Why did McDonald not need to be responsible for the health problem of overweight children?

A court in the United States has ruled that the hamburger chain McDonald’s was not responsible for the health problem of overweight children who eat at its restaurants. The judge said lawyers acting for the children had failed to show that McDonald’s products presented a danger unknown to consumers. This is the first case of its kind to go through the American courts. The outcome is a victory for the fast food industry, which is braced for a wave of tobacco-style litigation over the health consequences of poor diet. The action was mounted on behalf of a group of overweight children suffering from diabetes, high blood pressure and other diet-related ailments. They blamed their problems on the fat laden hamburgers and chips they’d regularly eaten at McDonald’s restaurants in New York.
