As I explained in my last video, Alzheimer’s May Start Decades Before Diagnosis (http://nutritionfacts.org/video/alzheimers-may-start-decades-before-diagnosis), it’s never too early to start eating and living a brain-healthy lifestyle.

The reversal of blindness due to hypertension and diabetes with Dr. Kempner’s rice and fruit diet demonstrates the power of diet to exceed the benefits of the best modern medicine and surgery has to offer. Subscribe to NutritionFacts.org's free e-newsletter and receive a recipe from Dr. Greger's brand-new cookbook, The How Not to Diet Cookbook: https://nutritionfacts.org/subscribe/ I documented the extraordinary Kempner story previously in Kempner Rice Diet: Whipping Us Into Shape (http://nutritionfacts.org/video/Kempner-Rice-Diet-Whipping-Us-Into-Shape) and Drugs and the Demise of the Rice Diet (http://nutritionfacts.org/video/drugs-and-the-demise-of-the-rice-diet/). The reason I keep coming back to this is not to suggest people should go on such a diet (it is too extreme and potentially dangerous to do without strict medical supervision), but to show the power of dietary change to yield tremendous healing effects. The best way to prevent diabetic blindness is to prevent or reverse the diabetes in the first place. See, for example: • Lifestyle Medicine Is the Standard of Care for Prediabetes (http://nutritionfacts.org/video/lifestyle-medicine-is-the-standard-of-care-for-prediabetes/) • How to Prevent Prediabetes from Turning into Diabetes (http://www.nutritionfacts.org/video/how-to-prevent-prediabetes-from-turning-into-diabetes) • Plant-Based Diets and Diabetes (http://nutritionfacts.org/video/plant-based-diets-and-diabetes/) Why wouldn’t a diet of white rice make diabetes worse?
