Which sentence gives evidence to support the main idea that ads for junk food are bad for children? The advertising industry spends billions of dollars every year on ads targeted toward children. Many of these ads promote junk foods, which lead to weight gain among children. A World Health Organization report shows that junk food ads harm children’s health. The only way to prevent kids from eating large amounts of unhealthy food is to strengthen laws that control advertisers. Some countries like Sweden have already taken steps to protect children from such ads. But controlling these ads on the Internet and other places may prove to be a big challenge. So, the final responsibility to protect children falls with their parents. Children need to be educated and guided to make healthy food choices.
