The most frequent question I am asked as a vegan is, "How do you get enough protein?" Many people believe that usable protein can only be obtained from meat or soy products. This is not true. A wide variety of grains, legumes and vegetables contain more than enough soy for people, including elite athletes and body builders. The only nutrient that I need to supplement as a vegan is vitamin B-12 as it cannot be reliably obtained from plant sources.
In researching today's post about protein sources, I came across an article that says it all. The Physicians Committee for Responsible Medicine, an advocacy group committed to "compassionate and effective medical practice, research, and health promotion" has an excellent, inclusive article, "How Can I Get Enough Protein? The Protein Myth," available on their website at: http://www.pcrm.org/health/veginfo/protein.html
