Ever felt bloated or sluggish after eating bread or pasta? Gluten — a protein in wheat, barley, rye, and triticale — could be the reason. Eliminating gluten isn’t something everyone needs to do, but for people with celiac disease or non-celiac gluten sensitivity (NCGS), gluten can cause bloating, abdominal discomfort, diarrhea, inflammation, and even long-term intestinal damage.
