This episode is brought to you by Rupa Health and Paleovalley.   Protecting your brain and cognitive function is not just for the elderly. It’s never too early to start protecting your brain, which is something we should all think more about as Alzheimer’s and dementia rates continue to rise. We can start with healthy lifestyle choices that affect diet, sleep, stress management, and more. The bonus of brain-healthy lifestyle choices like these is that they protect the health of your entire body as well.   In this episode of my new Masterclass series, I am interviewed by my good friend and podcast host, Dhru Purohit, about Alzheimer’s and dementia. We talk about early detection, contributors to cognitive dysfunction, foods that fuel the brain, and so much more. We also discuss how other factors, such as toxicity, sleep apnea, and even lack of community, affect brain health. Dhru Purohit is a podcast host, serial entrepreneur, and investor in the health and wellness industry. His podcast, The Dhru Purohit Podcast, is a top 50 global health podcast with over 30+ million unique downloads.
