Episode notes
Seed Oils Lack Human Evidence Of Harm
- Human outcome data do not support the claim that seed oils cause major health harms.
- Replacing saturated fat with polyunsaturated-rich seed oils lowers LDL and reduces cardiovascular risk.
Why Seed Oils Became A Cultural Target
- Seed oil criticism taps into broader narratives of industrialization and distrust of the food industry.
- Those narratives make the seed oil story compelling despite weak human outcome evidence.
Context Determines An Oil's Health Impact
- Olive oil sits outside the 'seed oil' critique and carries additional polyphenol and monounsaturated benefits.
- Food effects always depend on what they replace and the eater's baseline diet.
