個案詢問護理師纖維素的好處。下列敘述何者正確？
A client asks the nurse about the benefits of fiber. Which statement is correct?
- AFiber replacement is necessary for everyone每個人都有必要補充纖維
- BFiber should be increased rapidly to prevent gas應快速增加纖維攝取以預防脹氣
- CFiber slows digestion, causing prolonged fullness✓ 正解纖維減緩消化，導致飽足感持續較久
- DFiber is a primary source of caloric energy纖維是熱量的主要來源
膳食纖維（Fiber）對健康有多重益處。水溶性纖維在腸道中會吸收水分形成膠狀物質，進而減緩胃排空速度，這不僅能增加飽足感，還能平緩餐後血糖上升。攝取纖維應循序漸進，以避免脹氣與腹痛。纖維本身不具熱量，不屬於能量來源，且並非所有人都需額外補充，應優先從天然飲食中獲取。護理師的角色是提供正確營養衛教，鼓勵攝取原型食物。
Dietary fiber confers many health benefits. Soluble fiber absorbs water in the intestines to form a gel-like substance that slows gastric emptying, increases satiety, and blunts postprandial blood glucose rises. Fiber intake should be increased gradually to avoid bloating and abdominal pain. Fiber itself provides no calories and is not a source of energy, and not everyone requires additional supplementation; whenever possible, fiber should be obtained from natural foods. The nurse's role is to provide accurate nutritional teaching and to encourage consumption of whole, unprocessed foods.
