答案与题解：
1．C 短文开头第一句就说，“吃土豆有益于肠道健康，而且对整个免疫系统也有益，尤其是吃土豆色拉或凉吃”，因此在四个选项中最有营养的非C项莫属。
2．A 第二段第三句说，“淋巴细胞水平低显示炎症水平下降”，故其他B、C、D三个选项均不正确。
3．B 第二段第二句引用了研究组负责人自己的话说，“在实验中使用未经加丁的土豆淀粉，就是为了模拟富含耐久淀粉的饮食所起的作用”，其他A、C、D三个选项文章均没有提及。
4．D 第四段第一句列出了一些富含耐久淀粉的食品，其中就没有D项“蔬菜”，而且实际上蔬菜也不是富含淀粉的食物。
5．D 第四段倒数第二句已经解释了耐久淀粉的特点：“不能在小肠中消化，而是分流到大肠，在大肠中发酵”。其他选项个别词语虽在短文中出现过，但都不是说明耐久淀粉的
