Peter Attia: Cooking with Lard vs Seed Oils | Layne Norton, Ph.D.

Key Takeaways

• Replace saturated fats with lean protein sources or mono/polyunsaturated fats (like olive oil or avocado oil) to lower LDL cholesterol
• If avoiding seed oils, prioritize antioxidant-rich fats like olive oil for cooking over lard due to lower oxidation risk
• Limit deep-fried foods regardless of cooking oil – both seed oils and lard create harmful compounds when reused at high heat
• Don’t treat “healthier” fried foods (like lard-fried fries) as health foods – they’re still hypercaloric and inflammatory
• When reading nutrition studies, focus on the full text not headlines – most apparent contradictions resolve when examining methodology

Notable Quotes

“If you don’t want to consume seed oils, fine, but find something to displace the saturated fat in your diet with.”

“You have to understand, people think food companies care about which foods you buy. They just want you to buy.”

Bottom Line

For cardiovascular health, replace saturated fats with unsaturated alternatives, minimize fried foods regardless of cooking oil, and make dietary decisions based on complete scientific evidence rather than social media soundbites.
