“Why does my stomach still hurt despite giving up bread?”
That question sent me down a rabbit hole of investigating hidden gluten sources.
Through my journey into basic nutrition, I discovered that giving up obvious foods high in gluten was just the beginning.
Even as someone passionate about healthy eating, I was shocked to learn how this sneaky protein lurks in everything from soy sauce to vitamin supplements.
After years of accidentally glutening myself with seemingly safe foods, I’ve learned the secrets of spotting hidden sources.
Ready to discover what might be secretly triggering your symptoms?
Let’s uncover the unexpected places gluten loves to hide and learn how to make gluten-free choices that support your health.
Key Takeaways
What Is Gluten and Why It Can Be Bad for You?
Ever wonder why bread dough gets stretchy when you knead it?
That’s gluten in action—a family of proteins found in wheat, barley, and rye that creates the elastic network, giving bread its chewy texture.(1)
But gluten’s role extends beyond just making bread rise, and understanding this protein has become crucial for anyone experiencing sensitivity to it.
PRO TIP: When baking gluten-free, combine flours like rice, almond, and tapioca to mimic gluten’s binding properties. I’ve found that adding xanthan gum helps achieve that stretchy texture we associate with regular bread.
Think of gluten as the food industry’s favorite binding agent. Manufacturers add it to countless products because it:
- Improves texture and mouthfeel
- Creates structure in processed foods
- Acts as a natural preservative
- Provides cheap protein content
- Helps maintain product shape
Beyond obvious sources like bread and pasta, gluten hides in surprising places.
What’s particularly tricky is that gluten appears under various names on labels – from “modified food starch” to “natural flavors.“
Cross-contamination presents another significant challenge.
Naturally, gluten-free foods can become unsafe when processed on shared equipment or prepared in kitchens that handle wheat products.(2)
This is particularly crucial for celiac disease patients, where even tiny amounts can trigger an immune response.
The health impacts of gluten sensitivity can be wide-ranging and sometimes surprising.
While digestive issues are common, many people experience:
- Chronic inflammation and joint pain
- Brain fog and fatigue
- Skin problems and rashes
- Nutrient absorption issues
- Mood changes and anxiety
Dedicate specific cooking tools (cutting boards, colanders, toaster) for gluten-free foods only.
Also, consider having a separate toaster for gluten-free bread, using separate condiment jars, and cleaning surfaces thoroughly before preparing gluten-free meals.
For those sensitive to gluten, the impact goes beyond just digestive discomfort.
Gluten can trigger an immune response that affects multiple body systems.
Some people experience immediate reactions, while others might not notice symptoms for days, making identifying gluten as the culprit is challenging.
Understanding gluten’s pervasive nature in our food supply helps explain why simply avoiding bread isn’t enough for those who need to be gluten-free.
Whether you have celiac disease or non-celiac gluten sensitivity or choose to avoid gluten for other health reasons, awareness of both obvious and hidden sources becomes essential for maintaining your health.
What makes modern gluten avoidance particularly challenging is the protein’s prevalent use in food manufacturing.
As processed foods become more common, so does our exposure to gluten in unexpected places.
This makes reading labels and understanding food production processes crucial for anyone maintaining a gluten-free lifestyle.
11 Foods High in Gluten
Think you’re avoiding gluten by skipping bread and pasta?
The surprising truth is that gluten lurks in many unsuspected places, particularly in everyday condiments and sauces.
After discovering my own gluten intolerance, I’ve learned to become a detective when it comes to identifying hidden sources of this protein.
1. Soy Sauce and Asian Condiments
Most people are shocked to learn that traditional soy sauce contains nearly as much gluten as bread.
The reason? Wheat is one of the main ingredients in conventional soy sauce, and it is used alongside soybeans in fermentation.
This centuries-old practice was designed to create a deeper flavor profile and thicker texture.
Still, it makes these condiments problematic for those avoiding gluten.
Popular brands containing gluten include:
- Kikkoman Regular Soy Sauce
- La Choy Soy Sauce
- Many teriyaki sauces
- Hoisin sauce
- Oyster sauce
- Sweet and sour sauces
LABEL TIP: Watch out for ingredients like “wheat,” “hydrolyzed wheat protein,” or “modified food starch” in Asian condiments. Even products labeled “naturally brewed” typically contain wheat.
Fortunately, gluten-free alternatives have become widely available.
