Complementary Protein Combinations: A Recipe For Building a Stronger Diet

Protein is an important part of any diet, but you’re probably tired of being asked how you get enough protein as a vegan.

Truth is, it’s pretty easy to get enough protein as a vegan. But are you getting all of the right kind of protein every day to maintain lean muscle mass and fuel your health, longevity, and fitness goals?

The complementary protein combinations in this article will make sure you are…easily! So you can continue to enjoy delicious vegan meals without worry!

This is not just for vegans by the way – complementary proteins are great for anyone who wants more protein in their diet.

What is Protein?

Protein is made up of amino acids. There are 20 amino acids in total; 9 essential amino acids (EAA) and 11 nonessential amino acids.

Nonessential means that our bodies make them on our own, so we don’t have to provide them in our diet.

Essential means that we can’t make them on our own so we have to eat them.

These 20 amino acids are used to make all of the structures in our bodies. In fact, every cell in your body contains protein! It’s that important.

What Are Complementary Proteins?

Not all plants have all 9 essential amino acids in adequate amounts. Any amino acids that a food is low in are called limiting amino acids. The limiting amino acids are lysine, threonine, methionine, and tryptophan.

If we have a food that is low in one amino acid (AA), we pair it with a food that has that limiting amino acid in adequate amounts. In this way, the two foods complement each other, creating a “complete protein.”

This is incredibly easy to do! It’s almost as if nature created foods that are delicious together and complement each other.

We’ll talk more about that in a bit.

Is It Important to Make Complementary Proteins in One Sitting?

Nope.

That was the traditional thought, but it’s outdated.

The traditional view was that plants were. source of “incomplete protein.” To make them complete you had to eat complementary plants at the same time. I’m not sure how vegetarians survived with this view.

Animal protein, on the other hand, was considered to be superior because it contains all of the amino acids in abundance.

Recent evidence shows that this is not true and it does not really matter when complementary proteins are consumed as long as they do work as complementary proteins and are eaten within a day or two of each other.

Creating Complementary Proteins

There are two major groupings that easily create complete proteins:

grains + legumes

Nuts and seeds + legumes

Or use this chart!

This chart lists some common foods, their limiting amino acid/s, and what foods to pair them with to create complete proteins.

Before we dive into putting these together, let’s define what legumes, grains, and nuts and seeds are.

What Are Legumes?

Legumes include beans, lentils, peas, peanuts, and soybeans.

Adding legumes to your diet has been shown time after time over recent years to offer many health benefits, including improved heart function and reduced risk for type 2 diabetes.

Legumes are typically low in methionine, but high in lysine and tryptophan.

What Are Grains?

Grains are staple crops used for food around the world. The three major cereal grains are wheat, corn, and rice.

But there are so many more that you may or may not have heard of. Quinoa, millet, sorghum, buckwheat, amaranth, and oats are all grains!

Grains are typically low in lysine, threonine, and cysteine (which is not an essential amino acid), but are high in methionine.

What Are Nuts And Seeds?

Nuts and seeds represent a diverse group of plants that contain small seed-like kernels inside a shell, with the exception of peanuts which grow underground like beans and are actually a legume.

Sunflower seeds, pumpkin seeds, walnuts, pistachios, and chia seeds are just a few of the varieties you can incorporate into your diet.

Nuts and seeds are typically low in lysine, but are high in methionine.

Nuts and seeds are also packed with protein, fiber, vitamins, and minerals. If you’re looking to eat healthier, look no further! If you’re not counting calories, add these to every meal or as a major part of your daily snacks.

Why Are Grains With legumes Such a Powerful Pair?

As we’ve discussed, there are nine essential amino acids, meaning we have to give them to our bodies through our diet. Your body needs enough of each of the 20 amino acids to create structures throughout your body.

Plants actually have all of the essential amino acids (EAA), but most have one or two that are short supply.

Grains and beans are perfect here! For example, grains are low in lysine but high in methionine, while legumes have the opposite profile of being high in lysine and lower in methionine.

By eating beans and grains together, the strengths of one makes up for the deficiencies of the other, making a complete protein.

Remember that these do not have to be eaten at the same time! You could have oatmeal for breakfast and beans with dinner. Still counts!

But legumes and wholegrains go so well together, that we might as well look at some delicious recipes.

7-Layer Bean Dip With Chips (okay, not super healthy, but incredible if you’re throwing a party!)

Nuts and Seeds With Legumes:

Nuts or seeds paired with legumes also make complementary proteins.

I find these combinations to be less natural, on their own, than pairing legumes and grains. Not many think to have a meal of beans and walnuts. Really, outside of mixed nuts (assuming they have peanuts as part of the mix), it can be difficult to think of tasty options.

But over the years I’ve gotten creative and come up with some amazing pairings in my never-ending quest for fitness.

Or you can just toss some nuts or seeds in with your grains, smoothies, or salads and call it good.

Amazing Nuts & Seeds With LegumesCombinations and Recipes:

Look, if you’re having some nuts as a snack or adding seeds to smoothies or salads throughout the day, you’re covered.

Plants That Are Complete Proteins By Themselves

Not all plant proteins are lacking in amino acids. Some are complete all by themselves!

Soy, amaranth, quinoa, hemp hearts, and chia seeds all have plentiful amounts of each of the nine essential amino acids.

Soy is my vegan plant protein power food! It contains all the essential amino acids and is also a good source of healthy fats and phytochemicals (plant chemicals that may be good for you).

You may find it in processed, vegan foods, but It’s usually served as tempeh or tofu. Soy milk is a popular replacement for milk.

Edamame is another easy source of soy protein.

Amaranth, quinoa, hemp hearts, and chia seeds are also complete proteins.

Plant Protein Pairings Conclusion

Plant-based complementary proteins are the perfect answer to overcoming deficiencies in amino acids. There are plenty of amazing, complementary, high-protein recipes out there to keep you healthy and chasing your fitness goals. Don’t worry about having to eat plain old beans and rice over and over again!
