- Ornish's regimen is more than mere diet, he claims. He is a stickler about incorporating at least 30 minutes of Moderate Exercise a day, or an hour three times a week, and using some kind of stress-management technique, which might include Meditation, massage, psychotherapy, or Yoga.
But wrong. Ornish goes to argue that protein and saturated fat increase the risk of mortality and chronic disease. As evidence for these causal claims, he cites a handful of observational studies. He should know better. These types of studies—which might report that people who eat a lot of animal protein tend to develop higher rates of disease—“only look at association, not causation,” explains Christopher Gardner, a nutrition scientist at the Stanford Prevention Research Center. They should not be used to make claims about cause and effect; doing so is considered by nutrition scientists to be “inappropriate” and “misleading... The other problem with Ornish’s antiprotein stance is that he lumps all animal proteins together.
