Ultra-Processed Foods: A Health Concern for Americans

A growing concern in the United States is the high consumption of ultra-processed foods (UPFs), with a report from the Centers for Disease Control and Prevention revealing that more than 50% of total calories consumed by children and adults come from these foods.

The NOVA system, developed by researchers at the University of São Paolo in Brazil, is a widely used classification for defining UPFs. This system organizes foods into four groups based on their degree and purpose of processing.

1. Unprocessed or minimally processed foods: These include natural foods or those altered minimally, such as fruits, vegetables, beans, nuts, eggs, meat, plain yogurt, and coffee.
2. Processed culinary ingredients: Substances extracted or refined from Group 1 foods, used in cooking, such as sugar, honey, oils, butter, and vinegar.
3. Processed foods: Foods made by adding salt, sugar, or other substances to Group 1 foods, typically involving preservation or fermentation; examples are canned vegetables, salted nuts, cured meat, cheeses, and freshly made bread.
4. Ultra-processed foods: Industrial formulations mostly or entirely made from substances extracted from foods, derived from food constituents, or synthesized in labs. These products often contain additives like emulsifiers, bulking agents, thickeners, and undergo multiple industrial processes along with sophisticated packaging. Examples include soft drinks, commercially produced breads, flavored yogurts, breakfast cereals, frozen meals, potato chips, hot dogs, and candy bars.

Studies have shown a link between consumption of UPFs and weight gain, as well as a higher risk of deaths from cardiovascular disease and early death. A study led by researchers at Harvard T.H. Chan School of Public Health found that a high intake of UPFs may increase the risk of early death.

To identify UPFs, experts advise reading the ingredients list and nutritional facts panel. Dr. Brian Wojeck, an assistant professor of medicine at Yale School of Medicine, stated that UPFs typically contain little of the original foods. Jennifer Taylor, a registered dietitian nutritionist and Rutgers Family and Community Health sciences educator, suggests that a longer ingredients list and harder-to-understand ingredients may indicate an ultra-processed food.

Michele Polacsek, a professor of public health and director of the Center for Excellence in Public Health at the University of New England, notes that food labels do not list the industrial processes used in creating UPFs. Polacsek implies that a standard definition for UPFs could help promote healthier food choices and reduce the consumption of these foods.

To combat this issue, Polacsek suggests that policy makers create a standard definition for UPFs to help manufacturers, supermarkets, schools, and others make informed decisions about selling, buying, and consuming these foods. Taylor recommends making as many meals at home as possible and switching out one processed item for a less processed one on every grocery trip to limit UPF consumption.

Robert F. Kennedy Jr. has warned about the dangers of UPFs, linking them to the rise of chronic diseases in the U.S. Taylor emphasizes that every small step towards reducing UPF consumption can have a significant impact on one's health.

1. The high consumption of ultra-processed foods (UPFs) is a significant health concern, as studies indicate a link between UPF consumption and weight gain, cardiovascular disease, early death, and chronic diseases.
2. A report by the Centers for Disease Control and Prevention highlights that UPFs contribute to more than 50% of total calories consumed by Americans, both children and adults.
3. Due to the refined and industrial nature of UPFs, they often contain additives and undergo multiple processes, making them distinct from unprocessed or minimally processed foods.
4. To identify UPFs, experts suggest reading the ingredients list and nutritional facts panel, noting that a longer ingredients list and hard-to-understand ingredients may indicate an ultra-processed food.
5. Health professionals advocate for a standard definition for UPFs to help promote healthier food choices, reduce UPF consumption, and combat the rise of chronic diseases linked to UPFs.
6. Policy makers are encouraged to create a standard definition for UPFs, promoting informed decision-making regarding their sale, purchase, and consumption across various sectors like manufacturers, supermarkets, schools, and households.
7. Every effort to reduce UPF consumption and prioritize healthier food choices contributes toward personal growth, health-and-wellness, fitness-and-exercise, nutrition, cardiovascular-health, education-and-self-development, and overall wellbeing.
