Best Protein Sources for Vegans and Vegetarians

Protein is more than just a trendy buzzword in health and fitness. It's a vital nutrient that your body needs to build and repair tissue, produce hormones, and promote wellness. But getting enough protein in your diet can be complicated, especially if you’re a vegan or vegetarian.

The good news is many plant-based protein sources are nutritious and delicious. Let's dive into the world of vegan and vegetarianism and discover how to include protein in their diet.

The Challenge of Vegan and Vegetarian Diets

Meeting protein needs can challenge vegans and vegetarians, particularly those aiming to gain weight or build muscle. But, it's entirely possible to meet your protein requirements through plant-based sources with proper planning. For instance, nuts and seeds are excellent protein sources.

Other sources with high-protein content include:

  • Chia seeds
  • Wild rice
  • Oats and oatmeal
  • Quinoa
  • Tofu
  • Buckwheat

These plant-based foods, and many others, are not only rich in protein but also packed with other vital nutrients. Broccoli, Brussels sprouts, and Asparagus have protein, even though you might not think of them as good sources.

Pitfalls of Vegans and Vegetarians

Nevertheless, a common pitfall of vegan and vegetarian diets is the potential risk of protein deficiency. If you don't eat well, you may not get all the critical amino acids your body needs to make protein. This can lead to symptoms like fatigue, excessive hunger, and poor immunity.

The key to overcoming this is dietary diversity. Eating various plant-based protein sources will support a complete profile of essential amino acids. Protein deficiency is a concern when following a plant-based diet. Still, with some planning and knowledge, it's more than possible to get all you need from vegetarian and vegan protein sources.

The Role of Protein and Amino Acids

You can't mention proteins without amino acids, as both play a crucial role in human nutrition. Amino acids, which combine to form proteins, are essential for our bodies to function correctly. These structures are necessary for muscle repair and immune responses.

The human body needs 20 amino acids to make proteins, but only nine are “essential,” and we can't make them ourselves. So, they must get them from our diet. The protein needs of adults vary based on factors such as age, gender, and activity level. 

On average, most adults need approximately 50 grams of protein per day. Both animal and plant-based sources can help you get enough protein. Animal proteins are "complete proteins" since they have all nine essential amino acids. 

However, many plant-based foods also have a good amount of protein. Soy products, quinoa, and buckwheat are all complete proteins. We can combine other plant foods, like beans and nuts, to get all the essential amino acids. 

So, no matter your dietary preferences, there are plenty of ways to get the protein your body needs.

Benefits of Plant-Based Proteins

Let's get one thing out of the way first: if you choose to, you can meet your protein needs with plant-based proteins. The world of nutrition has seen a significant shift towards plant-based diets, and for good reason. Research shows that plant-derived proteins can be as effective as animal-based proteins in meeting our dietary needs.

And if you're a health-conscious individual between 25-45 years old, there's even more reason to consider plant proteins. Many plant proteins have fiber, vitamins, minerals, and antioxidants and are cholesterol-free. Eating plant proteins can improve heart health, digestion, and overall well-being. 

Other health benefits of plant-based protein are:

  • Reduced Risk of Type 2 Diabetes
  • Lowered Cholesterol Levels
  • Weight Management and Appetite Control
  • Low or No Sodium
  • Little or No Saturated Fats

Beyond personal health, opting for plant proteins has broader benefits for our planet. Here are some key points to consider:

  • Lower Environmental Impact: Compared to animal agriculture, plant farming uses less water and land and emits fewer greenhouse gasses.
  • Sustainable Food Security: With rising global populations, plant-based proteins offer a more sustainable solution.
  • Animal Welfare: Choosing plant proteins helps reduce the demand for factory-farmed animals, promoting better treatment of livestock.

Remember, your protein intake isn't your only concern but also about the quality and diversity of your protein sources. Combining certain plant foods can provide all the necessary proteins, even with limited options.

