　　Don't we all know a"Happy Meal"when we see one-the famous boxed meal that includes a hamburger，a kid-sized portion of fries，a drink and so on，served with a toy that's extremely popular with children who love to collect them？

　　But collectors of these little toys will soon be in for a surprise．For the book lovers though，there is some good news．McDonalds will replace toys with books．However，each of these books will mainly pass on nutritional messages．

　　Do you know that McDonalds has been marketing the boxed kid's meal since 1979？Happy Meals are extremely popular with kids，especially for its collectible toys，when you consider that over 1.3billion of these packages are sold each year!These packages have been very controversial．Health supporters believe that drawing kids to these meals with toys is a clever way of promoting unhealthy food choices．They see it as an advertising strategy of"catching its customers young"-a move that has paid off very well for the fast food company．

　　Child development experts say that food habits get formed in children by age six and continue through to their adult life．Fatty and sugary foods such as those served in McDonalds'Happy Meals are believed to play a big role in growing health problems such as obesity and diabetes．Public health care costs have gone up and untold amounts of other health problems．In 2010，the State of California tried to ban toys in Happy Meals．But it was strongly opposed by some as being heavy-handed，and the ban was thrown out by the government．

　　While some people believe that McDonalds，with its large following of children，can create a powerful message through the books，others believe its actions are contradictory．Anyway，the company is trying to spread the message of nutrition while it is serving food that is anything but healthy．
