Ultra-Processed Foods Linked to Higher Cancer Mortality Risk – Study

Ultra-Processed Foods Linked to Higher Cancer Mortality Risk – Study

February 17, 2026 discoverhiddenusacom Health

A high consumption of ultra-processed foods is linked to a significantly increased risk of mortality among individuals already diagnosed with cancer. This finding stems from a study conducted by the Epidemiology and Prevention Unit at the Irccs Neuromed of Pozzilli, supported by the Fondazione Airc per la Ricerca sul cancro, and published in the journal Cancer Epidemiology, Biomarkers & Prevention of the American Association for Cancer Research.

The Study and Its Findings

The data indicates that cancer patients who consume large amounts of ultra-processed foods face a 48% higher risk of death from all causes, and a 59% higher risk of cancer-related mortality, compared to those who limit their intake.

The analysis is part of the Moli-sani project, initiated in 2005 and based at Irccs Neuromed. This project has involved over 24,000 adults residing in the Molise region of Italy. Researchers identified 802 participants – 476 women and 326 men – who had already received a cancer diagnosis at the time of enrollment.

Participants’ dietary habits were assessed using the food frequency questionnaire from the Epic (European prospective investigation into cancer and nutrition) study. Foods were categorized according to the Nova system, which classifies foods into four groups based on the level and purpose of industrial transformation.

Did You Know? The Moli-sani project began in 2005 and has followed over 24,000 adults in the Molise region of Italy.

Participants were divided into three categories based on their daily consumption of ultra-processed foods and followed for nearly 15 years. Statistical analyses were adjusted for numerous confounding factors, including age, sex, smoking status, body mass index, physical activity, medical history, cancer type, and overall diet quality, as measured by adherence to the Mediterranean diet.

Expert Insight: The meticulous adjustment for confounding factors in this study – including pre-existing health conditions and dietary patterns – strengthens the potential link observed between ultra-processed food consumption and mortality rates in cancer patients. This highlights the complexity of nutritional research and the importance of controlling for variables that could influence outcomes.

What Might Happen Next

Further research could explore the specific components of ultra-processed foods that contribute to these increased risks. It is also possible that future studies will investigate whether interventions aimed at reducing ultra-processed food consumption could improve outcomes for cancer patients. Analysts expect that these findings may lead to more detailed dietary recommendations for individuals undergoing cancer treatment and recovery.

Frequently Asked Questions

How were foods classified in the study?

Foods were classified according to the Nova system, which categorizes them based on the level and purpose of industrial transformation.

How many participants were included in the study who had a cancer diagnosis?

The study included 802 participants (476 women and 326 men) who had already received a cancer diagnosis at the time of enrollment.

What factors were considered when analysing the data?

The statistical analyses were adjusted for factors such as age, sex, smoking, body mass index, physical activity, medical history, cancer type, and adherence to the Mediterranean diet.

Considering these findings, how might individuals diagnosed with cancer approach dietary choices to potentially support their health and well-being?
