WHY YOUR BRAIN NEEDS CHOLESTEROL; CHOLESTEROL IN THE BRAIN IS INVOLVED IN THE COMMUNICATION PROCESS FOR NEUROTRANSMITTERS, SUCH AS DOPAMINE AND SEROTONIN. IT MAKES UP THE MAJORITY OF MYELIN, THE WHITE FATTY SHEATH THAT PROVIDES A PROTECTIVE COATING ON NEURONS TO INCREASE THE BRAIN’S PROCESSING SPEED. AND THEY PLAY A ROLE IN THE DEVELOPMENT OF “LIPID RAFTS,” MEMBRANES THAT ARE INVOLVED IN BRAIN CELL SIGNALING. BOTTOM LINE? APPROXIMATELY 60% OF THE SOLID WEIGHT OF THE BRAIN IS FAT, SO YOU NEED HEALTHY LEVELS OF CHOLESTEROL FOR OPTIMAL FUNCTION.
