Bless you for being a caretaker! The last year I've been learning about food as medicine. One of the most enlightening masterclasses I watched on the internet was by Drs. Dean and Ayesha Sherzai on how to prevent and reverse dementia and alzheimer's through proper nutrition and lifestyle decisions. They wrote a book that is on the NY Times bestseller list that I'd highly recommend assuming it is as informative as their masterclass: The Alzheimer's Solution: A Breakthrough Program to Prevent and Reverse Symptoms of Cognitive Decline at Every Age. Their work is so inspiring!