When shopping for Asian condiments, look specifically for “gluten-free” certification, as even naturally gluten-free ingredients can be cross-contaminated during production.
For cooking Asian dishes at home, try these gluten-free alternatives:
- Certified gluten-free tamari
- Coconut aminos
- Gluten-free hoisin sauce (check labels carefully)
- Fish sauce (most brands are gluten-free, but verify)
- House-made marinades using gluten-free ingredients
Remember, even if a sauce or condiment doesn’t taste ready, it may still contain significant amounts of gluten.
Always check labels, and when in doubt, contact the manufacturer directly.
2. Processed Meats
“But how can my hot dog contain gluten?”
This was precisely my reaction when I first learned about hidden gluten in processed meats.
I remember the shock and frustration I felt when I discovered that these protein-packed foods might seem naturally gluten-free, but the reality is different.
Let me share what I’ve learned about navigating this unexpected gluten source.
The meat industry has a bit of a secret: many processed meats use gluten as a cheap and effective binding agent.
Your seemingly innocent deli turkey or breakfast sausage might contain as much gluten as a slice of bread.
The most surprising part? It’s legal for manufacturers to add wheat-based fillers without prominently displaying them on the front label.
This is why reading labels carefully is crucial to avoid hidden gluten.
After accidentally glutening myself with “all-natural” sausages multiple times, I learned that “natural” doesn’t mean gluten-free.
This experience taught me to be more vigilant and not to assume that all-natural products are safe.
Now, I stick to certified gluten-free brands or whole cuts of meat.
Common processed meats containing gluten:
- Hot dogs (even premium brands)
- Deli meats (exceptionally seasoned varieties)
- Sausages (both fresh and cured)
- Pre-made meatballs
- Frozen meat products
- Canned meat products
The good news? You don’t have to give up your favorite meat products.
Safe alternatives exist – you just need to know where to look. I’ve found great gluten-free options by:
- Choosing certified gluten-free brands
- Reading ingredient labels carefully
- Buying whole cuts of meat
- Making homemade versions of processed favorites
- Shopping at specialty meat counters
Keep in mind that price isn’t always an indicator of gluten content when it comes to processed meats.
Even premium brands might use wheat-based fillers.
Your best bet is to look for specifically labeled gluten-free options or stick to simple, unprocessed cuts of meat.
3. Salad Dressings and Marinades
Just when you think you’re making a healthy choice with a big salad, your dressing might be sneaking gluten onto your plate.
The culprits are the thickening agents and stabilizers that help give dressings their creamy texture.
After learning this hard, I’ve become much more careful about my salad toppings.
The thicker and creamier the dressing, the more likely it contains gluten-based thickeners.
This is especially true for “light” or “fat-free” versions, where manufacturers add extra stabilizers to compensate for the missing fat.
Most surprising gluten-containing dressings:
- Blue cheese (often uses wheat as a mold culture)
- Creamy Italian
- Some ranch dressings
- Many Asian-style dressings
The key problem lies in ingredients like modified food starch, malt vinegar, “natural flavors,” hydrolyzed vegetable protein, and emulsifiers.
Making your own dressing is surprisingly simple and gives you complete control over ingredients.
My go-to basic vinaigrette combines:
- Extra virgin olive oil
- Fresh lemon juice or balsamic vinegar
- Dijon mustard (check label for gluten-free)
- Fresh herbs
- Sea salt and pepper
For creamy dressings, I use Greek yogurt or mashed avocado as a base instead of commercial thickeners.
Not only are these alternatives gluten-free, but they also add extra nutrients to your meal.
If you prefer store-bought options, look for brands labeled “gluten-free.“
But remember, even then, it’s worth checking the ingredient list as formulations can change.
4. Imitation Seafood
Ever wondered what gives imitation crab its springy texture?
Unfortunately for gluten-sensitive folks, wheat protein is the secret ingredient.
When I first learned about surimi (the base for most imitation seafood), I was shocked to discover it often contains more wheat than fish.
SURPRISING FACT: Some imitation crab products can contain up to 50% wheat starch and protein! That’s why they’re sometimes referred to as “the hot dog of the sea.”
The manufacturing process of imitation seafood is quite revealing:
- Fish (usually Alaskan pollock) is ground into a paste
- Wheat starch and proteins are added as binders
- Food coloring creates that “crab-like” appearance
- Artificial and natural flavors simulate seafood taste
Common products to watch out for:
- California roll filling
- Seafood salad
- Fish sticks
- Seafood-flavored snacks
- Some fish cakes and patties
The good news? Real seafood alternatives are often more affordable than you might think:
- Canned chunk tuna for salads
- Fresh fish on sale (freeze for later)
- Real crab meat (check for seasonal deals)
- Sustainably caught fish options
- Frozen raw shrimp
It’s important to exercise caution when dining out, especially with certain dishes.
