Recently the FDA set an official standard for gluten free labeling. Officially for anything to be labeled gluten free it must contain less than twenty parts per million of gluten. This is a big victory for anyone with gluten intolerance or celiac disease as having even the smallest amount of gluten could be extremely harmful. Without these standards set by the FDA brands could recklessly slap a gluten free label on anything they wanted without any concern for those they may harm, lucky for us coconut oil is a naturally gluten free product.
If you already are gluten free, or are planning on going gluten free, we have an awesome cheat sheet from Simply Gluten Free Magazine (see the picture) that list all of the foods that are safe to eat along with unsafe foods, foods that commonly contain gluten, and foods that may or may not contain gluten. I know I found this picture very helpful in understanding what it means to have a gluten free diet.
