Being pregnant does not mean you have to give up your vegetarian lifestyle. However, just as with any other eating style, if you are following a vegetarian diet during pregnancy, you must ensure that you get well-balanced and varied meals. Although the typical vegetarian diet is very low in saturated fat and cholesterol, not all diets are low in calories, total fat, or sugar. Some can also be lacking in other essential vitamins and minerals unless they are properly planned.
