Seed oils have become one of the most heated debates in food and nutrition. Are they toxic? Do they cause inflammation? And should we all be replacing them with olive oil or avocado oil?
In this episode of In Good Taste, I sit down with Dr Sarah Berry, Professor of Nutritional Sciences at King’s College London and Chief Scientist at ZOE, to unpack what the science actually says about cooking oils.
From sunflower and rapeseed oil to olive oil and ghee, we explore how fats work in the body, why misinformation spreads so easily online and what home cooks really need to know when choosing oils in their kitchens.
We also talk about affordability, flavour, cultural cooking traditions and whether expensive oils are always the healthiest choice.
If you are a food lover trying to make sense of conflicting advice about fats, this episode cuts through the noise.