Best Sources of Plant-Based Proteins

As we move forward, it's obvious that there are diverse protein-rich foods that can help you meet your nutritional needs. Generally, the types of plants that yield the most protein include legumes, grains, and certain seeds and nuts. These food groups offer a host of other health benefits by containing fiber, vitamins, and minerals.

Let's dive a little deeper into some specific high-protein vegan foods. First off, soybean foods like tofu and tempeh are excellent sources of protein and are incredibly versatile in cooking. Quinoa is another superstar and complete protein. Chia seeds and hemp seeds pack a protein punch.

Beans and legumes - everything from lentils to chickpeas offers a healthy dose of protein. You should include tasty nuts and nut butter (like peanuts, almonds, cashews, and their butter) too. 

Soybean Foods

Soy is a superfood, and for good reason. It's one of the few plant sources that offer complete proteins. This makes soy a nutritional powerhouse for vegans, vegetarians, and anyone looking to diversify their protein intake.

There are numerous soy food products that offer unique ways to include this versatile protein source into your diet:

  • Edamame: These young, green soybeans are delicious, boiled or steamed. You can eat them or add them to soups and salads.
  • Soy Milk: A common dairy alternative, soy milk works in everything from cereals and smoothies to baking recipes.
  • Soy Nuts: Roasted soy nuts make a crunchy, protein-packed snack or a great salad topping.

Mix and match these options to find your favorite ways to enjoy soy. Variety is important in your diet.


Quinoa, a staple in many vegan and vegetarian diets, is a nutritional powerhouse. This protein is unique as it contains all nine essential amino acids and is better than brown rice and barley. A cooked cup of this grain provides around 8 grams of protein.

It's also a good source of several components, including magnesium and fiber. Health-conscious people can include quinoa in their diet thanks to its versatility. You can use it as: 

  • A base for salads or stir-fries
  • A substitute for rice in grain-based dishes
  • An ingredient in baking

Its mild flavor allows it to blend well with various other ingredients. If you're feeling adventurous, why not try some creative quinoa recipes? Quinoa offers diversity, and vegans and vegetarians get protein, minerals, and fiber all in one. 

Chia Seeds and Hemp Seeds

Chia and hemp seeds are also complete protein sources, perfect for vegans and vegetarians. Chia seeds, tiny black or white seeds from the plant Salvia Hispanica, are protein-rich. They’re also chock full of fiber, omega-3 fatty acids, and various micronutrients. 

Hemp seeds come from the Cannabis Sativa plant and are an excellent source of protein, healthy fats, and vitamins. Adding these seeds to your diet is quite simple. Sprinkle chia seeds on top of salads, stir them into yogurt, or add them to baked goods for a nutritious boost. 

You can soak them in water or milk to make chia pudding, a popular breakfast item. In terms of hemp seeds, they possess a gentle, nutty taste that complements various culinary dishes. You can use them in your diet by adding them to smoothies, salads, or baked goods. 

Chia and hemp seeds are easy to find in stores and online, making them a convenient plant-based protein option.

Beans and Other Legumes

Legumes, which include beans, peas, lentils, and peanuts, are a staple in many vegan and vegetarian diets. These foods are high in fiber, vitamins, minerals, and protein, which is particularly important. Half a cup of legumes contains 115 calories, 1g of fat, 20g of carbs, 8g of protein, and 7-9g of fiber.

They have little fat and calories, so they're great for people who want to eat healthy. Legumes are a good protein source and contain lysine, an important amino acid for growth and bone health. Here are some common legumes that are excellent sources of protein:

  • Beans: Beans, especially black beans, have high protein content and can effectively substitute for meat. They also contain generous amounts of fiber and folate.
  • Peas: Peas are also tasty and provide ample fiber and potassium.
  • Lentils: Lentils are chock full of protein and are a versatile addition to soups, salads, and more.
  • Peanuts: Although technically a legume, peanuts have a similar nutrient profile to nuts. They are a good source of protein and also contain healthy fats.

Vegans and vegetarians should eat 3 to 4 servings of legumes daily to get enough protein and meet their nutritional needs.

