Florida Atlantic Study Links Ultra-Processed Foods to Increased Risk of Prostate Cancer

The study analyzed data from 17,024 men aged 18 and older who participated in the National Health and Nutrition Examination Survey from 2003 to 2023. Researchers utilized two 24-hour dietary recalls and the NOVA classification system to assess calorie intake from UPFs and correlated these levels with self-reported prostate cancer instances. Findings indicated that men consuming higher amounts of UPFs had a 24% to 34% greater risk of developing prostate cancer compared to those with lower intake levels, after adjusting for factors like age, race, and smoking status.

In the United States, ultra-processed foods account for approximately 60% of adults' and 70% of children's energy intake. These foods include items such as soft drinks, packaged cereals, snacks, and processed meats, which are made with refined ingredients and additives that enhance taste and shelf life at the expense of nutritional value.

Previous research has already identified various health issues linked to high UPF consumption, such as obesity and cardiovascular diseases. Notably, the mechanisms believed to underlie the cancer risk include metabolic disruption and inflammation, though specific data on prostate cancer risk related to UPF intake had been limited until now.

The results from this study underscore the pressing health concerns associated with UPF consumption in light of prostate cancer, which is the most frequently diagnosed cancer among men in the U.S. and the second leading cause of cancer deaths among them.

The researchers emphasized the necessity for more comprehensive observational studies and randomized trials to explore the effects of UPFs on health further. Charles H. Hennekens, M.D., the senior author, remarked on the importance of these findings, indicating that health professionals should guide patients towards healthier dietary choices and reduce UPF intake in their daily nutrition.

The American Cancer Society projects that over 333,000 men will be diagnosed with prostate cancer in the U.S. in 2026, and about 36,000 are anticipated to die from the disease. Globally, nearly 1.5 million men were diagnosed in 2022, with approximately 400,000 deaths from prostate cancer.

This research moves the dialogue on UPFs forward, highlighting public health challenges in reducing consumption of these widespread products. Co-author Timothy De Ver Dye, Ph.D., noted that overcoming barriers to healthy food access necessitates broad public health efforts beyond individual choices.

Study co-authors included FAU medical students Hunter Scott and John Dunn, along with Yanna Willett, a doctoral student at the University of Oxford.
