Foods to Absolutely Avoid if You Suspect Gluten Sensitivity or Celiac Disease

43. Multivitamins & Protein Powders: Wellness with a Side of Wheat

That daily supplement or post-workout shake might be undermining your health goals. Some multivitamins and protein powders—especially those labeled as “plant-based” or “meal replacements”—use wheat-based fillers, binders, or flavorings like malt extract. Even natural flavorings can be derived from gluten-containing grains. Worse, some protein powders are manufactured in facilities that also handle wheat, raising cross-contamination risks. Always check for certified gluten-free labels and scan for hidden terms like “hydrolyzed wheat protein” or “wheat germ.” Don’t let your recovery shake or wellness routine secretly trigger the very inflammation you’re trying to avoid.

44. Instant Oatmeal Packets: Morning Minefields

Oats are naturally gluten-free—but most instant oatmeal packets are not. Many include flavorings, thickeners, or stabilizers derived from wheat or barley. Even oats labeled as “whole grain” can be cross-contaminated during processing unless certified gluten-free. Add to that flavored varieties like “maple & brown sugar” or “apple cinnamon,” which often contain malt extract or wheat starch for texture, and your safe breakfast just got risky. For peace of mind, stick to certified gluten-free oats and flavor them yourself with real fruit, cinnamon, or honey. Breakfast should fuel your day—not flare your symptoms.
