Dietary fiber is a food component that is not digested in the small intestine but utilized in the large intestine. It is primarily involved in intestinal health by increasing stool volume for those concerned about bowel movements and serving as food for intestinal bacteria such as good bacteria. Furthermore, its relationship with postprandial blood glucose levels has been recognized, making it an essential component for health maintenance.

According to the "Dietary Reference Intakes for Japanese (2025)," adults and the elderly "should consume at least 25g of dietary fiber per day."
