Although their original food customs may have been nutritionally adequate, their new environment may cause them to change their eating habits. For example, if milk was a staple (basic) food in their diet before moving and is unusually expensive in the new environment, milk may be replaced by a cheaper, nutritionally inferior beverage such as soda, coffee, or tea. Candy, possibly a luxury in their former environment, may be inexpensive. As a result, a family might increase consumption of soda or candy and reduce purchases of more nutritious foods. Someone who is not familiar with the nutritive value of foods can easily make such mistakes in food selection.
