Gluten-free refers to any food or diet that doesn’t contain gluten.

Gluten is a protein naturally found in many grains, like wheat, barley, and rye. Some oats may also contain gluten. Food can maintain their shape through the use of gluten, acting as the sticky glue that keeps food together.

Gluten has several health benefits, but it’s also for health reasons that people go gluten-free. For example, there are people with celiac disease, an autoimmune disorder where the lining of the small intestine gets damaged from gluten intake. There are also those with non-celiac gluten sensitivity, which causes abdominal pain, diarrhea, and bloating.

Another autoimmune disorder, gluten ataxia, can affect nerve tissues and muscles. There’s also a chance you may have a wheat allergy, which leads to a complication with gluten.

Due to these disorders, you may need to start a gluten-free diet. Corn starch, as a general staple, may be one of your concerns.
