Nationally representative surveys of food intake in U.S. children show large increases in snacking between the 1989-91 to 1994-98 and 1994-98 to 2003-06 periods. Childhood snacking trends are moving toward three snacks per day, and more than 27 percent of children's daily calories are coming from snacks. The largest increases have been in salty snacks and candy. Desserts and sweetened beverages remain the major sources of calories from snacks.
