Angela welcomes Dr Sarah Berry to explore common misconceptions surrounding seed oils, including concerns about rancidity, oxidation, and their association with inflammation and cardiovascular disease.
Sarah presents evidence from her extensive research, arguing that seed oils, when consumed in moderation, do not pose significant health risks and may even offer benefits, such as lowering LDL cholesterol.
KEY TAKEAWAYS
Seed Oils Aren’t the Villains: Dr. Berry explains that seed oils have been misunderstood and demonised. They may lower LDL cholesterol and contain natural antioxidants like vitamin E, which protect against oxidation.
Processing Myths Debunked: Many fear the chemicals in seed oil production, but Dr. Berry notes that most are removed or present in trace amounts that pose no health risks.
Balance is Key: Olive oil remains the "king of oils," but a mix of oils, including rapeseed or sunflower, can provide various health benefits.
Omega-6 Concerns Are Overblown: High omega-6 intake is fine as long as there’s enough omega-3 in your diet to balance it out.
