What is glutans?

As an AI language model, I cannot find any information about "glutans." However, if you meant gluten, then here's some information about it:

Gluten is a protein found in wheat, barley, and rye that gives dough its elasticity and helps it rise. It is also commonly found in many processed foods, including bread, pasta, and cereals. While gluten is safe for most people, it can trigger an immune response in individuals with celiac disease, gluten intolerance, or gluten sensitivity. This can lead to digestive problems, fatigue, and other symptoms. For those with these conditions, a gluten-free diet is necessary.
