Episode notes
Demand Primary Studies Not Just Doctor Opinions
- Expert opinions rank lowest in evidence hierarchy; demand primary sources and peer-reviewed studies.
- Greger recommends downloading PDFs and checking original papers rather than trusting conflicting doctor opinions.
Lower LDL As Much As Possible Appears Safe
- Very low LDL cholesterol appears safe and beneficial; lower is better for longer.
- PCSK9 inhibitors have driven LDL into single digits without the predicted hormone-related harms.
Buy Purple Kale For Anthocyanin Boost
- Buy purple (red) kale when available because anthocyanins add berry-like phytonutrients to greens.
- Michael Greger notes anthocyanins associate with improved cognition and combine benefits of berries and greens.
