Why do people prefer to eat chapatis made of unsieved wheat flour?

People generally prefer chapatis made of sieved wheat flour, not unsieved wheat flour. Sieved flour is considered better for making chapatis because it has a finer texture and produces softer chapatis. Unsieved flour, also known as whole-wheat flour or atta, has a higher fiber content and a more rustic texture, which some people may find less desirable in chapatis.
