Ultra-Processed Foods and Prostate Cancer Risk: What Men Should Know
A new study is raising questions about the relationship between ultra-processed foods and prostate cancer risk—and the findings are worth paying attention to. Researchers found that men who consumed more ultra-processed foods had roughly a 24% to 31% higher reported risk of prostate cancer compared with men who consumed the least. I recently discussed the findings on FOX 2 Detroit and, with September marking Prostate Cancer Awareness Month, the study provides a useful reminder: prevention is not about one food or one test. It is about understanding your cumulative risk and acting on what you can control.
What Did the New Prostate Cancer Study Find?
The research, published in The American Journal of Medicine, analyzed data from 17,024 U.S. men whoparticipated in the National Health and Nutrition Examination Survey between 2003 and 2023.
Researchers estimated how much of each participant’s diet came from ultra-processed foods using two 24-hour dietary recalls. Men with higher consumption had approximately a 27% to 31% greater adjusted risk of prostate cancer in several of the study’s comparisons.
Those numbers deserve attention—but they also require context.
This was an observational analysis, not a randomized clinical trial. Prostate cancer diagnoses were self-reported, diet was estimated from only two days of food recall, and researchers could not establish that eating ultra-processed foods caused prostate cancer. Other factors—including family history, physical activity, body composition and differences in prostate cancer screening—could also influence the relationship.
The appropriate conclusion is not that a bag of chips causes prostate cancer. It is that higher long-term consumption of ultra-processed foods may be another meaningful marker of risk worth reducing.
What Actually Counts as an Ultra-Processed Food?
Not everything that comes in a package is unhealthy.
Frozen vegetables, canned beans, plain yogurt and other minimally processed foods can still be excellent choices. Ultra-processed foods are generally industrial formulations that contain refined ingredients, additives, flavorings, preservatives or other components rarely used in a home kitchen.
Common examples include:
- Sugary soft drinks
- Chips and packaged snack foods
- Cookies and packaged desserts
- Many sugary breakfast cereals
- Hot dogs and other processed meats
- Certain frozen pizzas and ready-to-eat meals
- Many fast-food products
The concern may extend beyond calories alone. Researchers have proposed several possible pathways connecting ultra-processed diets with poor health, including metabolic dysfunction, chronic inflammation, oxidative stress and changes in the gut microbiome. These mechanisms remain under investigation, particularly as they relate specifically to prostate cancer.
The practical goal is therefore not perfection. It is to shift the balance of your diet toward foods closer to their original form: vegetables, fruit, legumes, nuts, whole grains, fish and minimally processed sources of protein.
Prostate Cancer Risk Goes Beyond Your Diet
Diet is only one component of prostate cancer risk.
Age remains one of the strongest factors. Family history matters significantly: having a father or brother with prostate cancer more than doubles a man’s risk. Certain inherited mutations, particularly BRCA2, also increase risk. Black men in the United States face both a higher incidence of prostate cancer and a higher risk of dying from the disease.
That is why knowing your family history may be every bit as important as knowing what is on your dinner plate.
And because early prostate cancer frequently produces no symptoms, waiting until something feels wrong is not an effective screening strategy.
When Should You Start Prostate Cancer Screening?
Prostate screening should be individualized through a conversation with your physician.
The American Cancer Society recommends discussing screening beginning around:
- Age 50 for men at average risk
- Age 45 for men at higher risk, including Black men and those with a father or brother diagnosed before age 65
- Age 40 for men at particularly high risk, including those with multiple first-degree relatives diagnosed at an early age
The PSA blood test remains the foundation of prostate cancer screening, but a PSA should not always be viewed as a simple “normal versus abnormal” number. Trends over time can provide additional information. When PSA results or risk factors warrant further evaluation, tools such as prostate MRI, PSA density and targeted biopsy can help clinicians determine who truly needs additional testing. Modern prostate screening is increasingly about combining multiple pieces of information rather than reacting to a single laboratory value.
The Takeaway: Reduce Risk Where You Can—and Measure the Rest
You cannot change your age, genetics or family history. But you can influence your diet, metabolic health, exercise habits, body composition and whether you participate in appropriate screening.
Replacing some ultra-processed foods with minimally processed alternatives is a reasonable place to start. Swap soda for water or unsweetened beverages. Choose fruit or nuts instead of packaged snacks more often. Favor fresh proteins, vegetables and whole-food carbohydrates over meals built primarily around refined ingredients.
Then know your numbers.
At Synergy Longevity Centers, our approach is to evaluate health proactively—combining medical and family history with laboratory testing and advanced imaging when appropriate rather than waiting for symptoms to develop.

The goal is not to fear food. It is to understand risk—and make informed decisions while you still have the opportunity to influence it.
