When I tell people I`m vegetarian, often the first question out of their mouths is, “Ok, so where do you get your protein?” As soon as I hear this question, I know that I`m dealing with someone who doesn`t know very much about plants. The idea that plant foods are devoid of protein is nothing but a myth. Plant foods are generally rich in protein. For example, lettuce gets 34% of its calories from protein, and broccoli gets 45% of its calories form protein. Cauliflower is 40%. Celery is 21%. Beans range from 23% to 54% depending on the variety. Grains are 8% to 21%. Fruits are the lowest at around 5-8% on average. If you wanted to suffer from protein deficiency, you`d either have to starve yourself, or you`d have to eat a really unbalanced diet like nothing but low-protein junk foods and certain fruits.
