A meal pattern is a tool used to develop menus for specific age groups that includes foods from four food groups: meat/protein, vegetables/fruits, grains, and dairy. Patterns can incorporate standards for sodium, fat, saturated fat, and cholesterol levels set by state agencies. There are different types of menus including a la carte which lists individually priced items, table d'hote which is a fixed price multi-course menu, function menus for special events, and cycle menus which rotate on a weekly or multi-week basis.
