I've been tracking my meals with an app for three months now, and I'm struck by how much of my diet is ultra-processed food — about 60% of my calories come from things like flavored yogurt, protein bars, and frozen meals. We hear endlessly about cutting sugar or eating more greens, but what if the real problem is the level of processing itself, not just the nutrients? Does the degree of food processing matter more than the actual macro or calorie content for long-term health?
