You can follow a vegetarian diet throughout your pregnancy, and with careful planning, you can get all the nutrients you and your baby need.
Make sure to follow a healthy eating plan and keep your protein levels up by eating foods like soy products, dried beans, and peanut butter. You also want to make sure you are getting enough iron from non-meat sources. Make sure to include vitamin C-rich foods to increase iron absorption. Be sure to take a prenatal supplement as prescribed by your doctor.
