Consuming Ultra-Processed Foods Like Soda and White Bread Linked to Increased Risk of Early Death

New research highlights the alarming health risks associated with diets high in ultra-processed foods, which include items such as soda, white bread, and snacks laden with added sugars, salts, hydrogenated fats, artificial colors, preservatives, and starches. These foods constitute approximately 58% of the average American diet, marking the highest intake globally. The study found a direct association between increased consumption of ultra-processed foods (UPFs) and higher mortality rates.

According to lead researcher Eduardo Nilson, every 10% increase in the share of UPFs in a person's diet correlates with a 3% rise in the risk of death from all causes. The research, which pooled data from eight countries including the United States, revealed that the U.S. has the highest concentration of ultra-processed foods. Consequently, Americans face nearly a 14% increased risk of premature death, with an estimated 124,000 early deaths in 2018 attributable to UPF consumption.

Prior studies have linked UPFs to various health conditions such as cancers, obesity, and high blood pressure. However, this recent work provides a clearer understanding of how these foods, with their artificial ingredients and adverse nutritional profiles, contribute to overall mortality. Nilson explains that beyond the high sodium, trans fats, and sugar content, the extensive industrial processing and use of food additives further harm health.

The study also raises concerns about global consumption patterns. While high-income countries like the U.S. have relatively stable but high UPF intake, middle-income nations are experiencing a continuous increase. This trend suggests that the global burden of health issues related to UPFs will continue to grow, emphasizing the urgent need for policies to discourage their consumption and promote traditional dietary habits based on fresh, minimally processed foods.

Data for the study were collected from countries including Australia, Brazil, Canada, Chile, Colombia, Mexico, the UK, and the U.S. The findings underscore the importance of dietary reforms to reduce reliance on ultra-processed foods and mitigate their health impacts.
