It sounds like Dr. Chrispeel has made a conclusion for himself and maybe does not have the interest to see the health-enhancing differences from food grown by more vitalizing agricultural practices like Biodynamics offers. "There is substantial scientific evidence based on years of research indicating that biodynamic food is superior to organic. Crop yields are higher for biodynamic cultivation. Also, chemical analysis demonstrated among other things, better soil quality, higher organic content and microbial activity, more earthworms, better soil structure, and thicker top soil. Biodynamic produce has much more vitality and more concentrated nutrient value. Additionally, research indicates that biodynamic produce has better flavor, keeps fresh longer. Anecdotally, a strong connection exists between eating biodynamic food and increased vitality, reduced allergic reactions and improved overall health. Biodynamic agriculture brings healing to the earth from all the damage it has experienced and from human intervention putting nature out of balance. Even organic farming does not have the healing characteristics of restoring life. At the heart of Biodynamics lies recognition of basic principles at work in nature which form the basis through which balance and healing take place. Biodynamic farming means healing and revitalization of the Earth."
