Study Reportedly Links Ultra-Processed Foods to Increased Cancer Risk

Researchers in France and Brazil have concluded that a 10 percent increase in the consumption of ultra-processed foods is associated with a “significant increase of greater than 10% in risks of overall and breast cancer.” Thibault Fiolet, et al., “Consumption of ultra-processed food and cancer risks: results from NutriNet-Santé prospective cohort,” BMJ, February 14, 2018. The study, which involved surveying records of more than 100,000 participants, asserts that ultra-processed fats and sauces along with sugary products and drinks were associated with an increased risk of overall cancer, while ultra-processed sugary products were also associated with a higher risk of breast cancer.

The researchers hypothesized that the findings were caused by the “generally poorer nutritional quality of diets rich in ultra-processed foods,” the wide range of additives used, and heat-related processing and preparation that produce neoformed contaminants such as acrylamide.
