Vegan Protein Sources

By Thomas Stearns Lee, NMD

Plant foods contain the same eight amino acids as animal foods do, only in differing amounts.  As long as you are getting enough calories from a healthy diet, plant foods give you all the amino acids you need, by themselves or in combination with one another.

Foods listed below are considered complete proteins, meaning they contain all of the essential amino acids:

  • Nuts

  • Soy foods, such as tofu, tempeh, miso, and soy milk

  • Sprouted seeds -- each type of sprout has differing proportions of nutrients, so it's best to eat a variety of them

  • Grains, especially amaranth and quinoa, are highest in protein and are high-quality proteins

  • Beans and legumes, especially when eaten raw

  • Spirulina and chorella (blue-green algae), which are over 60 percent protein
