World Nutrition Summit 2026: The New Conversation Around Food, Insulin Resistance and Metabolic HealthNutrition advice can feel more confusing than ever. Carbohydrates, fats, insulin resistance, metabolic health and disease prevention all generate fierce debate, but how do we separate strong scientific evidence from health hype? The World Nutrition Summit 2026, taking place at Hazendal Wine Estate from 14 to 16 October, brings together experts from South Africa and around the world to examine nutrition policy, metabolic disease, insulin resistance, preventative healthcare and the need for robust scientific debate. Liezel van der Westhuizen, fitness presenter, wellness correspondent, burnout and mental fitness coach, joins Africa Melane on CapeTalk and 702 to explore what metabolic health actually means, why nutrition science should never become a team sport, and the questions consumers should ask before accepting the latest diet claim as fact. Plus, discover the striking South African diabetes statistic that could change the way you think about preventative health.
