Dr. Chris van Tulleken, a doctor and researcher, delves into the pervasive impact of ultra-processed foods on global health, revealing that these foods, engineered for overconsumption, now constitute 75% of global calorie intake. Driven by a 'food mafia' of powerful companies, these foods are linked to a pandemic of diet-related diseases, now surpassing tobacco as the leading cause of early death. Van Tulleken argues that addressing poverty could eliminate 60% of diet-related diseases, as financial constraints force many to consume harmful, ultra-processed foods. He disputes the simplistic 'calories in, calories out' approach, highlighting the complexities of human metabolism and the addictive nature of these foods. Van Tulleken's insights challenge the narrative of personal responsibility and call for systemic change to promote social justice and increase access to healthy, affordable food.
