(单选题)

It is suggested in the dietary guidelines that ______.

A.six leading cause of death might be linked to diet

B.fat and alcohol should be taken as little as possible

C.eating diverse foods helps maintain proper weight

D.sugar and salt should be taken in restricted amount

参考答案：D

参考解析：

推理判断题。原文只在第一段最后一句提到关于dietary guidelines的信息，D是对该句句末部分的近义改写，故为本题答案。A项是第一段倒数第二句中提到的U.S. Senate committee on nutrition的意见，并非dietary guidelines的内容；B项所说的as little as possible与原文第一段最后一句句末提到的limit不符，因此不正确；C项的eating diverse foods和maintain proper weight在该段最后一句都有提及，但它们都是dietary guidelines的建议，属于并列关系，故不正确。故选D。
