I was listening to Drs. Brian & Anna Maria Clement (director of Hippocrates Health Institute) on Raw Summit 2. and he did some research and found that healthy people can eat a vegan, organic cooked diet that is 25% of their diet. What a relief! ... that explains why some health-type places advocate a diet that is 75% raw and 25% cooked, vegan. In his interview, he mentioned that people who were not in good health… and began a raw diet, could start introducing cooked food into their diet after two years.
I wish I knew where all this research was! I would like to learn more about this.
