What is the #1 nutrient deficiency driving brain fog, memory loss, and even dementia? According to neurologist Dr. Dale Bredesen, one of the most common and overlooked deficiencies is choline, a critical nutrient required to build the memory neurotransmitter acetylcholine. In this powerful episode, Dr. Bredesen joins Dr. Mark Hyman to discuss why so many of us are deficient not only in choline but also in a host of other critical brain nutrients like B vitamins, vitamin D, zinc, and magnesium. He explains the "triple whammy" of modern life that's robbing us of these nutrients: depleted soils, processed high-sugar foods, and a lack of essential fiber and phytonutrients. Discover why simply correcting these deficiencies is a cornerstone of Dr. Bredesen's groundbreaking protocol, which has been clinically shown to reverse cognitive decline. This conversation provides a roadmap for feeding your brain, protecting it from toxins, and activating its innate healing systems. In this episode, you will learn: The #1 most common nutrient deficiency for brain health and where to find it in your food.
