Do YOU Get Enough Protein?

How much protein do we really need?

“Do you get enough protein”? or “where do you get your protein”? Probably every vegan, and many vegetarians, hear these questions so often that it has become the ultimate joke – it’s even a tee shirt. I have listened to this question so many times. I used to say, “plants”, and list some of the plant protein sources like legumes, and then explain that even a banana has 1.3 grams of protein (clearly vegan protein is easy to find). Protein, what our bodies need, and our dietary sources of it, is a complex subject. This post is meant to give you some tools to help you answer these inevitable questions in a generally informed manner.

Plant-Based Nutrition (or “what I did this winter”)

One of the best things I did was to become certified in Plant-Based Nutrition through eCornell. While I learned so many things, the course changed my response to questions about protein. I now ask, “Do you know how much protein you need every day?”.
Having this knowledge allows me to have a much more thoughtful discussion, and it tends to diffuse the tension and defensiveness that vegans and non-vegans alike can fall into when the subject of protein comes up.

What is Protein For?

Protein is the only nitrogen source in our diet, except for some nucleic acids. Protein must be consumed to replace the amount of nitrogen excreted by the body during normal protein metabolism. The Estimated Average Requirement (formerly called the Minimum Daily Requirement) for replacing the broken-down proteins and excreted as nitrogen end-products has been scientifically determined to be 0.5-0.6 grams of protein per kilogram of body weight per day. That’s it.

To accommodate deviations in the general population in terms of protein requirements, the RDA, or Recommended Dietary Allowance, is increased to 0.8 grams of protein per kilogram per day. The RDA is not the minimum. The RDA already has increased protein requirements built in. This (already slightly increased) level represents about 8-10 percent of total diet calories. Think about it. If you were eating a 2000 cal/day diet, you would only need approximately 200 protein calories. A six-ounce piece of cooked, boneless, skinless chicken breast (which we don’t eat, of course) has 222 calories from protein (277 calories total). Clearly, based on these numbers, for meat eaters, it’s not just “get enough protein,” but that they are getting far in excess of the amount of protein their bodies require. As a matter of fact, there are serious issues with excess protein!

Amino Acids?

You may even hear people talking about “essential amino acids”, “complete protein”, and “food combining”. Here it is really quick: protein is made of amino acids, and there are nine amino acids that your body needs from food to fully synthesize protein (that banana mentioned above happens to have all nine, and more). The same amino acids found in animal “foods” are available in plants. Our bodies also have the amazing ability to utilize the amino acids provided by a whole food, plant-based diet to synthesize new protein – making it easy to get enough protein (and more!). Food combining at a given meal once considered to be essential for a “complete protein”, is unnecessary.

It’s Easy to Get Enough Vegan Protein

If an average woman weighs around 130lbs (59 kgs), she only needs about 48 grams of protein per day. A man weighing 170lbs (77 kgs) needs about 62 grams of protein.

That piece of chicken mentioned above has 54 grams of protein!

Consider some great vegan protein sources:

  • 1 cup green peas = 8 grams
  • 1 cup of cooked oatmeal = 4 grams
  • 1 cup of cooked lentils = 18 grams
  • 1 cup cooked black beans = 15 grams
  • 1 cup of cooked broccoli =2.6 grams
  • 1 cup of cooked brown rice = 5 grams
  • 1 cup of cooked quinoa = 8.1 grams
  • 1 cup soy milk = 7 grams

Its easy to get enough protein - and be even healthier - on a vegan diet

It is easy to demonstrate with these examples that it is very easy to meet the body’s protein requirement with plant sources, all of which offer the additional benefits of being high in fiber and nutrients, things that everyone can agree on as essential to a healthy diet.

I hope that you will also find this information helpful in terms of your body’s protein requirements and inform and answer the questions of non-vegans who are considering a plant-based diet but are concerned that they will not be able to get enough protein.

  1. […] Paying attention to protein will aid in maintaining good health while you eat a vegan diet, as you need to locate quality plant-based sources of protein. Fortunately, countless vegan foods are surprisingly high in protein, including legumes and beans like peas or lentils, nuts, seeds, and more. Adding these foods to your daily diet will benefit your body and mind far more than you could ever expect, as protein is an essential compound for many different tasks, including growth and repair. You don’t need to go crazy, or obsess about it—read more about sensible protein intake in our recent post. […]

  2. […] Protein is important for a number of reasons. It aids growth and development in children and teens, which is essential. As well as this, there is protein in every single cell in your body, and if there’s something wrong with the cell, then it’s going to need protein to repair it. This is why you need to make sure that you’re getting this from somewhere. As someone living the vegan lifestyle, the traditional option for protein goes out the window. So, it’s time to improvise then!  […]
