Olestra is different from ordinary fats in that___________.A、it prevents excessive intake of vitamins
B、it helps reduce the incidence of heart disease
C、it facilitates the absorption of vitamins by the body
D、it passes through the intestines without being absorbed
【正确答案】：D
【题目解析】：题目问的是食物油脂替代品和普通的脂肪有什么不同。根据第六段的第二句话It just slides through the intestines without being broken down.可知，食物油脂替代品滑过肠而不能被分解，因此选择D. it passes through the intestines without being absorbed（食物油脂替代品经肠而不被吸收）。