Be wary of sushi rolls that contain crab, as they may not always be prepared with fresh ingredients.
Similarly, seafood salads found at delis can sometimes raise concerns about their freshness and quality.
Asian dishes that include fish cake also warrant attention, as they might not meet your expectations.
Additionally, seafood pasta dishes can vary significantly in preparation and ingredients, so it’s wise to inquire further.
Lastly, be cautious with packaged seafood snacks, as they often contain preservatives and ingredients that may not be ideal.
By keeping these tips in mind, you can enhance your dining experience and make more informed choices.
5. Beverages
Think your drink is safe? Think again.
While plain water and juice are naturally gluten-free, many popular beverages surprisingly hide this problematic protein.
After discovering gluten in my favorite coffee drink, I learned to be more careful about what I sip.
Pre-made coffee drinks often contain barley-based ingredients or wheat-derived thickeners.
I once got glutened by a popular chain chocolate drink containing malt extract!
Let’s break down the risky drinks:
Malted Beverages:
- Traditional beer (made from barley)
- Malted milk drinks
- Some chocolate beverages
- “Energy” drinks with malt
- Instant breakfast drinks
Coffee Shop Hazards:
- Flavored syrups
- Powdered drink mixes
- Some coffee substitutes
- Blended frozen drinks
- Certain protein add-ins
Safe alternatives that I’ve discovered:
- Hard ciders
- Wine and distilled spirits
- Gluten-free beer (made from sorghum or rice)
- Plain coffee and tea
- Fresh-squeezed juices
- Sparkling water with natural flavors
The safest approach? Stick to simple beverages without added ingredients.
Ask for the ingredient list or syrup bottle to check yourself when in doubt.
At coffee shops, request unsweetened drinks and add certified gluten-free flavoring.
6. Soup Bases and Broths
That warming bowl of soup might not be as innocent as it seems.
Even clear broths often harbor hidden gluten, which is used as a flavoring agent or thickener.
This discovery completely changed how I approach both store-bought and restaurant soups.
What surprised me most was learning that even basic chicken broth can contain gluten as a flavor enhancer.
TIP: Many manufacturers use wheat-based ingredients to enhance flavor and add body to what would otherwise be a thin liquid. Always check labels, even on products labeled “natural” or “pure.”
The trouble with commercial broths goes beyond obvious additives.
Most cream-based soups use flour thickeners, while many clear broths contain hydrolyzed wheat protein for flavor enhancement.
Even vegetable soups might include barley or other grain-based ingredients.
What’s particularly challenging is that terms like “natural flavoring” can actually mean malt extract or other gluten-containing ingredients.
Common problematic ingredients include:
- Bouillon cubes (often contain wheat as a binder)
- Stock concentrates (can consist of malt flavoring)
- Yeast extract (sometimes grown on barley)
- “Natural flavors” (might be grain-derived)
I’ve found the safest approach is making my own broth in a slow cooker—it’s surprisingly easy and gives you complete control over ingredients.
When that’s not practical, I look for certified gluten-free boxed broths or trusted brands like Pacific Foods or Kettle & Fire (though I always verify current formulations).
When making broths and soups, start with whole ingredients and use cornstarch or arrowroot instead of flour for thickening.
Season with pure herbs and spices, but always verify that any added seasonings are gluten-free.
7. Candy and Chocolate
Your favorite candy bar might be hiding more than just calories.
I discovered this the hard way during Halloween when my “safe” chocolate triggered unexpected symptoms.
Gluten in candy isn’t always obvious – it can appear in everything from licorice to chocolate-covered nuts.
Pure, plain chocolate should be naturally gluten-free.
However, gluten risks increase significantly after adding flavorings or fillings.
I stick to certified gluten-free brands or plain dark chocolate from trusted manufacturers.
The most surprising sources of gluten in candy are malt and modified food starches.
Malt, derived from barley, adds a distinct flavor to many candies, while wheat-based ingredients often appear as thickeners or stabilizers.
Some manufacturers even dust their production lines with flour to prevent sticking.
