Is it safe to eat a vegan pregnancy diet?
As veganism becomes more popular, many women are choosing to follow a plant-based diet — even during pregnancy.
While a vegan diet — which excludes all animal products — can offer certain health benefits, it also carries a higher risk of nutritional deficiencies if not carefully managed. Because pregnancy places increased demands on your body, a vegan pregnancy diet is generally not considered safe without close medical and nutritional supervision.
In contrast, a balanced vegetarian pregnancy diet that includes eggs and dairy (but excludes meat and fish) is widely recognized as safe and nutritionally adequate for a healthy pregnancy.
Vegan diet while pregnant
In general, plant-based diets are healthy, but during pregnancy they may pose risks because certain nutrients—needed in higher amounts during pregnancy—are found mainly in animal sources.
A vegan diet while pregnant excludes all foods of animal origin, i.e. not only meat and fish, but also milk, dairy products, eggs, gelatin, honey, etc.
Vegan and pregnant – a good idea?
Expectant vegans should prioritize careful nutritional planning to support a healthy pregnancy. While a well-planned vegan diet can theoretically provide all the essential nutrients, extra attention — and in some cases supplementation — is needed for protein, calcium, iron, omega-3 fatty acids, and vitamin D.
Nutritional guidance is crucial to prevent deficiencies that could affect fetal development. Being vegan and pregnant can be challenging and requires extra care and nutrition knowledge to ensure you’re getting the right amount of key vitamins and minerals.
Vegan diet pregnancy – what you need to know
A vegan pregnancy diet has historically raised concerns because it may not provide enough of certain essential nutrients. Micronutrients such as vitamin B12, vitamin D, omega-3 fats, iron, iodine, calcium, and zinc are especially important during pregnancy, and their levels in plant-based diets can be too low or less readily absorbed by the body.
For this reason, the topic of vegan diet pregnancy is often discussed in relation to careful planning and supplementation.
Vegan pregnancy and potential health challenges
A low intake of these nutrients can result in nutrient deficiencies and pregnancy complications. For instance, insufficient vitamin B12 levels during pregnancy may raise your risk of miscarriage, preterm birth, or birth defects.
In addition, a vegan pregnancy has been associated with lower birth weight, which may be linked to reduced maternal weight gain during pregnancy.
Vegan pregnancy and nutritional considerations
If you’re vegan, it’s important to ensure you’re getting enough iron and vitamin B12, which are commonly found in animal products, as well as vitamin D (often found in eggs), calcium (typically found in dairy), and iodine (in seafood).
A vegan pregnancy—without meat, fish, dairy products, and eggs—is therefore not ideal for pregnant women unless carefully planned.
If you want to eat a vegan pregnancy diet despite the indication of possible health risks for your baby, you may need personalized nutrition counseling, frequent medical check-ups (regular control of your blood values) and additional nutritional supplements.
Vegan while pregnant: Why supplements are a must
A vegan diet for pregnant women must include the right supplements to avoid falling short on essential nutrients needed for a healthy pregnancy. Women who are vegan while pregnant need to pay extra attention to key vitamins and minerals.
Good sources of vitamin B12 for vegetarians include milk, cheese, and eggs. For those who are vegan while pregnant, some great options are breakfast cereals fortified with B12, unsweetened soy drinks fortified with B12, yeast extract (like Marmite), and nutritional yeast flakes fortified with B12.
In addition, high-quality nutritional supplements are a must (including folic acid, vitamin B12, vitamin D, iodine, zinc, and calcium) to help prevent nutrient deficiencies during pregnancy.
If you don’t eat fish, supplements with long-chain omega-3 fatty acids, such as DHA, are also advisable. On top of that, taking extra iron makes sense, as plant-based iron is absorbed less efficiently than iron from animal sources.
Vegetarian diet during pregnancy: A safe choice
On the other hand, a well-planned vegetarian diet during pregnancy (excluding meat, poultry, and fish but including protein sources like eggs and dairy products) can be considered safe and nutritionally adequate during pregnancy and lactation!
However, attention must be given to certain nutrients that are less abundant in plant-based sources. Pregnant women following a lacto-ovo-vegetarian diet should ensure adequate intake of vitamin B12 through dairy and eggs, and consider supplementation to be on the safe side when nutrition matters most.
Plant-based pregnancy diet
Vegetarians can continue to avoid meat and fish during pregnancy by following a healthy plant-based pregnancy diet. It’s just important to choose the right foods – such as pulses, tofu, eggs and dairy products for that extra portion of protein!
