一位病人接受腸道手術後醫囑清流質飲食。下列哪種食物符合此飲食限制？

清流質飲食的定義為在體溫下呈液態且透明可透光的食物。蘋果汁為典型符合要求的選項。牛奶、奶油濃湯與優格皆屬於全流質（Full liquid diet），因含有脂肪或蛋白質顆粒，不符合清流質的定義，會延誤術後腸道功能的恢復評估。

A clear liquid diet consists of fluids that are transparent and liquid at room temperature, allowing apple juice to be an appropriate choice. Items like cream soup, vanilla yogurt, and milk are opaque or contain particles, classifying them as full liquids rather than clear liquids. Clear liquids are typically prescribed post-operatively to maintain hydration while minimizing gastrointestinal workload.

台美飲食分類大致相同，清流質飲食在台灣術後營養衛教中極為常見。
