Michael Greger: Are Plant Sterols Effective for Lowering Cholesterol?

Key Takeaways

• Eat fiber-rich foods like oatmeal to trap cholesterol in the digestive tract and flush it out.
• Consume phytosterol-rich foods (nuts, seeds, vegetables, legumes) to block cholesterol absorption—aim for 2–3 g/day for optimal LDL reduction.
• Prioritize plant-based foods to naturally increase phytosterol intake (modern diets provide only ~300 mg/day vs. ancestral ~1 g/day).
• Combine phytosterols with lifestyle changes for a 10% LDL drop, reducing heart disease risk by 10–20% over time.

Supplements & Protocols Mentioned

• Phytosterols: 2–3 g/day for LDL reduction (via foods or supplements).

Notable Quotes

“Phytosterols compete with cholesterol to squeeze in through [intestinal] receptors… so more cholesterol ends up in the toilet instead of our bloodstream.”

Bottom Line

Boost phytosterol intake to 2–3 g/day through nuts, seeds, and plants, and pair with fiber to lower LDL cholesterol effectively.
