Cooking Oils: Myths and Facts

Introduction

  • Speaker: Dr. Ekberg, holistic doctor and former Olympic decathlete.
  • Topic: Discrepancies and misinformation regarding cooking oils.
  • Objective: Understand basic principles about fats and oils to discern reliable information.

Common Misconceptions about Cooking Oils

  1. Polyunsaturated Fatty Acids are Healthy
    • Long-standing belief.
  2. Source Confusion
    • Healthy food source doesn't translate to healthy oil.
  3. Emphasis on Smoke Point
    • Misleading if underlying oil processing isn't considered.

Flaxseed Oil: A Case Study

  • High Omega-3 Content
    • Beneficial for cell membranes and anti-inflammatory pathways.
  • Not Suitable for Cooking
    • Low smoke point.
    • Polyunsaturated fatty acids are unstable and not meant for fuel.
  • Damage from Cooking
    • Becomes pro-inflammatory when damaged by heat.

Understanding Saturation in Molecules

  • Saturated Molecules
    • Fully occupied carbon bindings, stable, solid at room temperature.
  • Unsaturated Molecules
    • Double bonds create instability, lower melting points.
    • Monounsaturated vs. Polyunsaturated

Worst Cooking Oils

  • Flaxseed Oil: Very low smoke point, highly reactive.
  • Soybean, Canola, Safflower Oils: Similar issues.
  • Production Process
    • Solvent extraction, refining, bleaching - industrial processes damage oils.

Health Impacts of Processed Oils

  • High in Omega-6s
    • Leads to pro-inflammatory pathways.
  • Reactive Oxygen Species (ROS)
    • Damage tissues, promote insulin resistance, inflammation.
    • Associated with degenerative diseases.

Avocado Oil

  • Controversy
    • High smoke point but often refined and damaged.
  • Recommendation
    • Use unrefined, extra virgin for dressings, not for cooking.

Factors in Choosing Cooking Oils

  • Focus on How Food is Raised and Processed
  • Question Labels and Claims
  • Concern about Industrial Processing

Recommended Cooking Fats and Oils

  • Natural Meat Fats: Saturated, stable for moderate heat.
  • Olive Oil
    • Low saturation, suitable for low to medium heat.
    • Unprocessed, retains original flavor.
  • Coconut Oil
    • Highly saturated, mildly processed.
  • Butter and Ghee
    • Natural, flavorful, suitable for various cooking methods.
    • Ghee especially for high heat due to lack of protein residue.

Deep Frying and Cooking Practices

  • Deep Frying: Not recommended, compromises oils.
  • Repeated Heating: Leads to formation of harmful compounds.
  • Cooking Vessel Recommendations
    • Avoid Teflon, use stainless steel, cast iron, or ceramic.

Conclusion

  • Saturated Fats
    • Stable, healthy, satiating.
  • Essential Fatty Acids
    • Obtain from fresh food, not processed oils.
  • Key Takeaway
    • Focus on natural, minimally processed oils for health benefits.
