Happy Meal toys and other promotions that come with high-calorie children's meals will soon be banned in parts of Santa Clara County unless the restaurants meet nutritional guidelines approved Tuesday by the county Board of Supervisors.

"This ordinance prevents restaurants from preying on children's' love of toys" to sell high-calorie, unhealthful food, said Supervisor Ken Yeager, who sponsored the measure. "This ordinance breaks the link between unhealthy food and prizes."
