Final answer:
Vegetarian pregnant women typically have adequate intake of Vitamin C but may need to monitor and increase their intake of Iron, Vitamin B12, and Folate to ensure a healthy pregnancy.
Step-by-step explanation:
Pregnant women who are vegetarians are at risk for consuming inadequate amounts of many important nutrients, but one nutrient they typically consume enough of is Vitamin C (Ascorbic Acid). While vegetarian diets might have limitations concerning Iron (Fe), Vitamin B12 (B12), and Folate (Folic Acid), which are crucial during pregnancy for various health reasons including the prevention of neural tube defects and anemia, they usually provide sufficient Vitamin C. This vitamin is abundant in a plant-based diet, particularly in fruits and vegetables. To ensure that they meet their nutritional needs, pregnant vegetarians should be mindful of their intake of Iron, Vitamin B12, and especially Folate, with the latter being highly regarded for its role in reducing the risk of neurological birth defects like spina bifida.
