Dietary fiber content refers to the amount or level of dietary fibers present in a food item. Fibers are essential nutrients that aid digestion, help maintain bowel regularity and can also contribute to feelings of fullness after eating. The recommended daily intake of dietary fiber varies depending on age, sex, and other factors but is generally around 25-30 grams per day for adults. Foods that are high in dietary fibers include fruits, vegetables, whole grains, legumes, nuts, and seeds.
