If you follow a plant-based diet, you’re probably aware of concerns about whether you’re consuming enough protein. But there are plenty of vegan sources of protein that you can incorporate into your diet, many of which you might be eating already.

This isn’t to say that eating adequate amounts of protein as a vegan is something you can do without thinking – hitting your daily protein requirements might require more thought than it does for people who eat meat and fish. How much protein you need will depend on a number of factors too, including how much you exercise – people who are more active have higher requirements for protein and may need to supplement with the best protein powder for women.

The reason many people believe it can be difficult to obtain enough protein when eating a largely plant-based diet is because most vegetarian sources of protein, with the exception of soy and quinoa, are considered incomplete. 

“This means that they do not provide all the essential amino acids (EAAs),” says Farah Z Khan, a registered dietician. “Proteins are comprised of amino acids, nine of which are essential – meaning they must be obtained from the diet.”

She adds: “Animal proteins provide adequate amounts of all EEAs, whereas plant proteins lack one or more. So, an individual who is vegan must ensure that they are consuming a variety and an adequate amount of plant protein sources to obtain adequate amounts of all the EAAs.”

The other big reason why you might need to think carefully about the amount of protein you’re consuming on a vegan diet is that plant proteins have a lower PDCAAS score (protein digestibility and corrected amino acid score) than animal proteins. This means that the amino acids in these sources are not as well absorbed and assimilated into the body as animal proteins. 

“For this reason, an individual who is vegan would have to consume a larger amount of plant proteins (compared with animal proteins) to absorb and assimilate an equivalent amount,” says Khan.

However, there are benefits of eating plant proteins like legumes. “They provide fiber and many vitamins and minerals,” says Khan. “Fiber is important for gut health, and it is also a nutrient we do not get from animal proteins.”

Here are seven vegan sources of protein you can start incorporating into your diet.

Vegan sources of protein

1. Soy (tofu, tempeh, soy milk)

“Soy is considered a complete protein in that it provides all the EAAs,” Khan says, adding that: “Fortified soy can also provide calcium, vitamin D and vitamin B12.”

Soy is a versatile ingredient as you can add soy milk to your cereal or morning coffee, make stir fries and curries with tofu and tempeh or even use soy milk and cream when baking.

2. Lentils

Lentils are a great source of vegan protein and they tend to be a little easier to digest compared with beans. Plus, they provide a wide range of nutrients: “In addition to protein, they provide iron, phosphorus, potassium, folate and magnesium,” says Khan.

There are many types of lentils (French, black, yellow, orange) and you can make a range of dishes, such as curries and soups using them. Lentils are an incomplete protein but pairing them with a grain (such as rice or whole grain bread), can help you obtain a complete set of EAAs.

3. Beans and chickpeas

Beans and chickpeas are part of the legume family (along with lentils), and provide similar nutritional benefits. “Beans and chickpeas are great sources of fiber, plus they provide iron, folate and other B vitamins, potassium, phosphorus and magnesium,” says Khan. She adds: “The fiber in beans, chickpeas and lentils is not only great for our gut health, but it also slows digestion, and helps to stabilize the rise in blood sugar after a meal.”

Beans and chickpeas are great for stews and chillies and they can also be added to salads for extra protein.

4. Pseudo grains, such as quinoa

“Quinoa is often considered a grain, but it’s technically a seed,” Khan says. “Like soy, quinoa is considered a complete protein (provides all the EAAs) though one would have to eat a considerable amount of quinoa to obtain a sizable amount of protein.”

Quinoa works well in salads and it can also be used as an alternative to rice as a side or base for a meal.

5. Seitan (wheat gluten)

Seitan is a popular “mock meat” that resembles the texture of meat. Plus, it’s a great source of protein. “Nutrients in seitan include iron, calcium, phosphorus and selenium,” says Khan. Although she stresses that you should avoid seitan if you have celiac disease or a gluten sensitivity. Seitan can be used in place of meat as a replacement in almost any meal, from stir fries to curries and even burgers.

6. Hemp seeds

You may not think that seeds are a good source of protein but hemp seeds are a good choice for vegans who are looking to increase their protein intake. They’re also a great source of healthy fats, such as omega 3 and they contain magnesium, zinc, iron and selenium. You can sprinkle hemp seeds over smoothie bowls, cereal or on top of savory meals like salads.

7. Nutritional yeast

Nutritional yeast is commonly used as an alternative to cheese for people who follow a plant-based diet and it’s also a good source of protein, which is a bonus. “As well as protein, it provides significant amounts of other vitamins including B1, B2 and B3, folate and B12,” says Khan.

Nutritional yeast is also versatile in that it can be used as a seasoning for many dishes and you can also use it to create creamy sauces for pasta dishes and curries.
