Corporate lobbying, food deserts, and cultural habits drive unhealthy diets for children and adults worldwide
Original framing: “Worry about what your children eat, but don’t forget your own diet” — New Scientist
Meta‑analyses link ultra‑processed food consumption to increased risk of obesity, type 2 diabetes, and cardiovascular disease, independent of caloric intake. Nutritional epidemiology also demonstrates that food environment variables—price, availability, and marketing exposure—are stronger predictors of diet quality than individual knowledge alone.
The obesity epidemic is rooted in a confluence of corporate power, policy choices, and cultural shifts that together constrain dietary agency across generations.
Historical subsidies and colonial land‑use policies have entrenched reliance on ultra‑processed foods, while contemporary marketing exploits both children and adults, perpetuating inequitable health outcomes. Indigenous food sovereignty, scientific evidence, and cross‑cultural practices demonstrate viable alternatives that can be scaled through comprehensive regulation, agroecological investment, and inclusive education. By foregrounding marginalised voices and exposing the trickster logic of blame‑shifting, policymakers can redesign the food system to be resilient, equitable, and health‑promoting for all.
