Plant-Based Protein For Pregnancy

Plant-Based Protein For Pregnancy

Eating plenty of protein before and during pregnancy is essential for a variety of reasons! Research states that a protein-rich diet is linked to increased fertility and embryonic survival, as well as the healthy growth and development of the fetus. Protein is also a key to feeling full and satisfied after meals and keeping up a healthy weight gain during pregnancy. A steady influx of protein will also help you maintain strong muscles as your body goes through the many changes associated with pregnancy. 

Protein needs will vary per individual, but research shows adverse outcomes with both under-consuming and over-consuming it. You will learn how to calculate your unique protein needs inside The Prenatal Nutrition Library

Studies show that under-consuming protein during pregnancy may lead to serious complications. These could include embryonic loss, intrauterine growth restriction, and reduced postnatal growth. 

The most common food group people think of when talking about protein is meat. Luckily, you can get protein from many different sources though. It’s actually wise to choose a variety of both plant and animal proteins because these foods also contain many other nutrients in addition to protein. Also, if you’re feeling averse to meat in the first trimester, plant-based options can be a great option to turn to!

The foods we are discussing today are all plant-based sources of protein as well as other vitamins, minerals, fiber, and healthy fat. As mentioned above, you’ll see that these foods contain a multitude of other essential vitamins and minerals required for a healthy pregnancy. 

So, let’s dive right in and discuss some good sources of plant-based protein that are safe to eat during pregnancy! 

Plant-Based Protein For Pregnancy

Plant-Based Protein Sources For Pregnancy


Tofu originates from soybeans and is a very rich source of plant-based protein. It’s common to use tofu as a substitute for meat on salads, in stir-fries, and even with pasta. You can also add silken tofu to smoothies for an extra kick of protein. In addition to protein, tofu is also a rich source of vitamins and minerals, including iron and calcium.

Seitan is made from vital wheat gluten and, like tofu, it is a good source of plant-based protein. This plant-based source of protein contains all nine essential amino acids. However, it is lower in lysine so be sure to include a variety of protein sources in your diet. To give your next healthy lunch idea for pregnancy a bigger boost of protein, include some pan-fried or grilled seitan!

Tempeh has a naturally nutty flavor and, like tofu and seitan, is very popular among vegetarians and vegans as a source of plant-based protein. It is traditionally made from fermented soybeans. This nutrient-dense food contains protein as well as magnesium, calcium, iron, and more. It tastes delicious in stir-fries or fajitas!

Hemp seeds

Hemp seeds are one of my favorite seeds for pregnancy. And if you’re wondering, yes, they are a safe seed option for pregnancy. Hemp seeds are so versatile and can be thrown into smoothies, oatmeal, yogurt, or even used as a topping on toast. They are also a good source of healthy fats, fiber, and plant-based (non-heme) iron.

Chia seeds

If superfoods were a real thing, chia seeds would be one! They make a great addition to a healthy breakfast during pregnancy, including stirred into overnight oats, yogurt, smoothies, or even made up into a delicious chia seed pudding. Besides adding a few grams of protein to your diet, chia seeds are also a good source of non-dairy calcium, fiber, magnesium, non-heme iron, antioxidants, and healthy fats!

Higher protein vegetables 

Now, while vegetables aren’t going to be your richest source of protein, some veggies pack in a few more grams of protein than others and can boost your overall diet. Of course, vegetables are also rich in other nutrients that are good for mom and baby too. Green peas, brussels sprouts, asparagus, and broccoli are among some of the higher protein vegetable choices.

Black beans

Like many other beans, black beans are a good source of plant-based protein. Black beans make a good topping in tacos, bowl meals, quesadillas, or salads. In addition to protein, black beans are also a good source of fiber and folate – a very important nutrient for pregnancy.

Cooked soybeans are a very rich source of plant-based protein. Soybeans are commonly found in hummus recipes and used to make other products such as soy milk, tofu, and tempeh. In addition to protein, soybeans are also a source of fiber, folate, copper, phosphorus, and molybdenum.

Another legume well-known for its protein and nutrient boost is chickpeas. Chickpeas, also known as garbanzo beans, are another common ingredient in hummus or side dishes. In addition to protein, chickpeas are a good source of fiber, iron, potassium, and magnesium.

Kidney beans

Kidney beans come in a variety of shapes, colors, and patterns. Chili, bean-based burgers, and bean salads are a few great ways to add kidney beans to your diet. Kidney beans are packed with fiber, protein, folate, potassium, and vitamin K1. 

For the best taste, you can season kidney beans with natural herbs and spices in addition to a pinch of sea salt and pepper.

Lentils, while they look more like seeds, are in the legume family because they grow in pods. There are a variety of types of lentils and they are super healthy and nutritionally dense food. They are packed with a plethora of essential vitamins and nutrients that are important for both mom and baby’s health, growth, and development. In addition to protein, lentils contain fiber, thiamine, niacin, folate, zinc, iron, and more!

Both nuts and seeds provide an awesome boost of protein as well as healthy fats and other essential vitamins and minerals. They also make a super healthy snack idea during pregnancy! Peanuts, cashews, walnuts, and almonds are a few great options that could be added to your pregnancy diet.

Peanut butter

Yum…. who doesn’t love a good spoonful of peanut butter? Peanut butter is an excellent source of protein, vitamin B6, fiber, and magnesium. It makes a tasty addition to smoothies, toast, oatmeal, and yogurt. I recommend opting for an option without added sugar or vegetable oils.

Other nut butters

Not a peanut butter fan? No problem! Like peanut butter, other nut butters can provide a good boost of protein and other nutrients. For example, almond, cashew, walnut, pecan butter, and more! And, just one spoonful of nut butter can help manage those pesky sugar cravings commonly experienced during pregnancy too.

Plant-based protein powder

Protein powder can be used in a variety of ways to provide a great boost of protein. Many pregnant people find it especially helpful in the first trimester when feeling nauseous. While protein powder contains a good boost of protein, it shouldn’t be your sole source of this essential nutrient. For an extra protein boost, throw one scoop of pregnancy-safe protein powder into a smoothie or liquid of your choice and drink up! Need some smoothie inspiration?
