Oat milk, a popular plant-based milk alternative, has gained significant attention in recent years due to its creamy texture and environmentally friendly production process. However, one of the most common concerns surrounding oat milk is whether it contains gluten, a protein found in certain grains that can cause adverse reactions in individuals with gluten intolerance or celiac disease. In this article, we will delve into the world of oat milk and explore its gluten content, providing you with a comprehensive understanding of this topic.
Understanding Oat Milk and Gluten

Oat milk is made by soaking oats in water and then blending them with water, creating a milky liquid that can be strained to remove the oats. The resulting liquid is oat milk, which can be flavored, sweetened, and fortified with various nutrients. The primary concern regarding oat milk and gluten lies in the fact that oats are often processed in facilities that also handle gluten-containing grains, such as wheat, barley, and rye. This can lead to cross-contamination, where small amounts of gluten may be introduced into the oat milk.
Gluten Content in Oat Milk
The gluten content in oat milk can vary depending on the production process and the type of oats used. Some oat milks may contain small amounts of gluten due to cross-contamination, while others may be gluten-free. According to the Celiac Disease Foundation, oats are naturally gluten-free, but they can be contaminated with gluten during processing. The Food and Drug Administration (FDA) regulates the labeling of gluten-free products, including oat milk, and requires that they contain less than 20 parts per million (ppm) of gluten.
| Brand | Gluten Content (ppm) |
|---|---|
| Oatly | <5 ppm |
| Califia Farms | <5 ppm |
| So Delicious | <10 ppm |
