On March 4, you joined me in a live Zoom meeting to ask me anything about nutrition, and here’s the full recording!

We talk about things like:

How much spinach, broccoli, and kale is too much?
Can frozen vegetables be trusted for their folate?
Do cooked legumes lose folate when frozen?
I go on an extended rant about the harm done by exaggerating the harms of synthetic folic acid.
We use labs to identify a probable genetic defect in glutathione synthesis.
When to think about supplementing with calcium.
When a drug makes histamine intolerance and blood sugar dysregulation collide.
My thoughts on root canals.
Should you take leucine to gain muscle mass, or just eat protein?
A GREAT discussion on how our detoxification system evolved to handle fruits and vegetables, and why eating them can help us out through the principle of "hormesis."
Could low LDL levels compromise female fertility?

All this and much more!
