“ The phytochemicals, antioxidants, and fiber- all of the healthful components of plant foods- originate in plants, not animals. If they are present, it is because the animal ate plants. And why should we go through an animal to get the benefits of the plants themselves? To consume unnecessary, unseemly, and unhealthy substances, such as saturated fat, animal protein, lactose, and dietary cholesterol, is to negate the benefits of the fiber, phytonutrients, vitamins, minerals, and antioxidants that are prevalent and inherent in plants. ”
