题目

阅读理解    A big bowl of milk can be a great way to start the day. Many snack bars contain nutrients that help our bodies stay strong and healthy. But some of these foods are packed with too many vitamins and minerals. According to a new study by the Environmental Working Group (EWG), this extra fortification may be more harmful than helpful.    Of the tested snack bars, 27 have more than 50% of the recommended amounts of vitamin A, niacin and zinc. Nutrition facts listed on packages are based on recommended daily values for adults, who are physically larger and require more vitamins and minerals. So when kids eat these cereals (麦片) and snack bars, they are getting more nutrients than they need.    Vitamin A, niacin (烟酸) and zinc (锌) are best in fresh and unprocessed foods that are in their natural state. Vitamin A helps you see at night. It occurs naturally in eggs, meat and carrots. Niacin is a vitamin that helps our bodies make energy. It is found in foods like fish, seeds, and peanuts, as well as in whole grains like wheat and brown rice. Zinc helps our bodies fight off infection. It is found in many foods, including wheat-based products, meats, beans and nuts.    Children typically eat more than one serving of cereal or snack bars a day, in addition to taking vitamin supplements. Eating large amounts of these nutrients can be dangerous to kids' health. Too much vitamin A can cause liver damage, and high levels of zinc can destroy the body's natural immunity, or power to fight infection.    The EWG authors are calling for the FDA to make changes to its guidelines for nutrient intake and revise its daily values to match kids' diets. （1） What can we infer from the second paragraph ?.