Typical candies to watch out for:
- Licorice (wheat flour is a main ingredient)
- Malted milk balls
- Candy bars with cookie pieces
- Chocolate-covered pretzels
- Seasonal novelty candies
Cross-contamination is particularly tricky in candy production.
Many companies use the same equipment for gluten-containing and gluten-free products.
Even if a candy doesn’t directly contain gluten ingredients, shared manufacturing lines can make it unsafe for those with high sensitivity.
Safe alternatives have become increasingly available. Consider these naturally gluten-free treats:
- Simple dark chocolate or pure chocolate bars
- Fruit-based candies and gummies
- Pure maple candy
- Hard candies (check ingredients)
- Certified gluten-free specialty chocolates
Keep in mind that holiday and seasonal candies may have different formulations than regular ones.
Always check labels, even on products you’ve safely enjoyed before.
8. Seasoning Blends
When you think your simple herb blend is safe, those mysterious “anti-caking agents” and “natural flavors” on the label might tell a different story.
After getting unexpectedly glutened by a common taco seasoning, I learned that even our trusted spice blends need careful scrutiny.
SPICE SAFETY: Single-ingredient spices like pure cinnamon, basil, or oregano are naturally gluten-free. The risk comes with blends and mixes where manufacturers add fillers and anti-caking agents.
Common culprits in seasoning blends:
- Wheat-based starches as anti-caking agents
- Malt flavoring in barbecue blends
- Modified food starch in gravy mixes
- Wheat-derived “natural flavors”
- Flour as a thickening agent
The simplest solution? Create your own spice blends.
I keep these basic spices on hand and mix them as needed:
- Pure dried herbs
- Individual ground spices
- Certified gluten-free seasoning salts
- Pure garlic and onion powders
- Whole peppercorns
Cross-contamination is another concern, particularly with spices processed in facilities that also handle wheat products.
Even if a blend doesn’t contain gluten ingredients, shared equipment can make it unsafe for those with high sensitivity.
When buying pre-made seasonings, look for certified gluten-free labels and companies that specifically address allergen concerns in their manufacturing process.
The good news is that more companies are now producing certified gluten-free seasoning blends, making it easier to find safe options.
Just remember to recheck labels periodically, as formulations can change without notice.
9. Processed Cheese Products
Ever wonder why processed cheese slices have that perfect melt and never stick together?
The answer might surprise you – and concern those avoiding gluten.
My research discovered that many processed cheese products contain wheat-based ingredients as anti-caking agents and stabilizers.
Real, natural cheese is naturally gluten-free.
The problem starts when manufacturers process and modify cheese products with additives and stabilizers.
While natural cheddar, mozzarella, or brie are typically safe, processed cheese products often contain hidden gluten in various forms:
- Shredded cheese with anti-caking agents
- Spray cheese products
- American cheese slices
- Cheese spreads
- “Cheese food” products
The manufacturing process of processed cheese often involves wheat-based ingredients to:
- Prevent clumping
- Improve texture
- Extend shelf life
- Create uniform melting
- Reduce production costs
Your safest options are natural cheeses:
- Block cheese you grate yourself
- Fresh mozzarella
- Artisanal cheeses
- Plain cream cheese
- Natural aged cheeses
The key to avoiding gluten in cheese products is simplicity – the fewer ingredients, the better.
I’ve learned to buy blocks of natural cheese and grate them myself rather than risking pre-shredded varieties.
Not only does this ensure they’re gluten-free, but the flavor and melting qualities are superior, too.
10. Pickled Products
That tangy pickled cucumber might not be as innocent as it seems.
While exploring gluten-free eating, I discovered that the vinegar used in pickling can distinguish between a safe snack and an unexpected gluten exposure.
PICKLING TIP: When making your own pickles, use distilled white vinegar or apple cider vinegar. They’re naturally gluten-free and provide the perfect tangy flavor.
The main concern with pickled products centers around malt vinegar derived from barley and contains gluten. This vinegar appears in:
- Traditional British-style pickles
- Some commercial pickle brands
- Pickled onions
- Certain relish products
- Some pickled vegetables
Safe vinegars for pickling include:
- Distilled white vinegar
- Apple cider vinegar
- Rice vinegar
- Wine vinegar
- Balsamic vinegar
The pickling process itself is naturally gluten-free – it’s all about fermentation and acidity.
The problem comes from added ingredients and processing methods.
Some manufacturers might use wheat-based ingredients as preservatives or flavor enhancers, even in products that traditionally don’t need them.
