Maternal nutrition during pregnancy plays an important role in the health of the mother and optimal foetal development. A well-balanced vegetarian or vegan diet can assist in maintaining optimal blood pressure and preventing excessive weight gain, reducing the likelihood of complications during pregnancy. Including a vegetarian or vegan diet during pregnancy requires careful planning to ensure essential nutrients for both the mother and baby. Even though these plant-based lifestyles can offer numerous health benefits, it is crucial for expectant mothers to carefully plan their diets, ensuring a sufficient intake of essential nutrients such as Vitamin B12, iron, and omega-3 fatty acids through supplements or fortified foods to support overall maternal and foetal well-being.
Essential Nutrients to Include
Iron: Iron is essential for your baby’s growth and development. A deficiency of iron can also cause you to feel tired. Anaemia caused by an iron deficiency can occur during pregnancy and can be diagnosed by a blood test. Eating plant-based foods makes it easier to absorb iron than animal products. Vegetarians and vegans should include high-quality iron-fortified foods in their diet, including beans, peas, lentils, green leafy vegetables, seed and wheat germ bread, quinoa, dried apricots and figs, sesame and pumpkin seeds.
Vitamin B12: Vitamin B12 is essential for your baby’s growth and development and helps the body to absorb energy from food. Vitamin B12 is naturally found in meat, dairy, and eggs. However, vegans don’t get as much vitamin B12 because there aren’t as many reliable sources. If you’re a vegetarian who eats eggs and dairy products regularly, you have to make sure you’re getting enough B12. The only reliable source of B12 for vegans is fortified foods.
Calcium and vitamin D: Calcium is essential for the development of your baby’s bones, and it also helps to keep your bones healthy. Dairy foods such as milk and yoghurt are good sources of calcium. If you can, try to choose lower-fat and lower-sugar versions, as they are likely to have at least as much calcium as the higher-calorie options. Cheese is another great source of calcium. If you’re vegan, you need to eat more foods that are fortified with calcium, such as bread made with non-whole wheat flour, green leafy vegetables, fortified plant milk, tofu, etc. that are essential for the development of the baby’s bones. For vitamin D synthesis, safe sunlight exposure or supplementation may be essential, especially in vegan diets with limited natural sources.
Protein: Protein is composed of amino acids that are essential for the building of your body’s cells – and your baby’s. The body cannot make these amino acids on its own, so they need to be sourced from your diet. Most vegans and vegetarians eat enough protein to meet their needs, but it is important to eat a variety of proteins to ensure you are getting all the essential amino acids you need. One of the best sources of protein for vegetarians and vegans is soybeans. Other sources include dairy products like milk, yoghurt, and cheese, some dairy alternatives like soy drinks, beans and other pulses (kidney soya, and lentils), nut butter (nuts, almonds, and cashews) and other protein-based products.
Omega-3 fatty acids: Omega-3 fatty acids are crucial for foetal brain development, they are commonly sourced from fish in traditional diets. Vegans can obtain these fatty acids from sources such as flaxseeds, chia seeds, vegetable oils (rapeseed and soybean oil), and walnuts.
Benefits of Vegetarian and Vegan Diet during Pregnancy
Nutrient-rich choices: A vegetarian or vegan diet during pregnancy can provide ample essential nutrients such as folate, vitamins, and minerals essential for foetal development. Plant-based options such as leafy greens, legumes, and fortified foods contribute to a well-rounded nutritional profile.
Lower risk of gestational complications: Studies suggest that a vegetarian or vegan diet may be associated with a lower risk of gestational complications such as gestational diabetes and preeclampsia. The high fibre and lower saturated fat content in plant-based diets may contribute to these benefits.
Healthy weight management: Vegetarian and vegan diets often support healthy weight management during pregnancy. Emphasizing whole foods and minimizing processed options can assist in maintaining optimal weight, and reducing the risk of complications.
Digestive health and comfort: The fibre-rich nature of plant-based diets can aid in maintaining healthy digestion and preventing common pregnancy-related discomforts such as constipation. A well-balanced vegetarian or vegan diet includes diverse fibre sources.
Environmental and ethical considerations: Opting for a vegetarian or vegan lifestyle aligns with environmental sustainability and ethical choices. Knowing that dietary choices support both personal health and well-being of the planet can enhance the overall pregnancy experience.

To summarize, adopting both vegetarian and vegan diets can be safe and healthy during pregnancy with proper planning and nutritional awareness. Understanding the potential challenges and ensuring adequate intake of essential nutrients, such as iron, calcium, protein, and key vitamins, is essential for the health of both the mother and the developing foetus. A carefully planned diet that addresses potential deficiencies can contribute to a successful and healthy pregnancy, regardless of the chosen dietary path.
