護理師教導個案纖維質的重要性。應強調哪些好處？

- ACauses constipation導致便秘

- DPromotes regular bowel movements✓ 正解促進規律排便
膳食纖維（Dietary Fiber）在人體消化道中無法被吸收，但具有關鍵的生理功能。它能增加糞便體積並吸收水分，使糞便軟化並刺激腸道蠕動，從而預防便秘。此外，纖維能減緩碳水化合物的吸收速度，有助於穩定血糖，並與膽酸結合促進排泄，有助於降低膽固醇與大腸癌的風險。護理師應教導個案透過攝取全穀類、蔬菜與水果來補充纖維。
Dietary fiber is not absorbed in the human digestive tract but has critical physiological functions. It adds bulk to stool and absorbs water, softening the stool and stimulating intestinal peristalsis to prevent constipation. In addition, fiber slows the absorption of carbohydrates, helping to stabilize blood glucose, and binds bile acids to promote their excretion, which may help lower cholesterol and reduce colon cancer risk. The nurse should teach the client to obtain fiber through whole grains, vegetables, and fruits.
