Episode notes
Seed Oils and Linoleic Acid
- Seed oils contain significant amounts of omega-6 polyunsaturated fats, especially linoleic acid, which is often the focus of health concerns.
- Intake of linoleic acid has increased in recent decades due to changes in food supply and processing advances.
Oxidation Prone Polyunsaturated Fats
- Polyunsaturated fats in seed oils are chemically more prone to oxidation due to their multiple double bonds.
- This characteristic contributes to concerns about their stability and potential health effects during cooking.
Seed Oil Composition Changes
- Common seed oils like soybean, canola, and corn oil contain significant linoleic acid, while sunflower and safflower oils now often have higher oleic acid.
- These changes improve oil stability and shelf life, impacting their biochemical profile in the food supply.
