Vegan Protein Sources: A Comprehensive Guide

It's a common misconception that vegan diets lack sufficient protein. However, there are plenty of plant-based sources of protein, including legumes, grains, nuts, seeds, and soy products.

The average person needs approximately 0.45–0.73 grams of protein per pound of body weight daily, depending on their physical activity level. For a vegan diet to be healthy, it's important to include a variety of protein sources, as certain plant foods contain significantly more protein than others.

Some examples of vegan protein sources include:

- Seitan

- Tofu

- Tempeh

- Edamame

- Beans

- Lentils

- Quinoa

- Oats

- Chia seeds

- Hemp seeds

- Spirulina

- Nutritional yeast

- Nuts

- Green peas

Legumes, including beans, peas, and lentils

Nutritional Value

Legumes are an excellent source of plant-based protein. Beans, for example, are extremely important staple foods across cultures and contain high amounts of protein per serving. Most types of beans provide about 15 grams of protein per cooked cup (170 grams). This includes kidney beans, black beans, pinto beans, and chickpeas.

Lentils are another exceptional protein source, offering 18 grams of protein per cooked cup (200 grams). They also provide over half of the recommended daily fibre intake in a single cup and promote a healthy gut by feeding good bacteria in the colon.

Peas, such as green peas, also contribute a good amount of protein to a vegan diet, with nearly 9 grams of protein per cooked cup (160 grams).

Health Benefits

Legumes are not only protein-rich but also offer a range of other health benefits. They are excellent sources of complex carbohydrates, fibre, iron, folate, phosphorus, potassium, manganese, and various beneficial plant compounds.

Research suggests that including legumes in your diet can help decrease cholesterol levels, manage blood sugar, lower blood pressure, and reduce belly fat. Lentils, in particular, may also lower the risk of heart disease, diabetes, excess body weight, and certain types of cancer.

Incorporating Legumes in a Vegan Diet

Legumes are versatile and can be incorporated into a vegan diet in numerous ways. You can enjoy them as a simple side dish or get creative and include them in burritos, soups, salads, curries, hummus, and even desserts like chia seed pudding.

For example, you can use lentils as a taco filling, in chilli, or as a curry base. Beans are incredibly versatile and can be blended into hummus, formed into fritters, or used as baked potato toppers. Chickpeas, also known as garbanzo beans, work well in curries and hummus, providing about 15 grams of protein per cooked cup.

Peas can be added to curries, roasted as a crispy side dish, or blended into smoothies. You can also enjoy them as a snack, either steamed or boiled, like edamame beans.

Comparison with Other Protein Sources

Legumes are comparable to other plant-based protein sources and often offer higher protein content. For example, tempeh, a soy product, provides about 13 grams of protein per 3/4 cup (100 grams), while tofu offers 4 grams of protein per 3 ounces (85 grams). Seitan, a wheat gluten product, provides 19 grams of protein per 3 ounces (100 grams).

In summary, legumes, including beans, peas, and lentils, are an excellent source of protein in a vegan diet. They are versatile, nutritious, and offer various health benefits. By incorporating them into your meals in creative ways, you can ensure you meet your daily protein requirements while enjoying delicious and healthy plant-based meals.

Soy products, such as tofu, tempeh, and edamame

Soy products such as tofu, tempeh, and edamame are excellent sources of plant-based protein. All three are made from soybeans, which are considered a whole source of protein, providing the body with all the essential amino acids it needs.

Tofu is made from condensed soy milk that is pressed into white blocks. It comes in a variety of textures and takes on the flavour of the foods it is cooked with. A 3-ounce (85-gram) serving of tofu provides approximately 8 grams of protein, as well as 12% of the Daily Value (DV) for calcium and smaller amounts of potassium and iron.

Tempeh, on the other hand, is made from fermented soybeans, often combined with other seeds and grains, forming a firm, dense cake. It has a chewier and nuttier flavour than tofu. Three ounces (85 grams) of tempeh contain 11 grams of protein, along with a good source of fibre, iron, potassium, and calcium.

Edamame beans are green, whole, immature soybeans with a slightly sweet and grassy flavour. They are usually steamed or boiled and can be enjoyed as a snack or added to salads, soups, or grain bowls. A 1/2 cup (85 grams) of whole edamame provides 8 grams of protein, as well as a good amount of fibre, calcium, iron, and vitamin C.

In addition to being a good source of protein, soy products such as tofu, tempeh, and edamame also offer various other nutritional benefits. They are a good source of iron, calcium, and B vitamins, and can help support digestion and regularity. Tempeh also contains probiotics and minerals such as magnesium and phosphorus.

Nuts and seeds, including hemp seeds, almonds, and chia seeds

Nuts and seeds are a great source of protein for vegans, offering a range of health benefits. Hemp seeds, almonds, and chia seeds are all protein-rich foods that can be easily incorporated into a vegan diet.

