• Pasta
• Pastries
• Traditional soy sauce
• Some gravies, soups, sauces, marinades, and seasoning mixes

The good news is that we have far more options today than we did years ago. Rice, potatoes, quinoa, buckwheat, amaranth, millet, sorghum, teff, beans, cassava, nuts, seeds, fruits, and vegetables are naturally gluten-free when they have not picked up gluten through processing or preparation.

This is one of the reasons we prefer a whole-food approach. The fewer ingredients a food has, the easier it is to know what you are eating.

4. Master Gluten-Free Label Reading

This is where a lot of outdated gluten-free advice causes unnecessary confusion.

You do not need an “official certification mark” for an FDA-regulated food to legally be labeled gluten-free. Third-party certification is optional. If an FDA-regulated packaged food says “gluten-free,” “no gluten,” “free of gluten,” or “without gluten,” it must meet FDA's gluten-free standard, including less than 20 parts per million of gluten. (3, 14)

Still, read the ingredient list.

Watch for:

• Wheat and wheat varieties such as spelt, durum, semolina, farro, einkorn, and KAMUT
• Barley
• Rye
• Malt, malt extract, malt syrup, malt flavoring, and malt vinegar, which are generally barley-derived
• Brewer's yeast when the gluten source or processing is uncertain
• Wheat starch unless the finished food is properly labeled gluten-free or the starch is specifically processed to meet gluten-free requirements

Two corrections are important here.

Modified food starch is not automatically a hidden gluten source in the United States. If wheat is used in an FDA-regulated food, wheat must be declared. Modified food starch from corn, potato, or tapioca is gluten-free. (15)

Likewise, “natural flavors” and “spices” are not automatically gluten-containing. If an FDA-regulated flavor contains wheat protein, wheat must be declared under allergen-labeling law. The bigger U.S. labeling gap is barley and rye, which are not currently treated as major food allergens the way wheat is. That is why checking for words such as malt and barley remains important. (13)

5. Prevent Gluten Cross-Contact at Home

For celiac disease, the challenge is not only removing obvious gluten. Gluten-free food can pick up gluten when it comes into contact with crumbs, flour, utensils, appliances, or preparation surfaces used for gluten-containing foods. NIDDK specifically recommends storing and preparing gluten-free foods separately in shared households. (1)

Practical ways to reduce cross-contact include:

• Use a dedicated toaster for gluten-free bread or use a protective toaster bag.
• Keep gluten-free foods away from loose wheat flour and bread crumbs.
• Use a thoroughly cleaned or dedicated colander for gluten-free pasta.
• Replace deeply scratched or porous preparation tools if they cannot be cleaned effectively.
• Use squeeze bottles or separate jars of peanut butter, mayonnaise, jelly, butter, and other foods that are easily contaminated by double-dipping.
• Clean counters, cutting boards, cookware, and utensils before preparing gluten-free food.
• Store gluten-free foods where crumbs from gluten-containing foods will not fall into them.

If the whole household is transitioning to gluten-free, give cabinets and drawers a good cleaning and remove old crumbs from shelves, utensil trays, toaster areas, and food-storage spaces.

Bulk bins are another concern. The Celiac Disease Foundation recommends avoiding bulk-bin grains because shared scoops and neighboring products create opportunities for cross-contact. (16)

6. Dine Out Without Guessing

Dining out can be one of the hardest parts of a strict gluten-free diet, particularly with celiac disease.

Before you go:

• Check the restaurant menu online for gluten-free choices.
• Call ahead during a slower time if you need to ask detailed questions.
• Look for restaurants experienced in serving people with celiac disease.

At the restaurant, ask:

• Is the fryer shared with breaded foods?
• Is the grill or cooking surface shared with buns, pancakes, or flour tortillas?
• Are separate utensils and preparation surfaces used?
• Does the sauce, marinade, seasoning, or gravy contain flour, malt, soy sauce, or another gluten ingredient?
• Can the meal be prepared simply with clean equipment?

One important correction from the older article: do not tell restaurant staff you have a food allergy if you do not. Celiac disease is autoimmune, not an IgE-mediated wheat allergy, and non-celiac wheat sensitivity is different again.

Use language that is both truthful and clear:

• “I have celiac disease and need a medically strict gluten-free meal with cross-contact precautions.”
• “I have a wheat allergy.”
• “I need to avoid gluten for a medical condition. Can you tell me how this is prepared?”

That gives the kitchen accurate information without mislabeling your condition.

7. Be Extra Careful With Buffets, Shared Fryers & Social Events

Buffets, salad bars, potlucks, church meals, and shared snack tables are common places for gluten-free foods to pick up crumbs.

Use caution with:

• Shared serving utensils
• Croutons near salad ingredients
• Butter and dips used with regular bread
• Shared fryers
• Pizza ovens or surfaces with loose flour
• Communion bread or wafers
• Homemade dishes when the cook is unsure about ingredients or cross-contact

For strict celiac management, sometimes the simplest choice is to bring your own food. There is no shame in protecting your health.

Gluten-Free Diet FAQs

What foods contain gluten?

