The best source of insoluble fiber among the options provided is pears with skin. Insoluble fiber is found in foods that have a high cellulose content, which helps promote bowel regularity and prevent constipation by adding bulk to the stool. The skin of pears is particularly rich in this type of fiber, making it an excellent choice for someone looking to increase their intake. Oatmeal, while a great source of soluble fiber, does not significantly contribute to insoluble fiber. White rice lacks fiber altogether, particularly if it is refined, and yogurt does not provide substantial fiber content. Thus, pears with skin are the most beneficial option for enhancing insoluble fiber intake in the diet to support digestive health.
