Another important nutrient that you need to think about when you decide to start a vegetarian diet is calcium. Vegetarians who are not giving up dairy products will still be able to get good amounts of calcium from these food items and milk and eggs both provide good sources of calcium. However, if you are not going to eat any animal products at all, there are food sources that are not animal-based that contain this nutrient.
For example, soy milk that is calcium-fortified, tofu that is made with calcium sulfate, orange juice, and breakfast cereals that have been fortified with calcium are all good ways to ensure that you are getting enough calcium in your diet. Dark green and leafy vegetables such as collard greens, mustard greens, spinach, and kale, are also great sources of calcium as well as other nutrients that your body is going to need.
