Am I Getting Enough Protein on a Plant-Based Diet?

COMMON MISCONCEPTION

It’s a common misconception that anyone eating a plant-based diet is deficient in protein. What’s not so well-known is that there are a plethora of options when it comes to excellent sources of plant-based protein.

The Recommended Dietary Allowance (RDA) for protein, is 0.8 grams of protein per kilogram of body weight. (1) The RDA is the amount of a nutrient you need to meet your basic nutritional requirements. To calculate, multiply your weight in pounds by .36, or use this online protein calculator.

This amount of protein is easily met if you're eating a well-rounded plant-based diet with lots of veggies, whole grains, legumes, nuts, and seeds.

How Much Protein?

However, how much protein is needed for optimal health may also depend on your age.

This data comes from a study analyzing the self-reported calorie intake of more than 6,800 U.S. adults ages 50 and over who consumed protein: high (20% or more), moderate (10-19%), or low (less than 10%).

We should be cautious about this kind of data because people report their intake, and memory can be tricky and sometimes elusive. That said, the findings are very interesting.

If you're 50-65 years old, eating more protein, especially from animal sources, had a "75% increase in overall mortality and were four times more likely to die from cancer during the following 18 years than those in the low protein group. The moderate-protein diet was associated with a 3-fold increase in cancer mortality compared to the low-protein diet." (2)

The good news is that the associations were only found when the proteins were derived from animal rather than plant sources. Another good reason to keep eating a plant-based diet. Not so if you're 65 or older.

Protein Needs if You're 65 or Older

The recommendation for those 65 & older is a little different.

According to an article from the National Institutes for Health, "In participants ages 65 and older, those who consumed high amounts of protein had a 28% lower risk of dying from any cause and a 60% lower risk of dying from cancer. These associations weren’t influenced by whether the protein was derived from animal or plant sources."

What is the sweet spot for protein consumption if you're 65 or older?

1.0 to 1.3 g/kg/day dietary protein combined with twice-weekly progressive resistance exercise reduces age-related muscle mass loss

It's for 1.0 to 1.3 times your weight in kilograms per day, as opposed to the recommendation for those younger of 0.8 per kg listed above. So if you weigh 140 lbs., multiply 140 x .454 to get your weight in kg, which is about 64. Then multiply 64 x 1.2 (and 1.5)  to get 76.8 - 96gm of protein daily.

Watch Dr. Michael Greger's video, Increasing Protein Intake After Age 65, to learn more about increasing protein intake after age 65.

If this is you, you may want to increase the amount of protein in your diet by adding more beans and lentils, tofu and tempeh, and seitan, a gluten source of protein.

Sources of Plant-Based Protein

Below is a list of vegetables, legumes, seeds, and other foods that, when included regularly in your diet, will help provide you with ample protein. I’ve listed them from highest to lowest. That said, the last item on the list, guava, has 4 grams of protein in a single cup! Seitan, not listed in the chart below, has 47 gms of protein per cup and three tablespoons.

How to Cook with Plant-Based Protein

There are so many different ways to include these foods in your diet every day. Hemp seeds, chia seeds, and flax seeds can be sprinkled on salads and added to smoothies. Dry-roasted soybeans, edamame, pistachios, pumpkin seeds, and squash seeds can also be used in your trail mix!

Learn about cooking with tempeh, seitan, and tofu in these articles. Tempeh, tofu, beans, lentils, quinoa, and oats are included in many of my recipes. And, of course, vegetables can be eaten raw, roasted, or steamed, not to mention used in soups, stews, and salads! You can even dehydrate green peas and grind them into a powder, and you’ll have a potent protein powder for your smoothies and soups.

The point is, get creative with your recipes and stock your kitchen with a nice assortment of these protein staple foods, and you won’t have to worry about meeting protein requirements.
