Part 4 of how NUTRITION has a HUGE impact on your BRAIN! Everything in your brain is something you ate, something you made from something you ate, or, in a few cases, something your mother ate. Nutrition impacts your mental and emotional health, the function of your five senses, and your conscious and unconscious control over your body movements. Join me as I lead you in a safari through the textbook, “Neuroscience,” pointing out along the way all the interesting connections to nutrition. Listen in for part 2 on the COGNITIVE FUNCTIONS! Mental and emotional health, cognitive performance, and sleep! Ads This episode is brought to you by Ancestral Supplements' "Living" Collagen.
