Gluten-Free Ingredient Scanner: The Label Detective
Living with Celiac Disease or Non-Celiac Gluten Sensitivity (NCGS) requires hyper-vigilance. Label reading is a skill, but manufacturers often hide gluten behind vague names like "Natural Flavors" or "Modified Starch." Use this tool to instantly scan ingredient lists for the "Red Flag" terms that standard checks might miss.
Enter ingredients separated by commas or list them one per line. Our tool will scan for gluten-containing grains, malt products, and hidden gluten additives.

Beyond the Grain: The 3 Levels of Inspection
A nutritionist doesn't just look for "Wheat." To stay strictly gluten-free, you must evaluate products on a safety hierarchy:
- Level 1: The "Certified" Gold Standard. Look for the GFCO or similar third-party seals. These products are tested to contain less than 10ppm (parts per million) of gluten, which is stricter than the FDA's 20ppm standard.
- Level 2: The "Naturally Gluten-Free" (But Risky). Grains like Oats, Corn, and Rice are naturally safe, but highly susceptible to Cross-Contact during farming. Unless they are labeled "Gluten-Free," assume they have been processed on shared wheat equipment.
- Level 3: The "Hidden" Chemistry. Ingredients like Maltodextrin (usually corn, but sometimes wheat), Brewer's Yeast (byproduct of beer), and Hydrolyzed Vegetable Protein (HVP) are common camouflages for gluten. This scanner helps you catch these Level 3 threats.
Strategic Scenario: The "Wheat-Free" Trap
One of the most dangerous marketing terms in the grocery store is "Wheat-Free." It is NOT the same as Gluten-Free. Consider these two products:
Scenario A: The "Spelt Sourdough"
- Label Claim: "Wheat-Free! Organic!"
- Ingredients: Spelt Flour, Water, Salt.
- The Verdict: UNSAFE. Spelt is an ancient cousin of wheat. It is technically "Wheat-Free" by modern taxonomy, but it is 100% full of gluten. A Celiac would react violently to this.
Scenario B: The "Gluten-Free" Tamari
- Label Claim: "Certified Gluten-Free."
- Ingredients: Water, Soybeans, Salt, Alcohol.
- The Verdict: SAFE. Traditional Soy Sauce is fermented with wheat. Tamari is typically fermented with soybeans only. The "Certified" label confirms it meets the <20ppm safety threshold.
Labeling Loopholes & Safety FAQs
Q: What does "May Contain Wheat" really mean?
A: This is a voluntary "Cross-Contact" statement. It means the product shares a factory line with wheat products. While some people with mild sensitivity ignore it, Celiacs should strictly avoid these products, as "dust" contamination often exceeds safe limits.
Q: Are Oats safe?
A: Only if labeled "Certified Gluten-Free." Standard oats are grown in fields next to wheat and are almost guaranteed to be contaminated. Furthermore, a small percentage of Celiacs react to Avenin, a protein in oats that mimics gluten, even if the oats are pure.
Q: Is Maltodextrin gluten-free?
A: Usually, yes. In the US, it is almost always made from corn, rice, or potato. If it is made from wheat, the FDA requires the label to explicitly say "Maltodextrin (Wheat)." If you see plain "Maltodextrin," it is generally considered safe.
Q: Is yeast gluten-free?
A: Baker's Yeast and Nutritional Yeast are naturally gluten-free. However, Brewer's Yeast is a byproduct of beer (barley) making and contains gluten. Always check the source.
Q: Can I trust "Natural Flavors"?
A: Proceed with caution. While US law requires 'Wheat' to be listed, Barley (malt) is not considered a top allergen and can hide legally under 'Natural Flavors.' Unless the product is Certified Gluten-Free, there is a risk of hidden barley-derived gluten.
