On today’ show, we had Morley Robbins on once again to discuss vitamin A (retinol) deficiency and the consequences of that including autism, circadian rhythm dysfunction, and HPA axis (our stress response pathway) dysfunction.  We also discuss how taking vitamin D supplements diminishes your vitamin A levels.  Other topics we cover are:
-what are normal blood levels of vitamin D
-how do labs like Quest determine what “normal” is?
-oxidized LDL is a better predictor of heart disease than Total Cholesterol and LDL
-the need to eat real food with good fats like butter, eggs and animal fats
