What an amazing week of important ideas to share. Dr. Kahn discussed a major study from the Cleveland Clinic showing that the sweetener Xylitol can cause blood clotting. Beware. Can plants help maintain and build muscle? Dr. Kahn says yes. Viagra helps blood flow to the brain—who knew? And colchicine shows benefits again, this time in stroke and TIA populations.

The main topic is the landmark study published by Dean Ornish, MD, and others, showing that a plant-based diet and supplements combined with lifestyle changes can reverse early Alzheimer's disease in many patients. This is an outstanding contribution that can be adopted right away. Dr. Kahn also mentioned a B complex vitamin he uses at the Kahn Center, which can be found here.
