If you follow a vegan diet and are pregnant or planning for pregnancy, it’s important to supplement your diet during this time. This helps make sure you and your baby receive all the nutrients needed for optimal health. Pregnant women on a vegan diet may experience a lower risk of excessive weight gain and gestational diabetes. They may also face fewer cases of preeclampsia and reduced maternal postpartum depression. However, vegan pregnancy may be at risk of certain nutrient deficiencies. Understanding which vegan foods to include in your diet can contribute to a healthy pregnancy journey.
Is a Vegan Diet Safe During Pregnancy?
Vegan diets during pregnancy have historically faced criticism due to concerns about potential nutrient deficiencies, especially in vitamin B12, iron, calcium, and omega-3 and 6 fatty acids. These nutrients are important for foetal development and maternal health.After extensive research, it has been found that a vegan diet during pregnancy can be safe, if carefully planned to meet nutritional needs. Adequate intake of protein, iron, calcium, vitamin B12, vitamin D, omega-3 fatty acids, and folate is crucial for your health and the developing foetus.
These nutrients can be sourced from plant-based foods. Well-planned vegan diets can support healthy pregnancies without increasing the risk of complications compared to omnivorous diets. However, deficiencies in B12 or iron, common in poorly planned vegan diets, can lead to anaemia or developmental problems. Consulting a dietitian helps maintain the right nutrient balance, particularly for first-time vegan moms.
Benefits of a Vegan Diet During Pregnancy
Below are some key benefits of following a vegan diet during pregnancy:- Lower risk of preeclampsia: Preeclampsia is a serious pregnancy-related condition marked by high blood pressure and potential liver or kidney damage. A vegan diet rich in fruits, vegetables, and whole grains may reduce the risk of preeclampsia. This is due to its high content of antioxidants, fibre, and anti-inflammatory compounds. Plant-based diets can help maintain healthy blood pressure levels during pregnancy.
- Lower risk of gestational diabetes: Vegan diets are generally lower in saturated fats and higher in fibre. This may help reduce the risk of gestational diabetes by improving insulin sensitivity. If you have gestational diabetes, following a vegan diet may also lower the possibility of needing a C-section.
- Lower risk of certain neural tube defects: A high intake of folate from vegan sources such as leafy greens, legumes, and fortified grains can reduce the risk of neural tube defects.
Risks of a Vegan Diet During Pregnancy
Some of the key nutrients to be mindful of when following a vegan diet during pregnancy are:- Vitamin B12: A lack of vitamin B12 can increase the risk of miscarriage, gestational diabetes, preterm birth, and birth defects. This nutrient is important for neurological development. As it is primarily found in animal products, vegans must turn to supplements to meet their B12 needs.
- Vitamin D: Insufficient vitamin D can increase the risk of preeclampsia, low birth weight, and miscarriage. It helps in calcium absorption and proper immune function during pregnancy.
- Iron: Your body doesn’t absorb non-heme iron from plant foods as efficiently as heme iron from animal products. Inadequate iron intake can lead to anaemia, increasing the risk of preterm delivery or low birth weight.
- Iodine: Low iodine levels can affect thyroid function and may lead to developmental delays in the foetus. Vegan diets often lack iodine unless seaweed, iodised salt, or supplements are added.
- Calcium: Low calcium intake can negatively affect maternal health, increasing the risk of preeclampsia, fractures, and bone disease.
- Omega-3 fats: Insufficient omega-3 fatty acids, particularly eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), can impact the development of the foetus's brain and eyes.
- Protein: Insufficient protein can affect the growth of the foetus and the development of maternal tissue.
- Zinc: Low zinc levels may contribute to prolonged labour, preterm birth, or impaired immune function, as zinc supports cell division and immunity.
- Choline: Inadequate choline intake can impact foetal brain development and increase the risk of neural tube defects.
What to Include in a Vegan Diet During Pregnancy?
Eating the right foods is important for a healthy vegan pregnancy. Since some nutrients are harder to get from plant-based sources, your diet needs extra care. Here’s what to include in your vegan diet during pregnancy:- Tofu is rich in calcium, protein, iron, and magnesium. It serves as an alternative to meat and dairy, however, it is a soy derivative and must be consumed in moderation.
- Lentils, chickpeas, black beans, and peas are loaded with fibre, protein, and folate. Sprouting, fermenting, or thoroughly cooking them improves nutrient absorption.
- Most nuts and seeds, like almonds, pumpkin seeds, and sesame seeds, are great sources of calcium, zinc, and healthy fats.
- Fortified almond, soy, or oat milks and yogurts provide substantial calcium and vitamin D. Choose unsweetened options to maintain a balanced diet.
- Nutritional yeast is often fortified with vitamin B12 and adds a savoury, cheese-like flavor. It’s also a good source of protein.
- Whole grains and cereals are rich in iron, magnesium, and antioxidants.
- Sprouted grains or legumes enhance nutrient bioavailability, providing protein, iron, and small amounts of calcium.
- Berries, oranges, carrots, and leafy greens such as kale and spinach are rich in folate, vitamin C, and antioxidants.
Foods to Avoid During a Vegan Pregnancy
It's important to know what foods to avoid to keep you and your baby safe:- Highly processed vegan junk foods are high in added sugars, unhealthy fats, and sodium. Overconsumption may lead to excessive weight gain or nutrient imbalances.
- Raw or undercooked sprouts can carry harmful bacteria like Salmonella. These pose risks of food poisoning.
- High-sodium mock meats are loaded with salt and preservatives. Excessive intake can contribute to high blood pressure.
- Caffeinated and sugary beverages like energy drinks, sodas, and excessive coffee contain high caffeine or sugar levels.
- Raw or undercooked beans, lentils, or grains may contain anti-nutrients like lectins or be hard to digest.
- Alcohol should be completely avoided during pregnancy. There is no known safe amount of alcohol during pregnancy, so it's best to cut it out entirely.
