Certain type of food linked to premature deaths in 8 countries, study finds

The U.S. government’s plans to phase out artificial food dyes have brought the spotlight on the dangers of consuming ultraprocessed foods. A recent study published in the American Journal of Preventive Medicine has revealed that these foods are linked to premature deaths in eight countries.

The meta-analysis of observational cohort studies conducted from November 2023 to July 2024 focused on the risk of all-cause mortality and the “epidemiologic burden” from ultraprocessed food consumption. The study looked at people with low, intermediate, and high consumption of ultraprocessed foods in various countries.

The researchers found an association between ultraprocessed foods and all-cause mortality in all eight countries, with risks varying from 4% in Colombia to 14% in the U.K. and U.S. The study concluded that reducing ultraprocessed food intake should be included in national dietary guidelines and addressed in public policies.

In a statement, study co-author Eduardo A.F. Nilson emphasized the increasing evidence of health risks associated with ultraprocessed foods. He noted that these foods have been linked to 32 adverse health outcomes, including obesity, cardiovascular disease, diabetes, and mental health issues. The impact of ultraprocessed foods on all-cause mortality was found to be significant in countries where they are predominant in diets, such as the U.S. and the U.K.

Dr. John Whyte, Chief Medical Officer of WebMD, expressed concerns about the prevalence of ultraprocessed foods in the American diet. He highlighted the importance of consuming whole foods and plant-based diets, as seen in “blue zones” where people live longer and healthier lives.

In response to these findings, the U.S. government has announced plans to phase out synthetic dyes from the food supply. Health and Human Services Secretary Robert F. Kennedy Jr. and FDA Commissioner Dr. Mary Makary cited studies linking petroleum-based synthetic dyes to health conditions like ADHD, obesity, diabetes, cancer, and GI issues.

As the nation re-evaluates its food consumption habits, the focus is shifting towards promoting healthier, whole foods and reducing the consumption of ultraprocessed foods. By addressing the risks associated with these foods and implementing policies to phase out harmful additives, the government aims to improve public health and reduce the burden of preventable diseases.
