A new study<\/a> in the Journal of the Academy of Nutrition and Dietetics<\/em> has found that 60% of foods purchased by Americans contain technical food additives such as coloring or flavoring agents, preservatives, or sweeteners. This represents a 10% increase since 2001. Manufacturers have also increased the average number of additives in purchased food and beverage products from 3.7 in 2001 to 4.5 in 2019. These findings indicate that prevalence of food additives is on the rise.<\/p>\n\n\n\n

While food additives can extend shelf life and improve palatability, their health consequences are not fully understood, though mounting evidence points to high intake of ultra-processed foods \u2014 which often contain multiple additives \u2014 is connected to a multitude of health risks<\/a>. Assessing food-additive exposure over time is a vital step in understanding its role in nutrition-related diseases, negative changes to the gut microbiome, and other adverse health outcomes associated with ultra-processed foods.<\/p>\n\n\n

\u201cOur research clearly shows that the proportion of ultra-processed foods with additives in Americans\u2019 shopping carts increased significantly between 2001 and 2019. We observed this trend across all food and additive categories,\u201d noted lead investigator Elizabeth K. Dunford, PhD<\/a>, Food Policy Division, The George Institute for Global Health, University of New South Wales, Sydney, Australia, and Department of Nutrition, Gillings Global School of Public Health, The University of North Carolina at Chapel Hill, USA.<\/p>\n\n\n\n

By 2019, more than half of the overall packaged food and beverage products bought by U.S. households contained three or more additives. Furthermore, and perhaps most concerning, a 22% higher percentage of baby food purchases were ultra-processed and contained additives. \u201cThese findings give us reason for concern, given the growing evidence linking high consumption of processed foods with adverse health outcomes,\u201d noted Dr. Dunford, adding that the investigators observed one positive trend, a decrease in the use of added flavors in carbonated soft drinks.<\/p>\n\n\n\n

By 2019, more than half of the overall packaged food and beverage products bought by US households contained three or more additives.<\/em><\/strong><\/p>\n<\/div>\n<\/div>\n\n\n\n

U.S. consumers purchase more than 400,000 different packaged food and beverage products each year at grocery stores, with new products constantly being added to shelves. Increased ultra-processed foods means that Americans are consuming more sugar, sodium, and saturated fats.<\/p>\n\n\n

Barry M. Popkin, PhD<\/figcaption><\/figure><\/div>\n\n\n

\u201cWith manufacturers producing foods and beverages with an increasingly higher number of additives, it is more important than ever to understand what is in the foods that Americans are buying and eating,\u201d commented the study\u2019s senior investigator, Barry Popkin, PhD<\/a>, W.R. Kenan, Jr. Distinguished Professor, Department of Nutrition, Gillings Global School of Public Health, and the Carolina Population Center, The University of North Carolina at Chapel Hill, USA.<\/p>\n\n\n\n

\u201cU.S. consumers are demanding a much higher level of transparency from brands and retailers than in previous years. We hope the findings from this study will be used to inform policymakers on where Americans \u2013 especially babies \u2013 are being exposed to additives, and how the packaged food supply is changing,\u201d Dr. Popkin said.<\/p>\n\n\n\n

This is the first study to examine what U.S. consumers are purchasing \u2013 rather than relying on reported food and beverage intake \u2013 to evaluate exposure to food additives in ultra-processed foods, which is essential for assessing their role in the associated adverse health risks. The investigators used Nielsen Homescan Consumer Panel data from 2001 and 2019 to examine the proportion of products purchased by U.S. households containing four common technical food additives (colors, flavors, preservatives, and nonnutritive sweeteners) and to ascertain whether purchases have changed over time through the products\u2019 scanned Nutrition Facts Panels. Previous research had been hampered by the lack of publicly available ingredient databases identifying and quantifying top additives in U.S. foods.<\/p>\n\n\n\n

\u201cThe findings from this study could be used to inform policymakers on where American consumers are getting an increasing number of additives and how the packaged food supply is changing. The results can also set the foundation for future work in this area and provide direction for future researchers,\u201d added Dr. Dunford. \u201cAt a minimum, I hope this work leads to further investigation into the types and amounts of ingredients being used in the manufacturing of baby food products.\u201d<\/p>\n\n\n\n

An accompanying editorial<\/a> by Mona S. Calvo, PhD, and Jaime Uribarri, MD, of The Icahn School of Medicine at Mount Sinai, NY, New York, USA, cites the study\u2019s contributions, \u201cBy providing data on exposure to food additives in ultra-processed foods found in grocery-purchased foods over time, Dr. Dunford\u2019s team is leading the way with much-needed research. Their novel method enabled them to document food additive-exposure changes over time and by food and additive category,\u201d said Dr. Calvo. <\/p>\n\n\n\n

Dr. Uribarri added, \u201cMost importantly, the authors\u2019 unique approach enabled exposure estimates in the understudied, vulnerable populations of infants and children.\u201d<\/p>\n\n\n\n
