Why I Pay Close Attention to Gluten in My Practice

Baked goods made with wheat flour are the obvious sources of gluten. The tricky part — the part that trips up even careful parents — is that gluten is widely used as an additive to modify the texture, flavor, and moisture of processed foods. It’s a binder, a thickener, and a filler, which means it shows up in products you’d never suspect.

For most children, wheat is perfectly fine. But for kids with celiac disease, a diagnosed wheat allergy, or non-celiac gluten sensitivity, even small hidden amounts matter. And in my experience with children who have persistent eczema, allergies, or asthma, a carefully supervised look at gluten is sometimes a useful piece of the puzzle — always alongside, never instead of, proper allergy testing.

What Is Gluten, Exactly?

Gluten is the general term for a group of proteins found in certain grains — primarily barley, rye, and wheat. In nature, these proteins help seeds germinate. In the kitchen, they give bread its stretch and chew.

The gluten-containing grains to know are wheat (including all its cousins — durum, semolina, spelt, farro, kamut, einkorn, emmer), barley, rye, and triticale. Oats are naturally gluten-free but are frequently cross-contaminated during processing, so look for certified gluten-free oats.

The Alternative Names for Gluten (What to Scan Labels For)

Don’t see "wheat," "barley," or "rye" on the label? Gluten may still be there under a different name. Here’s the list I give families:

• Wheat varieties and derivatives: Bulgur, club wheat, couscous, durum, einkorn, emmer, farina, farro, freekeh, graham, Kamut, semolina, spelt, sprouted wheat, wheat berries, wheat protein isolate, wheat bran hydrolysate, wheat germ oil, wheat grass, vital wheat gluten
• Processed forms: Bread crumbs, cracker meal, cereal extract, hydrolyzed wheat protein, seitan, brewer’s yeast, vegetable protein
• Malt in all its forms: Malt extract, malt flavoring, malt syrup, malt vinegar
• Starches (when wheat-derived): Gelatinized starch, modified starch, modified food starch, vegetable starch
• Flour, in all its guises: All-purpose, bread, cake, high-gluten, high-protein, instant, pastry, self-rising, soft wheat, steel-ground, stone-ground, whole wheat

Where Gluten Hides in Everyday Foods

These are the sneaky sources that catch parents off guard:

• Soy sauce — most brands are made with wheat (choose tamari or coconut aminos instead)
• Salad dressings and marinades — malt vinegar, soy sauce, and wheat-based thickeners are common
• Cream-based soups — flour is a classic thickener
• Processed and deli meats, sausages — gluten is used as a binder or filler
• French fries — battered, or fried in shared oil with breaded foods
• Flavored potato and corn chips — seasonings may contain wheat proteins
• Marshmallows, licorice, and packaged candy — often dusted or bound with wheat
• Gravies, canned soups, and seasoned rice mixes
• Brown rice syrup — sometimes processed with barley enzymes

And beyond food entirely: alcohol (beer and malt beverages), art supplies like some Play-Doh (contains wheat), cosmetics and personal care products (used as a binder), and medications and supplements (wheat starch is a common inactive ingredient). For a child with true celiac disease, these non-food sources genuinely matter.

How to Read a Nutrition Label for Gluten in Under a Minute

1. Check the "Contains" statement first. U. S. law requires wheat to be declared here. If it says "Contains: Wheat," you have your answer immediately.
2. Scan the ingredient list for the alternative names above — especially malt, semolina, and anything with "wheat" buried inside it.
3. Look for a certified gluten-free seal if your child needs strict avoidance. "Gluten-free" on a U. S. label legally means under 20 parts per million.
4. Remember that barley and rye are NOT required to be highlighted the way wheat is — so malt (from barley) can appear without a warning. This is the single most common miss I see.

Simple Gluten-Free Swaps That Actually Work

Going gluten-free doesn’t have to mean expensive specialty products. Here are the everyday swaps I recommend:

• All-purpose flour → Almond flour, oat flour, or all-purpose gluten-free flour
• Breaded or battered chicken → Baked or grilled chicken
• Couscous → Quinoa
• Flour tortillas → Corn tortillas
• Orzo → Brown rice
• Wheat pasta → Rice or chickpea pasta
• Bottled salad dressing → Simple homemade vinaigrette (oil, vinegar, seasoning)
• Soy sauce → Tamari or coconut aminos
• Wheat crackers → Rice crackers (plain varieties)
• Whole wheat bread → Certified gluten-free bread

A helpful mindset: naturally gluten-free whole foods — plain fruits, vegetables, rice, quinoa, beans, eggs, plain meats, nuts, and seeds — are always the safest and most nutritious foundation. The more of your child’s plate that comes from these, the less label-reading you have to do.

A Word of Caution on Gluten-Free Processed Foods

Here’s something I remind parents of often: "gluten-free" does not automatically mean "healthy." Because gluten provides structure, manufacturers often replace it with emulsifiers, gums, cheap vegetable oils, extra sugar (under names like invert sugar, glucose syrup, or "natural flavor"), and refined starches. A gluten-free cookie is still a cookie. Read the full label, not just the front-of-package claim.

Should You Put Your Child on a Gluten-Free Diet?

This is where I want to be direct and evidence-based: do not remove gluten before talking to your pediatrician — especially if you haven’t ruled out celiac disease. Celiac testing is only accurate while your child is still eating gluten. If you remove it first, you can get a false-negative result and miss a lifelong diagnosis that matters enormously.

For children without celiac or a wheat allergy, some families report improvements in skin, digestion, or energy on a cleaner, lower-processed diet — but it’s important to identify whether it’s the gluten specifically or the overall reduction in ultra-processed food doing the work. That’s a question I love working through with families individually, because the answer guides everything that comes next.
