The term "high-fiber diet" refers to a diet that contains an adequate amount of dietary fiber. Fiber is a type of carbohydrate found in plant foods such as fruits, vegetables, legumes, and whole grains. It is essential for maintaining good health because it helps regulate the digestive system by promoting regular bowel movements, reducing constipation, and preventing diverticulitis. A high-fiber diet can also help lower cholesterol levels, control blood sugar levels, and promote weight loss by making you feel full for longer periods of time. Therefore, consuming a "high-fiber" diet is important for maintaining overall health and wellness.
