High consumption of ultra-processed foods (defined as >4 servings daily) is independently associated with a 62% increased hazard of all-cause mortality compared to low consumption.

To lower your risk of early death, limit ultra-processed foods to less than 4 servings per day. Focus on reducing items like sugary drinks, processed meats, and packaged snacks, as these contribute most to the risk. Prioritize whole or minimally processed foods.
