Question

   Imagine you are a kid living in America in 1920,and your parents are too busy to cook dinner. Instead,they serve you something they are sure is just as healthy as chicken and vegetables: a chocolate bar.36 However,as recently as the 1940s,many Americans believed that candy was as nutritious as an entire meal. Today,we understand that some foods are better for us than others. You probably know that the oatmeal(燕麦粥) and fruit you wisely ate for breakfast were packed with vitamins and other nutrients. You probably know as well that those chewy candies hidden in your drawer are little more than sugar. 37

   Back in the early 1900s,the science of nutrition — the study of how foods affect the body — was new. 38 But the importance of vitamins was not well understood. Many scientists believed that candy was just as healthful as steak and potatoes or fish and broccoli. 39 Ads for Milky Way suggested that each bar contained a glass of milk (not true) . There was even a popular candy bar called Chicken Dinner (which,thankfully,did not contain chicken) .

   Today,we know the dangers of eating too much sugar. We also have laws that prohibit companies from creating advertisements that lie about products.

40 But most of us understand it's best left for dessert.

   A. It sounds a little crazy now.

   B. We still love candy,of course.

   C. They are still made in a Boston factory.

   D. People knew that food provided energy.

   E. Candy companies wanted people to believe this too.

   F. Even little kids understand that eating too much sugar is unhealthy.

   G. Candy makers have continued to produce new kinds of candies to delight us.
