can pregnant women eat heath bar
While there are many foods that are safe when you're not pregnant but unsafe when you are, protein bars -- at least generally speaking -- aren't among them and should be okay to eat when pregnant. During pregnancy, you need protein -- just as you do when you're not pregnant -- to serve several purposes.
While you don't need more of most vitamins and minerals during pregnancy than you do when you're not pregnant, you do need more iron and folic acid, which some protein bars contain. You can look for these in the ingredients or on the nutrition facts label.
