Overview
- A cohort study of 802 cancer survivors found that those with the highest intake of ultra‑processed foods had a 48% higher all‑cause mortality and a 57% higher cancer mortality over a median 14.6 years of follow‑up.
- The mortality association persisted after adjusting for overall diet quality, and accounting for inflammatory markers and resting heart rate reduced the link by 37.3%.
- A Milbank Quarterly analysis by researchers from Harvard, Duke, and the University of Michigan argues many ultra‑processed foods are engineered for reinforcement using dose optimization and hedonic manipulation similar to tobacco strategies.
- The same analysis details that refined carbohydrates and fats activate separate gut–brain pathways and together can push mesolimbic dopamine responses up to 300% above baseline, supporting calls for tighter marketing and manufacturing controls.
- New U.S. research published in The American Journal of Medicine reports a 47% higher prevalence of cardiovascular disease among adults with the greatest ultra‑processed food consumption, based on nationally representative NHANES data.
