When it comes to protein intake, plant-based diets are often seen as lacking. A common misconception is that vegetarians and vegans have a hard time getting complete proteins in their diet without the help of supplements or animal products. However, this couldn’t be further from the truth. In fact, there are plenty of legumes that are complete proteins, and can provide all the essential amino acids your body needs.
Some of the most popular and widely available complete protein legumes include chickpeas, lentils, and black beans. These humble ingredients can easily be incorporated into meals and snacks to provide a healthy and satisfying source of protein. Not only are legumes a great source of plant-based protein, but they also offer a host of other benefits such as fiber, iron, and other important nutrients.
So why do legumes, such as chickpeas, lentils, and black beans, provide complete proteins? The answer lies in their amino acid profiles. While most plant-based foods lack certain essential amino acids, legumes have a unique combination that makes them a complete protein source. This means that legumes can provide all the amino acids your body needs in one simple and delicious package. So, next time you’re looking for a healthy and easy source of protein, don’t overlook the power of legumes!
What are legumes?
Legumes are a family of plants that includes beans, lentils, peas, and chickpeas. They are high in protein, complex carbohydrates, fiber, and various vitamins and minerals, making them a healthy and nutritious food choice. Legumes have been used as a staple food source for centuries in many cultures around the world. They are versatile and can be incorporated into many different types of dishes, ranging from soups and stews to salads and burgers.
Why are proteins important?
Proteins are one of the three macronutrients essential to human health, alongside fats and carbohydrates. They are composed of amino acids, which are used to make muscles, bones, skin, hair, and other tissues in the body. Protein is required by the body for growth and maintenance, and it plays a crucial role in many biological processes such as DNA replication, enzyme production, and hormone regulation.

The benefits of plant-based protein sources
Plant-based protein sources – including legumes – offer a number of health benefits. For starters, plant-based protein sources are generally lower in saturated fat and higher in fiber compared to their animal-based counterparts. Consuming high amounts of animal protein has been linked to a number of health problems, including heart disease, certain types of cancer, and kidney disease.
Furthermore, plant-based protein sources are generally more environmentally sustainable than animal-based sources. Animal agriculture is a major contributor to greenhouse gas emissions, and it requires more land, water, and energy to produce a pound of beef compared to a pound of lentils. By choosing plant-based protein sources like legumes, we can help reduce our carbon footprint and support sustainable agricultural practices.
The protein content of legumes
While legumes are an excellent source of protein, it’s worth noting that they are not a complete protein source on their own. This means that they do not contain all nine essential amino acids that our bodies need. However, by pairing legumes with other plant-based protein sources such as grains or nuts, we can create complete protein meals. For example, a dish of lentils and rice or whole-grain bread with peanut butter contains all nine essential amino acids.
| Legume | Protein (per 100g) |
|---|---|
| Lentils | 9g |
| Black beans | 8.86g |
| Chickpeas | 9g |
As you can see from the table above, lentils, black beans, and chickpeas are all good sources of protein, with about 9 grams per 100 grams of cooked legumes. By incorporating these and other plant-based protein sources into our diets, we can meet our daily protein needs while also taking advantage of the many health benefits associated with a plant-based diet.
What are complete proteins?
Proteins are essential macronutrients that are composed of amino acids. They are necessary for various bodily functions such as building and repairing tissues, producing enzymes and hormones, and maintaining a healthy immune system. Complete proteins are a type of protein that contains all nine essential amino acids that the body needs but cannot produce on its own. These essential amino acids must be obtained through food sources.
Meat, dairy, and eggs are commonly known as complete protein sources. However, for vegetarians and vegans, it is essential to know which plant-based foods contain complete proteins to ensure that they receive all essential amino acids in their diet.
Which legumes are complete proteins?
- Soybeans: Soybeans are considered to be the only plant-based complete protein source. They are one of the few plant sources that contain all the essential amino acids in adequate amounts.
- Lentils: Lentils are not complete proteins but can be paired with other foods to form complete protein sources. When lentils are combined with grains like rice or quinoa or nuts like almonds, they form a complete protein source.
- Chickpeas: Chickpeas are not complete proteins but can be combined with grains to form a complete protein source. When chickpeas are paired with foods like rice or quinoa, they form a complete protein source.
Pairing legumes with other foods to form complete protein sources
Plant-based proteins can be paired with other foods to form complete protein sources. This is known as “complementary protein” or “protein combining.” When combining plant-based proteins, it is essential to consume them in the correct ratios to ensure that all essential amino acids are being obtained.
For example, when lentils are paired with rice, the ratio should be two parts rice to one part lentils. This ratio ensures that all essential amino acids are being obtained. Similarly, when chickpeas are paired with quinoa, the ratio should be one part chickpeas to one part quinoa.
Comparing legumes and other complete protein sources
Although legumes provide an excellent source of protein, they are not as protein-dense as other complete protein sources like meat, eggs, and dairy. Below is a comparison table of the protein content in different complete protein sources.
| Protein Source | Protein Content per 100 grams |
|---|---|
| Chicken breast | 31 grams |
| Egg | 13 grams |
| Salmon | 25 grams |
| Greek yogurt | 10 grams |
| Soybeans | 36 grams |
Despite this, legumes are still an excellent source of protein that can be incorporated into a healthy and balanced diet. Incorporating different types of legumes and pairing them with complementary foods is a simple and effective way to obtain all essential amino acids and increase protein intake.
Which legumes contain all essential amino acids?
Legumes are a great source of plant-based protein and are an essential part of a healthy diet, particularly for vegetarians and vegans. While most legumes are not complete proteins and lack essential amino acids, some legumes contain all nine essential amino acids, making them a complete protein.
- Soybeans: Soybeans are one of the few plant-based foods that contain all nine essential amino acids, making them an excellent source of complete protein. They can be enjoyed in various forms such as tofu, tempeh, miso, and soy milk.
- Hempseeds: Hemp seeds are a great source of high-quality protein and contain all essential amino acids, including omega-3 and omega-6 fatty acids. Hemp seeds can be added to smoothies, sprinkled on salads, or used in baked goods.
- Quinoa: Although quinoa is not a legume per se, it is a seed that is often used like a grain in cooking. It is a complete protein and contains all nine essential amino acids. It is versatile and can be used in salads, as a breakfast porridge, or as a replacement for rice.
Other legumes may contain a high amount of protein but are not complete proteins because they lack certain essential amino acids. For example, black beans and kidney beans are high in protein but do not contain enough methionine to make them complete proteins. However, when combined with grains such as rice, they form a complete protein. Therefore, it is important to ensure that you consume a variety of legumes and grains to get all the essential amino acids your body needs.
| Legumes | Complete Protein? |
|---|---|
| Soybeans | Yes |
| Hempseeds | Yes |
| Quinoa | Yes |
| Black beans | No |
| Kidney beans | No |
Overall, incorporating legumes that are complete proteins into your diet can have many health benefits, including reducing the risk of heart disease, diabetes, and other chronic illnesses. Experiment with different legumes and grains to find the perfect combinations that meet your nutritional needs and satisfy your taste buds.
