Passage One
How much do you know about nutrition? If your knowledge is similar to that of food shoppers who answered three surveys for the U. S. Food and Drug Administration, then you probably share some wide-spread misinformation about nutrition. Check your answers to the following statements. Is it true or false?
Statement 1: Fresh vegetables cooked at home are always more nutritious than canned or frozen vegetables. False. The nutritional difference depends more on how vegetables are handled or prepared than in whether they are bought fresh or packaged. Overcooking, for example, destroys many nutrients. Vegetables cooked in too much water can lose a significant amount of vitamins.
Statement 2: When dieting, avoid starchy(淀粉类) foods, such as bread or potatoes. False. If you cut out starchy foods, such as peas, potatoes, bread, and rice, you cut out very good sources of several B vitamins, Vitamin C, and other nutrients. Moreover, ounce for ounce, bread and potatoes have fewer calories than sirloin steak and roast beef.
Statement 3: Taking extra vitamins beyond the recommended daily allowances won’t give you more energy. True. It’s widely believed that extra vitamins provide more energy. But taking more than the body needs doesn't make it function better, just as overfilling your gas tank doesn’t make your car run faster.
If you answered these questions correctly, you can for the time being consider yourself well informed about food and nutrition by today’s standards. But remember that nutrition is a complex and growing science and that today’s beliefs may be changed as new information becomes available.

【正确答案】：B
【名师解析】:文章通过一系列关于营养知识的陈述，旨在测试读者的营养知识水平。文章内容涉及对常见营养误区的纠正，如烹饪方式对蔬菜营养的影响、饮食中淀粉类食物的作用以及过量补充维生素的问题。因此，文章的核心在于测试和提升读者的营养知识。 选项A“有效减肥的小贴士”虽然与营养有关，但并未涵盖文章的全部内容，故不合适。 选项B“测试你的营养智商”准确概括了文章的主旨，即通过一系列问题测试读者的营养知识。 选项C“营养：一门复杂的科学分支”虽然正确，但过于宽泛，未能突出文章的测试性质。 选项D“误导性的营养观念”虽然与文章内容相关，但同样未能准确概括文章的主旨。 综上所述，选项B“测试你的营养智商”是最合适的标题。