Nuts and Nut Butter

Nuts are a fantastic source of essential nutrients, making them ideal for any diet, particularly vegans and vegetarians. Eating nuts provides healthy fats, fiber, vitamins, and minerals. Nuts have complex nutrient matrices rich in healthy fatty acids and other compounds.

Although they are high in fat, it's mainly healthier fats. However, despite the healthy fat, the calories are higher, so moderation is key. Here are some popular nuts and nut butter, along with their specific nutritional benefits:

  • Almonds: A serving of roughly 24 almonds provides around 165 calories, 6 grams of protein, and 14 grams of total fat.
  • Walnuts: They have high omega-3 fatty acid content, which promotes better heart health.
  • Cashews: Cashews are an excellent source of iron, magnesium, and zinc. These minerals provide support for the immune system and metabolism.
  • Cashew Butter: For people with allergies or a distaste for peanut butter, cashew butter is a fantastic substitute.
  • Almond Butter: It provides a good amount of protein and fiber, but check the label to avoid brands with added sugars.

Nuts have protein and nutrients, but they also have lots of calories and fat. Some nut butter can have a lot of sugar. It’s crucial to consume them in moderation as a part of a well-balanced diet.

More Protein Sources for Vegetarians

Vegans and vegetarians don't eat meat, but their diets vary in the amount of animal products on the menu. Vegetarians typically avoid meat but may consume dairy products, eggs, and honey, which a vegan diet excludes. As a result, vegetarian sources of protein are easier to find than they are for vegans.

Here are some additional vegetarian protein sources:

  • Eggs: A good source of protein and also rich in vitamin B2 and selenium, a standard inclusion in many vegetarian diets. Eggs are also a rare non-meat provider of B12, a crucial vitamin for the nervous system.
  • Greek Yogurt: Greek yogurt is not only high in protein but also contains calcium and probiotics. It's more concentrated in protein than its regular yogurt counterparts.
  • Cheese: Cheese varies in protein content, but options like Swiss, cheddar, and mozzarella rank among the top. Some cheeses also offer a good amount of calcium.
  • Milk: A glass of milk can provide 8 grams of protein per serving. It’s also an excellent source of calcium.
  • Pumpkin Seeds: Pumpkin seeds, also called pepitas, have a green color and are rich in essential nutrients such as vitamin K, phosphorus, and manganese. They’re also an excellent source of iron and great for vegans who don’t get enough iron. Eating 28g of pumpkin seeds can provide 7g of protein, 6g of Omega-6 fats, and 1.7g of fiber. 

Remember, balancing dietary proteins with other nutrient-dense foods is necessary for overall health and well-being. Your average vegetarian has many more protein sources, but Lacto-vegetarians and Ovo-vegetarians have a more limited menu. For personalized advice, always consult a registered dietitian.

Supplementing Your Diet with More Protein

Eating a balanced diet is vital for everyone's health, including vegans and vegetarians who need enough protein. Consuming a diverse range of proteins from different plant foods can provide all the essential amino acids you need. For the average person, the recommended protein allowance is 46 grams per day for women and 56 grams per day for men.

However, if you're trying to build muscle, the protein requirements are higher. Some sources suggest aiming for 0.6–1.0 grams of protein per pound of body weight. Here are some ways to supplement with more protein:

  • Spirulina: This blue-green algae is a gluten-free protein that provides all essential amino acids. It's also rich in vitamins like B1, B2, and B3.
  • Seitan: Made from gluten, the main protein in wheat, high-protein foods like seitan are a reliable source for many vegetarians and vegans. A serving size of 3.5 ounces has about 25 grams of protein.
  • Whey Protein (for vegetarians): Whey protein comes from milk. It's easily digestible and quickly absorbed into the body, making it a great post-workout supplement.
  • Plant-Based Protein Powders: These vegan protein powders come from peas, hemp, rice, or sunflower seeds and can be an easy way to boost protein intake.

Remember, while these supplements can help you meet your protein needs, they should not replace whole foods. Instead, they should complement a diet already rich in quality protein sources.
