Oat Milk Have Gluten?

When asking whether oat milk has gluten, it’s crucial to know that oats are naturally gluten-free. However, they can be contaminated with gluten during the processing, growing, or transportation phases. This contamination typically occurs when oats come into contact with wheat, barley, or rye, which contain gluten.

Factors influencing gluten content in oat milk

  1. Manufacturing process: If the oat milk is produced in a facility that also processes gluten-containing grains, there’s a risk of cross-contamination. Some manufacturers take precautions to ensure their products are gluten-free, while others don’t.
  2. Certification: To be confident that your oat milk is gluten-free, look for a certified gluten-free label. This certification ensures that the product has been tested and contains less than 20 parts per million (ppm) of gluten, which is the threshold for gluten-free products.
  3. Ingredients: Be mindful of any additives in your oat milk, as some ingredients may contain gluten. Always read the ingredient list and be cautious of products with vague terms like “natural flavors” or “spices.”
