Higher consumption of most ultra-processed foods is linked to a slightly higher risk of death, with ready-to-eat meat, poultry, and seafood based products, sugary drinks, dairy based desserts, and highly processed breakfast foods showing the strongest associations, finds a 30-year U.S. observational study. The results were published in the journal The BMJ.
The researchers say not all ultra-processed food products should be universally restricted, but that their findings “provide support for limiting consumption of certain types of ultra-processed food for long term health”. Mounting evidence links ultra-processed foods to higher risks of obesity, heart disease, diabetes and bowel cancer, but few long term studies have examined links to all causes and cause specific deaths, especially due to cancer.
To address this knowledge gap, researchers tracked the long-term health of 74,563 female registered nurses from 11 States in the Nurses’ Health Study (1984-2018) and 39,501 male health professionals from all 50 U.S. states in the Health Professionals Follow-up Study (1986-2018) with no history of cancer, cardiovascular diseases, or diabetes at study enrolment.
