Getting your daily protein from plant-based sources is not only better for your health, but also more sustainable and better for the environment.

Unfortunately, many people are still under the impression that plant proteins are not "complete" and do not contain all the amino acids (the building blocks of proteins) that our body needs.

This is actually not the case. There are many complete plant protein sources out there that not only contain all the essential amino acids, but also many other nutrients that our body needs and contribute to our health.

In this article we have listed 10 best plant-based protein sources that you should be eating.

1. Spirulina (100 grams = 60 grams of protein)

This blue-green alga is not only a great complete source of protein, but also contains a lot of vitamins, minerals and essential fatty acids that your body needs. Spirulina has an anti-inflammatory effect and is rich in antioxidants that protect your body against harmful substances and free radicals that can cause damage to your body and contribute to many diseases.

Spirulina contains all of the essential amino acids and is one of the richest sources of protein on the planet with a protein content of about 60 to 70 percent.

Spirulina is often available as a powder that you can add to smoothies and soups to give it a good protein boost. One tablespoon of spirulina contains about 5 grams of complete plant-based protein.

A portion of cooked quinoa has about 8 grams of protein and can be used in breakfast bowls, salads or as a substitute for rice.

5. Buckwheat (100 grams = 9 grams of protein)

Buckwheat, like quinoa, is a "pseudo cereal". It contains slightly less protein than quinoa, but it also contains all the essential amino acids and is an excellent source of good carbohydrates, fibre, vitamins and minerals such as magnesium, phosphorus, iron, manganese, copper, zinc.

Buckwheat is very nutritious and easily digestible. You can use buckwheat in a salad or a risotto and it is also often used as (gluten-free) flour in baking.

6. Pumpkin seeds (100 grams = 19 grams of protein)

Nuts and seeds are a good plant-based source of protein that also contain lots of healthy fats and other nutrients that contribute to good health.

When you start eating a more plant-based diet, than its a good idea to start eating more nuts and seeds.

A few tablespoons of pumpkin seeds contain about 7 grams of complete protein.

7. Nutritional yeast (100 grams = 50 grams of protein)

Nutritional yeast is deactivated yeast that is often sold as flakes or as a powder and is available in most health food stores.

It is a complete source of protein and also contains many B vitamins (B1, B2, B3, B6) and folic acid. Some brands have added vitamin B12, a very important vitamin for people that eat a complete plant-based diet.

Nutritional yeast has a nut-like flavour and is often used in savoury dishes and as a substitute for cheese, but contains much less fat and calories than cheese.

This allows you to easily add some extra protein to your meal without adding a lot of extra calories.

8. Soybeans (100 grams = 36 grams of proteins)

Soy is a healthy complete source of protein that's almost identical to animal protein sources and is therefore an excellent replacement for meat, dairy and other animal products.

Soy is widely eaten in Asian countries (tofu, tempeh, miso) and is often used in many plant-based foods such as soy yoghurt, soy milk, meat substitutes and other plant-based products.

They are easy to prepare and easy to add to soups, salads, vegan chilli and curry dishes.

Beans and other legumes generally contain a bit less essential amino acids than animal products (except for yellow split peas and soy beans).

But if you also add some grains like rice and whole wheat to your diet, you can ensure that your body gets all of the essential amino acids.

For example, a lentil curry with rice or quinoa, whole wheat pita bread with hummus or a slice of whole wheat bread with some natural peanut butter.
