This episode I describe science-supported nutrients for brain and performance (cognition) and for nervous system health generally. I describe 10 tools for this purpose, including specific amounts and sources for Omega-3 fatty acids which make up the "structural fat" of neurons (nerve cells) and allow them to function across our lifespan. I also review data on creatine, phosphatidylserine, anthocyanins, choline, glutamine and how they each impact brain function in healthy people seeking to reinforce and improve their cognition and in those combatting cognitive decline. I describe both food-based and supplement-based sources for these compounds, and their effective dose ranges based on peer-reviewed literature. Then I review the 3 factors: gut-brain signaling, perceived taste, and learned associations that combine with the metabolic and blood-sugar-elevating effects of food to determine what foods we seek and prefer. Amazingly, it's not just about what tastes good to us. Next, I explore how we can leverage the neural circuits of learned food preference toward seeking and enjoying the right foods for brain health and performance. I also review new data on non-caloric sweeteners and why consuming them with glucose-elevating foods can be detrimental, in some cases rapidly leading to insulin dysregulation. This episode covers more than 10 actionable tools for those seeking to improve and/or maintain brain function, and it explains modern neuroscience underlying of our sense of taste, our food seeking preferences and brain metabolism.
