This podcast episode explores the flaws in the NOVA classification system, which categorizes foods based on their level of processing. The system often erroneously places nutritious foods in the same category as junk food, leading to biased research and a privileged perspective on nutrition. The episode emphasizes the need for a more nuanced approach to food processing that recognizes the nutritional value of some processed foods and considers various factors like health, accessibility, affordability, convenience, culture, heritage, and individual circumstances.