Hemp seeds are a complete protein, containing all nine essential amino acids. They are also a good source of magnesium, iron, calcium, zinc, and selenium. With 9 grams of protein in a 3-tablespoon (30-gram) serving, hemp seeds are a convenient way to boost your protein intake. They have a mild nutty flavor and can be sprinkled over yogurt or salads, added to smoothies, or included in homemade granola and energy bars.

Almonds are another excellent source of protein for vegans. With 20.33 grams of protein per 100 grams, almonds are a nutrient-dense snack. They are also a good source of fiber, healthy fats, calcium, magnesium, selenium, phosphorus, vitamin E, and B vitamins. Almonds are versatile and can be eaten on their own or added to recipes, such as vegan cream cheese or parmesan.

Chia seeds are tiny black or white seeds that are also a complete protein. They are extremely versatile and can be used as an egg substitute in vegan baking, sprinkled on yogurt or salads, or added to baked goods and smoothies. With 18.29 grams of protein per 100 grams, chia seeds are a great way to boost your protein intake while also getting a good source of omega-3s, iron, calcium, magnesium, and selenium.

When it comes to meeting protein requirements on a vegan diet, it's important to include a variety of plant-based protein sources. Nuts and seeds, including hemp seeds, almonds, and chia seeds, offer not only protein but also a range of other essential nutrients, making them a valuable addition to a balanced vegan diet.

Grains, including quinoa, oats, and wild rice

Grains are an excellent source of protein in a vegan diet. Quinoa, oats, and wild rice are not only tasty and nutritious but also provide a good amount of protein.

Quinoa is often marketed as a "superfood" due to its high nutrient content. It is a seed that is prepared and consumed like a cereal grain but is technically a pseudocereal. Quinoa has a crunchy texture and a nutty flavour. It is gluten-free, making it suitable for people with gluten intolerance. A cup of cooked quinoa (around 185 grams) contains 14.6% protein, which is higher than most cereal grains. It is considered a complete protein source, providing all nine essential amino acids. Quinoa is also a good source of antioxidants, vitamins, and minerals such as manganese, phosphorus, copper, folate, iron, magnesium, and zinc.

Oats are a whole-grain cereal that is commonly consumed as oatmeal (porridge) or used in baked goods, bread, muesli, and granola. They are a good source of vitamins, minerals, and unique plant compounds. Oats offer quality protein, with 11-17% of dry weight, which is higher than most other grains. The major protein in oats, avenalin, is not found in any other grain. Oats also contain the minor protein avenin, which is related to wheat gluten. However, pure oats are generally safe for people with gluten intolerance. Additionally, oats are a good source of beta glucan, a type of soluble fiber that provides numerous health benefits, including lowering cholesterol and improving heart health.

Wild rice, despite its name, is not rice but rather the seed of an aquatic grass. It has a stronger flavour and is usually more expensive than regular rice. Wild rice is a good plant-based protein source, containing twice as much protein as brown or white rice. A 3.5-ounce serving of wild rice provides 4 grams of protein. It is considered a complete protein, containing all nine essential amino acids. Wild rice is also a good source of several nutrients, including magnesium, phosphorus, copper, manganese, and zinc. Additionally, it is high in antioxidants, which may help reduce the risk of certain diseases.

Incorporating grains like quinoa, oats, and wild rice into a vegan diet is a delicious and nutritious way to increase your protein intake while also benefiting from the various vitamins, minerals, and antioxidants they provide.

Broccoli

Broccoli is a very popular vegetable that contains protein with all the essential amino acids. One cup (88g) of chopped broccoli contains 2.5g of protein. Broccoli is also a very rich source of vitamins C and K, and a good source of folate, phosphorus, and potassium. It also contains some calcium. Broccoli can be steamed, roasted, baked, or sautéed, and it works well in soups and sauces or as a side dish.

Spinach

Spinach is one of the most nutrient-dense leafy green vegetables a person can eat. One cup (25g) of raw spinach contains 0.7g of protein. The protein in spinach contains all essential amino acids. Spinach is also a rich source of folate, vitamin A, and vitamin C; a good source of magnesium and potassium; and a decent source of calcium. Spinach contains plant compounds that can increase antioxidant defence and reduce inflammation. Spinach can be added to salads or smoothies, blended into soups, or added to curries and stews.

Sweet Potatoes

Sweet potatoes are a good source of protein in many developing countries. A medium-sized sweet potato holds 2g of protein. Sweet potatoes are mainly composed of carbs, most of which come from starch, followed by fiber. Sweet potatoes are also an excellent source of beta carotene, vitamin C, and potassium. They are also a decent source of many other vitamins and minerals. Sweet potatoes can be boiled, baked, steamed, or fried.
