The phrase "more dietary fiber" refers to consuming an increased amount of dietary fiber in one's daily diet. Dietary fiber is a type of carbohydrate that is found naturally in many foods, particularly those containing plant-based ingredients such as fruits, vegetables, and whole grains. It is essential for maintaining good health because it helps to regulate the digestive system by promoting regular bowel movements and preventing constipation. Consuming more dietary fiber can also help with weight management, as it makes you feel fuller for longer periods of time, reducing your overall caloric intake.
