Highly processed vegetable oils, derived from seeds and beans, have become a dominant part of modern diets despite significant health concerns. Historical biases in nutrition science, influenced by the vegetable oil industry, have promoted these oils despite evidence from controlled studies showing negative health outcomes. These oils are unstable, prone to oxidation, and can create toxic byproducts, particularly when exposed to heat, contributing to inflammation and chronic diseases. Although they can lower LDL cholesterol, studies have shown that this reduction does not necessarily improve heart health and may increase risks for other conditions like cancer. In contrast, traditional fats like extra virgin olive oil and omega-3-rich foods offer more stability and health benefits, emphasizing the need for a balanced, minimally processed approach to dietary fats.

In this episode, I talk with Nina Teicholz and Max Lugavere to explore the health impacts of different types of fats and oils, debunking misconceptions around cooking with extra virgin olive oil and emphasizing the dangers of industrial vegetable oils.
