The Best Plant-Based Protein Sources

It’s a well-known fact that protein is essential for a healthy diet, with the Dietary Reference Intake (DRI) for protein being 0.8 to 1.0 grams of protein per kilogram of body weight. Proteins are made up of amino acids, and they are responsible for forming enzymes, hormones, antibodies and new tissues. Protein also transports nutrients in and out of cells.

Finding good sources of plant-based protein can seem challenging at first. But it’s actually a lot easier than you think. Many fruits and vegetables contain more protein than you might guess. Not only are plant based proteins cheaper, but they are also lower in fat and richer in fiber than most meat options.

We’ve listed some of the best plant based sources of protein and, we have to say, they all sound delicious!

Fruits and Vegetables

We don’t normally think of fruits and vegetables as good protein sources, but that is just a misconception and these fruits and veggies prove just that!


With a whopping 10 grams of protein, avocados have the highest protein content of any fruit. In addition to that, they are also a complete protein, providing the body with all 18 essential amino acids. One avocado also provides your body with vitamins A, C, E, K and B6, along with loads of potassium and healthy fat. Try the Avocado Apple Pie Green Smoothie. 


Although broccoli isn’t the first food that comes to mind when one thinks of protein, just one cup of this nutritious vegetable packs in 5 grams without any fat. When served alongside whole grains like quinoa or brown rice, broccoli can be turned into a source of complete protein. Unlike animal sources of protein, broccoli is rich in vitamins A and C. Try the Green Monster Smoothie.


Spinach contains 5 grams of protein per (cooked) cup. Low in calories, but rich in nutrition, this veggie is a great way to sneak more protein and fiber into your diet. Try the Creamed Spinach Smoothie –>

Beans and legumes are typically high in fiber, calcium, and iron, they are also inexpensive and an excellent source of protein.

Here is a list of beans and legumes which pack the most punch.


Rich in fiber, iron, phosphorous, and magnesium, soybeans are an excellent way to get your protein in. A one cup serving contains 28 grams of complete protein.


One cup of lentils provides about 18 grams of protein. Unlike the protein found in soybeans, the protein found in lentils isn’t complete. but that can easily be remedied by eating other protein sources throughout the day. Another benefit of lentils are that they are rich in fiber and are virtually fat-free.

Garbanzo beans

One cup contains14.5 grams of protein as well as ample amounts of fiber. Best of all, the proteins found in garbanzo beans include all eight of the essential dietary amino acids: isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan and valine.

Kidney Beans

These hearty beans are a good source of protein, containing 15 grams in one cup. When combined with a whole grain such as whole wheat pasta or brown rice, they provide protein comparable to that of meat, without the saturated fat. Instead, you get the blood sugar stabilizing and heart health benefits of the soluble fiber provided by these delicious legumes.
