Cardiologist José Abellán warned that these foods contribute to a global obesity crisis, noting that obesity cases have increased sevenfold over the last 40 years. He linked dietary patterns high in fats, sugars, and processed ingredients to cardiovascular disease, diabetes, and certain cancers. An extensive analysis published in Family Medicine and Community Health synthesized data from 51 studies involving approximately 8.8 million adults, identifying a proportional relationship between UPF intake and various health complications. Specifically, for every additional 100 grams of UPFs consumed daily, researchers found a 14% higher risk of cardiovascular problems, a 4% higher risk of cancer, a 31% rise in digestive diseases, a 27% increase in depression or anxiety, and a 23% increase in obesity. Recent data also links this intake to an 11% increase in high blood pressure. Research in JAMA Psychiatry and The Lancet has expanded these findings to mental and cognitive health. A pilot study led by Dr. Njaša Čagvedera from the University of California, San Francisco (UCSF) found that participants experienced a reduction in depression and anxiety symptoms after decreasing UPF intake by more than 85 percent. Dr. Čagvedera noted that these foods may damage the gut in ways that subsequently affect the brain, potentially through phenomena like “gut leakage.” New research from Virginia Tech and the Fralin Biomedical Research Institute, published in Nature Metabolism, further clarified the biological impact. A study of 57 healthy young adults found that ultra-processed meals trigger a more intense and prolonged insulin response and reduce the body’s ability to use carbohydrates as fuel compared to minimally processed meals, even when calories and macronutrients are identical. ## Timeline ### 2026-10-06: Virginia Tech study finds ultra-processed foods alter metabolism and brain activity A study published in Nature Metabolism reveals that ultra-processed foods trigger unique insulin responses and brain activity compared to minimally processed foods, even with identical calorie counts. 8 sources. https://clstr.news/cluster/metabolic-health-research-links-food-processing-and-lifestyle-to-diabetes-and-insulin-response ### 2026-10-04: UCSF study links reduced ultra-processed food intake to lower depression A UCSF study found that reducing ultra-processed food intake by over 85% can significantly lower symptoms of depression and anxiety in adults within four weeks. 2 sources. https://clstr.news/cluster/ucsf-study-links-reduced-ultra-processed-food-intake-to-lower-depression-1 ### 2026-10-02: Ultra-processed foods linked to chronic disease and mental health risks Research links ultra-processed food consumption to increased risks of chronic diseases, including cardiovascular issues, obesity, and diabetes, as well as significant impacts on mental health and cognition. 8 sources. https://clstr.news/cluster/ultra-processed-foods-linked-to-depression-and-cognitive-decline ### 2026-09-30: Ultra-processed foods linked to increased chronic disease risks A study of 8.8 million people links ultra-processed food consumption to increased risks of heart disease, cancer, obesity, and mental health issues like depression and anxiety. 4 sources. https://clstr.news/cluster/ultra-processed-foods-linked-to-serious-chronic-health-risks ### 2026-09-20: Cardiologist José Abellán warns of ultra-processed food risks Cardiologist José Abellán warns that ultra-processed foods and sugary drinks are major drivers of global obesity, cardiovascular disease, and cancer. 5 sources. https://clstr.news/cluster/cardiologist-jos-abelln-warns-of-ultra-processed-food-risks --- Cite as: Health risks of ultra-processed food consumption.