Making your own pickled vegetables is surprisingly simple and gives you complete control over ingredients.
Start with fresh vegetables, safe vinegar, salt, and your choice of spices.
Not only will you avoid gluten, but you’ll also get better flavor and crunch than store-bought versions.
When buying commercial pickled products, look for labels specifically stating “gluten-free” or check the vinegar type listed in the ingredients.
11. Natural Flavorings
Remember when I thought “natural flavoring” meant safe?
That was before I learned these supposedly natural ingredients often harbor hidden gluten sources.
What seems like a simple ingredient on the label can actually be a complex mixture of compounds, some derived from grain-based sources.
LABEL REALITY: The term “natural flavoring” can legally include dozens of ingredients, including gluten-containing grain extracts. I’ve learned to treat this term as a red flag unless verified gluten-free.
What makes natural flavorings tricky is their complexity. A single “natural flavor” might contain:
- Grain-based carriers
- Barley or malt extracts
- Wheat-derived ingredients
- Fermentation byproducts
- Modified starches
Everyday products often conceal questionable natural flavors, particularly in beverages and drink mixes, where the labels may not reveal what’s really inside.
Snack foods are another common culprit, frequently containing ambiguous flavorings that can mislead consumers.
Similarly, seasoning blends may harbor these elusive ingredients, impacting the overall taste without clear disclosure.
Prepared sauces, too, often include natural flavors that can obscure their true contents.
Lastly, dairy products are not exempt from this practice, making it essential for consumers to be vigilant about what they’re purchasing and consuming.
How do we verify safety? Here’s my three-step approach:
- Look for certified gluten-free labels
- Contact manufacturers directly
- Choose products with simple, clean ingredients
The safest approach is to favor products that use real ingredients instead of “natural flavors.”
For example, choose vanilla extract over “natural vanilla flavor” or real herbs instead of “natural herb flavoring.”
When in doubt, reach out to manufacturers – reputable companies usually have detailed allergen information readily available.
Remember: Even if a product was safe before, formulations can change.
Make a habit of rechecking labels periodically, especially on your regular purchases.
Your best defense is staying informed and choosing products with transparent ingredient lists.
Gluten-Free Alternatives and Solutions
Discovering you must avoid gluten doesn’t mean giving up your favorite foods.
Successful gluten-free living is less about finding exact replacements and more about discovering new, delicious alternatives.
Direct Substitutes
Finding good gluten-free versions of traditional products can feel like a treasure hunt.
The key is understanding that not all alternatives are created equal – some are worth the premium price, while others might leave you disappointed.
SHOPPING TIP: Start with highly rated brands before giving up on a particular substitute. My early experiences with cardboard-like bread almost made me quit trying until I discovered several brands that actually taste great.
Quality Factors to Consider:
- Texture (essential for breads)
- Taste without artificial aftertaste
- How well it performs in recipes
- Shelf life and storage needs
- Nutritional value
Top-performing brands I’ve discovered:
- Breads: Canyon Bakehouse, Schar
- Pasta: Jovial, Tinkyada
- Crackers: Simple Mills, Mary’s Gone Crackers
- Flour blends: Cup4Cup, Bob’s Red Mill 1-to-1
Making Better Choices
Sometimes, the best approach isn’t finding an exact replacement but rethinking the dish entirely.
I’ve found many natural alternatives that are not just “good enough” but actually preferable to their gluten-containing counterparts.
Smart Substitution Strategies:
- Use lettuce wraps instead of bread
- Try zucchini noodles for pasta dishes
- Replace breadcrumbs with ground nuts
- Swap flour tortillas for corn versions
- Use portobello mushrooms as burger buns
Shopping tips that save money:
- Focus on naturally gluten-free whole foods
- Buy in bulk when you find products you trust
- Compare prices across multiple stores
- Watch for sales and stock up
- Join store loyalty programs for discounts
The most successful approach I’ve found combines both direct substitutes and natural alternatives.
For example, while I keep good gluten-free bread on hand for occasional sandwiches, I’ve mostly shifted to protein-based lunches that don’t need bread at all.
Remember that transitioning to gluten-free eating is a journey, not a race.
Take time to experiment with different products and approaches.
What works for one person might not work for another, so be patient as you discover your preferences and favorites.
Most importantly, focus on what you can eat rather than what you can’t.
A gluten-free diet can be abundant, delicious, and satisfying when approached with creativity and an open mind.
