From Dr John McDougall:
'People worry more about protein in their diet than any other nutrient. The obvious truth is: there is enough protein in plants to grow an elephant, horse, or hippopotamus. Certainly there is enough protein to grow relatively small people. Furthermore, all plants contain all of the amino acids in proper balance for ideal human growth. In other words, it is impossible to make up a diet deficient in protein or individual amino acids from any unrefined starches (rice, potatoes) and vegetables. You must get over this common myth in order to comfortably follow a diet that is best for you and the family. The only real problems with protein come from eating too much.'