Gluten naturally occurs in wheat, barley, rye, triticale, and products made from those grains. That includes wheat varieties such as durum, semolina, spelt, farro, einkorn, emmer, and KAMUT khorasan wheat. Barley-derived malt is another common source. (1, 13)

Does organic wheat contain gluten?

Yes. Organic farming can reduce exposure to certain conventional pesticides, but organic wheat still naturally contains gluten. A person with celiac disease cannot make wheat safe simply by choosing organic.

Is gluten-free wheat starch really gluten-free?

It can be. FDA regulations allow specially processed wheat starch in a food labeled gluten-free when the finished product meets the gluten-free standard of less than 20 ppm. If wheat appears on the same label, additional wording is required to explain that it has been processed to meet FDA gluten-free requirements. (3)

Are oats gluten-free?

Oats are naturally gluten-free, but cross-contact with wheat, barley, or rye is common. People with celiac disease should choose oats labeled gluten-free. A minority may still react to the oat protein avenin. (1, 13)

Does “wheat-free” mean “gluten-free”?

No. A wheat-free food can still contain barley, rye, malt, or another source of gluten.

Does “gluten-free” have to be certified?

No. Third-party gluten-free certification is optional. On FDA-regulated packaged foods, the words “gluten-free,” “no gluten,” “free of gluten,” and “without gluten” are regulated claims and the food must meet FDA's less-than-20-ppm standard. Certification can add another layer of oversight, but it is not what makes the FDA claim legally valid. (3, 14)

Can natural flavors contain gluten?

They can contain grain-derived ingredients, but “natural flavors” should not automatically be treated as gluten. In FDA-regulated foods, wheat protein used in a flavor must be declared as wheat. Barley and rye are not currently major allergens under U.S. law, so people with celiac disease still need to watch for barley-derived ingredients such as malt and contact the manufacturer when a label is genuinely unclear. (13)

Is modified food starch gluten-free?

Usually, yes, in U.S. foods. Modified food starch is commonly made from corn, potato, or tapioca. If it comes from wheat in an FDA-regulated food, wheat must be declared. A food can also contain specially processed wheat starch and still be labeled gluten-free if the finished product meets FDA requirements. (3, 15)

If gluten is Biblical, why do some people feel better without American wheat?

That is one reason the “Italian paradox” is so interesting. For people without celiac disease or wheat allergy, symptoms attributed to gluten may sometimes involve other wheat components such as fructans, differences in fermentation and processing, individual expectations, or other factors. European rules also prohibit glyphosate use for preharvest desiccation to control harvest timing or optimize threshing, while U.S. labels permit certain preharvest applications to mature wheat. (18, 19, 20)

None of that proves a single explanation for why someone feels better eating bread in Italy. It does support our point that gluten itself should not automatically be blamed for every reaction to modern wheat products.

Does glyphosate cause celiac disease?

Current human evidence has not established glyphosate as a cause of celiac disease. Celiac disease is an immune-mediated disorder triggered by gluten in genetically predisposed people. Experimental research raises legitimate questions about glyphosate and the gut microbiome, but much of that evidence comes from animal models and cannot be translated into proof of human celiac causation. (2, 12)

Our family still prefers organic food when practical as part of reducing pesticide exposure. That is separate from the medical need to remove gluten in celiac disease.

Should I go gluten-free before getting tested for celiac disease?

No, not if you can safely continue eating gluten while you are being evaluated. NIDDK advises talking with your doctor about testing before beginning a gluten-free diet because removing gluten can make diagnostic tests less accurate. (1)

What is the healthiest way to eat gluten-free?

Build your diet around naturally gluten-free whole foods instead of relying primarily on gluten-free replacement products. Vegetables, fruits, beans, nuts, seeds, potatoes, rice, quinoa, buckwheat, clean proteins, and healthy fats give you a much stronger nutritional foundation than simply swapping conventional cookies for gluten-free cookies.

If you remove wheat and other fortified grains, pay attention to fiber, iron, folate, B vitamins, and overall dietary variety.

How careful do I need to be about cross-contact?

If you have celiac disease, cross-contact matters because even small amounts of gluten can interfere with a medically strict gluten-free diet. FDA's regulatory threshold for foods labeled gluten-free is less than 20 ppm, and NIDDK recommends separate storage and preparation practices to prevent gluten transfer. (1, 3)

For non-celiac wheat sensitivity, individual tolerance may differ. Work with a knowledgeable clinician or dietitian if you are unsure how strict you need to be.

Living the Gluten-Free Lifestyle

Living gluten-free requires vigilance, but it does not require fear.

Once you know the grains, understand labels, protect your food from cross-contact, and learn what questions to ask, the routine becomes second nature.

For celiac disease, strict gluten avoidance is essential. For wheat allergy, the strategy must match the allergy. For non-celiac wheat sensitivity, the science is still evolving and individual triggers can differ. And for families like ours who prefer to minimize conventional American wheat and processed grain products, we can make that choice without declaring that gluten itself is bad for everyone. Bread is Biblical food. Our concern is what modern agriculture and industrial processing can add to, remove from, or change about that food.

That is what informed natural living looks like to us: understand the research, tell the truth about what it does and does not prove, choose cleaner foods whenever possible, and make practical decisions that help your family thrive.
