Pregnancy is an ideal time to pause and reassess your approach to your own health. Every positive change you make for yourself will be reflected in the health of your baby. It's important to choose a varied balanced diet during pregnancy. If you have special nutritional needs (e.g. veganism or food allergies/ intolerances) your diet may lack certain substances needed by yourself and your baby. For that reason you should talk to a dietitian. In addition all pregnant mothers in New Zealand need to take supplementary folic acid to prevent serious birth defects, such as spina bifida; and iodine for healthy brain development.
