On March 8, members of the CMJ Masterpass joined me in a live Zoom meeting to ask me anything about nutrition, and here's the full recording!

We talk about things like:

• What to do if zinc causes nausea?
• When on a ketogenic diet, it is a problem if ketones are going up to 5 to 6 millimoles per liter?
• What if I'm on a ketogenic diet, and I can't get my ketone levels up higher than 1 millimole per liter when my primary reason for being on the ketogenic diet is that I'm trying to control blood glucose better?
• Advice for what to do after suffering a transient ischemic attack.
• Nutrients important for neuroregeneration.
• What causes sinus congestion, and what can help?
• Nutrition for children with ADHD.
• Nutritional recommendations for MTR and MTRR polymorphisms.
• Why the main problem with hyperglycemia is not glucose but rather advanced glycation end products, and why the main determinant of advanced glycation end products is low insulin signaling.
• Does the difference between cyanocobalamin, hydroxocobalamin, and methylcobalamin matter, and does the difference between sublingual, oral, and intramuscular injection matter?
• Could fat malabsorption be driven by genetic polymorphisms that lower activity the PEMT enzyme? And could fat malabsorption in general be causing not only mineral deficiencies but also hyperabsorption of oxalate from foods?
• Why am I always sneezing first thing in the morning?
• What if I cannot get my ferritin up and supplementing iron actually raises my serum iron well above the normal range?
• A rant on why many people use "MTHFR" to slap a label on their health problems.

All this and much more!
