Cancer survivors who consume more ultraprocessed foods may face a higher risk of death, according to new research published in Cancer Epidemiology, Biomarkers & Prevention. Lead author Marialaura Bonaccio found that higher intake of heavily processed foods was linked to increased mortality among survivors, even when adjusting for diet quality. Ultraprocessed foods, like packaged snacks, sugary drinks, and ready-made meals, may contribute to inflammation and other biological effects that increase mortality risk.
"The main takeaway is that higher consumption of ultraprocessed foods is associated with a significantly increased risk of both overall and cancer-specific mortality," Bonaccio said. The study followed over 800 cancer survivors over nearly 18 years and found those consuming the most ultraprocessed foods had a 48% higher risk of death from any cause and a 57% higher risk of death from cancer compared to those consuming the least.
Bonaccio recommends moving towards minimally processed foods and home-cooked meals to reduce reliance on ultraprocessed options.
