Nutrition in Neuroscience Part 2 | Mastering Nutrition #54

Part 2 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 NEUROTRANSMITTERS!

Our Native American ancestors believed that eating the organs from a healthy animal would support the health of the corresponding organ of the individual. Ancestral Supplements has a nose-to-tail product line of grass-fed liver, organs, "living" collagen, bone marrow and more... in the convenience of a capsule.

Ample is a meal-in-a-bottle that takes a total of two minutes to prepare, consume, and clean up. It provides the right balance of nutrients needed for a single meal, all from a blend of natural ingredients. Ample is available in original, vegan, and keto versions, portioned as either 400 or 600 calories per meal. I'm an advisor to Ample, and I use it to save time when I'm working on major projects on a tight schedule.
