When many people think about protein, images of animal products tend to pop into one’s head. Did you know though that every – yes, every – whole food contains protein? From your morning banana to your evening salad, finding plants packed with protein is easy to do. And not only is it easy to do, it’s easy for your body to use.
Plant-based foods are practically free from cholesterol, tend to be high in fiber, and are often alkalizing to the body. All animal products, on the other hand, are devoid of fiber, and are acidifying to the body, which causes calcium to be leached from your bones, as well as decreasing oxygen levels in the blood, and negatively impacting the digestive/lymphatic system.
You may have heard the ongoing debate about “complete” or “incomplete” protein and “food combining”, but be wary; these topics are steeped in misinformation and myth.
The term “complete protein” refers to foods that have all nine essential amino acids present in the correct proportion for our bodies to build protein with. The term “incomplete protein” refers to foods which have all the essential amino acids, but are simply low in one or more of them. This is called the “limiting amino acid”. While it’s true that most whole plant foods have one or more limiting amino acids and are thus “incomplete”, this shouldn’t send you running for a steak. Our bodies are brilliant, and every food that goes into your system must be broken apart and its nutrients absorbed. During the digestion process, amino acid chains from all sources are broken down and made ready for our bodies to use.
If you’re eating a good mix of fruits, veggies, grains and legumes, then your body simply collects what it needs from the “amino soup” that your digestion system has absorbed. There are a growing number of vegan bodybuilders, ultra marathon runners and award-winning athletes out there to prove that meeting your protein needs on a plant-based diet is simple and successful.
Since every whole food has protein in it, you have literally millions of great options to choose from when it comes to creating a balanced diet with the right percentage of protein for your body*. We’ve selected ten nutritious plants to get you started, for both their protein content and other health benefits. You may be surprised at some of the veggies, nuts and grains that made it onto the list.
*More is not necessarily better when it comes to protein. The Recommended Dietary Allowance (RDA) for the average, sedentary adult is only 0.8 grams per kilogram of body weight. Some healthcare professionals argue that this level is too high. No matter whose recommendation you choose to follow, the fact is that each person’s protein needs are different, but all can be met with a plant-based diet.

All the plants that have preceded this one on our list fall short in comparison to quinoa.* On its own it is a perfect protein and the king of all grains. It has the highest percentage of protein content at 16 percent per volume! This means that a measly ¼ cup (dry) quinoa has 6 grams** of protein. If you paired this grain with a couple of spears of asparagus and a beautiful cauliflower, broccoli and sprouted mung bean stir–fry, you would have an easy meal with 30 grams of protein or more!
* For those who are understandably concerned about the politics of Bolivian grown quinoa, rest-assured that there is such a thing as American-grown quinoa.
**This protein content information was obtained from a quinoa distribution company.
