Ultra-processed food consumption, cancer risk, and cancer mortality: a large-scale prospective analysis within the UK
The increasing prevalence of ultra-processed foods in people’s diets is concerning, especially in regards to potential health implications. A recent study conducted within the United Kingdom sought to examine the association between ultra-processed food consumption and cancer risk and mortality. The study utilized a large sample size and a prospective design in order to find evidence-based information on this relationship.
The study was conducted over a seven-year period and included over 450,000 people—primarily women—with no prior history of cancer. Participants were asked to complete a dietary questionnaire that assessed their usual consumption of ultra-processed food products. These products included ready-to-eat snacks, packaged breads and cakes, sodas and sweetened beverages, and processed meats.
The study results showed a positive and statistically significant association between ultra-processed food consumption and an increased risk of cancer. Specifically, individuals who had higher intakes of ultra-processed foods were 24% more likely to develop cancer than those who had lower intakes. This association was found to be strongest for breast cancer and colorectal cancer.
Moreover, the study also found that cancer mortality was significantly higher in individuals with higher intakes of ultra-processed foods. This association was especially strong for those with colorectal cancer, with a 64% higher risk of death among those with higher intakes of ultra-processed foods.
Overall, this large-scale prospective study provides evidence of an association between ultra-processed food consumption and an increased risk of cancer and cancer mortality. This information can help to inform public health initiatives aimed at reducing cancer risk and improving overall health.
