A study recently published in the European Journal of Nutrition found that consuming ultraprocessed foods may be linked to an increased risk of developing certain types of cancer, as well as other health issues. The study, which analyzed the dietary habits of over 450,000 adults participating in the European Prospective Investigation into Cancer and Nutrition, found that people who consumed a greater amount of ultraprocessed foods had a higher risk of developing cancers of the upper digestive tract, such as mouth, throat, and esophageal cancer. Specifically, researchers found that individuals who consumed 10% more ultraprocessed foods had a 23% higher risk of head and neck cancer and a 24% higher risk of esophageal adenocarcinoma.
In addition to cancer, the study also found a link between ultraprocessed foods and other health issues, such as obesity, heart disease, and depression. The study indicated that ultraprocessed foods are often calorie-dense and are considered to be a driver of excess weight. However, statistical analysis found that increases in body fat accounted for only some of the statistical association between ultraprocessed food and cancers of the upper digestive tract, implying that other factors may be at play. The study suggested that ingredients such as emulsifiers, preservatives, artificial sweeteners, and toxins found in food packaging might also play a role in the link between ultraprocessed food and cancer or other diseases.
While the new study adds to a growing body of evidence suggesting a link between ultraprocessed foods and various health issues, including cancer, researchers noted that much more research and data collection are needed to fully understand the link. Previous studies have also found a connection between ultraprocessed foods and cancer, as well as other health issues. Despite these findings, it is still unclear whether ultraprocessed foods directly cause health issues or if other underlying factors, such as general health-related behaviors and socioeconomic position, are responsible for the association.
As more research is conducted in this area, it’s becoming increasingly clear that reducing the consumption of ultraprocessed foods and focusing on a diet rich in whole, unprocessed foods may have significant health benefits. Although further research is needed, the study underscores the importance of considering the impact of diet on overall health and well-being.
